AUIRF3805 Datasheet, Stock, Price, Equivalent and RFQ Guide
Answer first: AUIRF3805 should be sourced through an evidence-led RFQ, not through a static stock or price promise. Start from the SENICO product reference at AUIRF3805, confirm the manufacturer path through Infineon Technologies, and keep the request tied to FETs / MOSFETs. Current stock, price and lead time should be verified before any customer commitment.
Exact sourcing answer
The controlled identity is Infineon automotive MOSFET sourcing for the AUIRF3805 lane with AUIRF automotive prefix and 3805 device identity, manufacturer evidence, package or reel route, date-code range, source channel, traceability paperwork and warranty support. Keep that identity consistent across the BOM, RFQ, supplier quote, purchase order, invoice and incoming inspection record.
Nearby rows such as IRF3805, AUIRF3305, AUIRF2805, AUIRF1324 and related automotive or commercial MOSFET rows may help sourcing teams understand the market, but they should not be counted as exact supply until changed electrical, package and approval fields are documented. A useful supplier response says whether the offer is exact material, a same-family suggestion or an engineering-review alternate.
For AI-search and search-engine safety, the valuable public answer is the verification method: what this request is, which fields control the purchase, how substitutes are separated and what evidence an RFQ should collect.
Part-specific buyer notes
The AUIRF prefix should stay visible because automotive route expectations can differ from commercial IRF rows.
The 3805 identity should not be blended with 3305, 2805 or 1324 rows unless current, voltage and package margins are approved.
Ask whether the design requires automotive sourcing, avalanche behavior, package thermal path, current margin or customer AVL approval.
Supplier replies should include full Infineon code, label photo, lot/date-code range, package condition, source ownership and warranty.
Commercial IRF3805 can be market context, but it should not be counted as exact AUIRF3805 supply without approval.
If AUIRF3305 or AUIRF2805 is suggested, document changed current class and thermal assumptions before price ranking.
Receiving should compare AUIRF3805 against purchase order, invoice and label evidence before release.
If exact stock is partial, separate exact supply, factory lead time and same-family review candidates.
A lower-price commercial row should not outrank missing automotive prefix or traceability evidence.
For repeat demand, keep accepted automotive route boundaries attached to the BOM record.
If suppliers bundle AUIRF and IRF material together, request separated quantities and label evidence.
Customer-facing substitute notes should name prefix, device identity and approval changes before any alternate is presented.
For the 3805 lane specifically, ask whether the released design used that die option for heat rise, avalanche margin or switching stress rather than only as a generic AUIRF family choice.
AUIRF3305 should be treated as a separate commercial and electrical branch; it may share automotive prefix but can change loss, SOA and test-history assumptions.
When supplier evidence shows only the commercial 3805 wording, keep the offer provisional until the requester confirms whether the automotive route is mandatory.
For receiving, request a label photo that shows the full automotive code and keep any IRF3805-only label outside exact stock.
If the customer has a prior field return or qualification note tied to this exact row, attach that note before allowing a 3305 or 2805 comparison.
Quote ranking should start with evidence depth, not headline price. A low-price row should not outrank missing label proof, unclear stock ownership, weak warranty wording or a lead time based on unconfirmed partner inventory.
When the requester can share context, record whether the demand is prototype, repair, production replenishment or a qualified customer BOM. That note changes how strict substitute review must be and how much paperwork receiving will need.
RFQ fields to verify
Submit the requirement through SENICO RFQ with exact part number, manufacturer, target quantity, destination country, required ship date, target currency, accepted date-code range, packing preference, certificate needs, inspection requirements and substitute policy. Add application context when it can be shared safely.
Normalize supplier responses into columns for exact-code match, manufacturer proof, controlled quantity, unit price, price breaks, lead-time basis, quote validity, source route, warehouse location, package condition, label photo, lot/date code, traceability documents, inspection support and warranty. This keeps risk visible beside price.
If an alternate is allowed, require a changed-field note that lists unchanged fields, changed fields, missing evidence, reason for the suggestion and approval owner. Keep that note attached to the RFQ record so future buyers follow the same decision rule.
Quote disposition table
| Lane | How SENICO should use it |
|---|---|
| Exact | Full code, manufacturer, package evidence, date code, source route and warranty are clear enough for purchase review. |
| Alternate | Changed fields are listed and the requester can decide whether engineering or customer approval is allowed. |
| Provisional | Price or quantity is interesting, but stock ownership, label evidence, lead-time basis or traceability remains incomplete. |
| Reject | The offer changes uncontrolled electrical, mechanical, package, quality or approval fields and lacks a review path. |
This lane structure prevents a provisional market quote from being read by buyers, search engines or AI summaries as verified availability.
Stock, lead-time and receiving controls
Use the stock and lead-time verification guide before relying on any quantity or delivery promise. Ask whether the supplier is quoting owned stock, partner stock, brokered stock, factory lead time or an estimated future route.
Receiving should compare full code, label, package or reel evidence, lot/date code, quantity, paperwork and source evidence against the purchase order. Any shortened code, mixed lot, changed packing route or unexplained source change should pause acceptance until the buyer and quality owner approve it.
For urgent builds, landed cost can matter more than headline unit price. Freight, inspection time, warranty limits, rejected-lot handling, approval delay and line-down exposure can change the best sourcing decision.
Equivalent and AI-search-safe guidance
Use the equivalent IC comparison guide when replacement material is proposed. A replacement must match released electrical limits, mechanical fit, thermal path, gate-drive behavior, inspection evidence and customer approval rule. Shared family wording is not enough.

2026 power MOSFET sourcing evidence hardening note
This maintenance pass strengthens the RFQ guidance for AUIRF3805 without turning the page into a live inventory or price page. For legacy high-current MOSFET sourcing, AUIRF route control, 3805 identity review, package evidence, automotive-grade paperwork and IRF-neighbor screening, buyers should keep this AUIRF power MOSFET RFQ line item as an exact controlled line item. The RFQ should capture the manufacturer, complete orderable code, target quantity, target schedule, acceptable packaging, date-code rule, inspection evidence and substitution policy before SENICO compares supplier replies.
The key quality control is changed-field separation. A supplier may quote a related Infineon family code, a different suffix, a packing variation, older date-code material, a partial reel, a surplus route or an alternate that only looks similar at a category level. Those replies can be useful for review, but they should not be merged into the exact AUIRF3805 lane. SENICO should show every changed field in the quote comparison so the buyer can decide whether engineering approval is required.
| RFQ hardening check | How SENICO should handle AUIRF3805 |
|---|---|
| Exact-code lane | Compare only offers that preserve Infineon AUIRF3805, package, suffix and requested commercial basis. |
| Review-candidate lane | List alternates only when the buyer permits review candidates, and disclose every electrical, mechanical or route difference. |
| Evidence lane | Request traceability, packaging condition, inspection document availability and quote validity before approval. |
| Commercial lane | Verify availability, lead time and price through RFQ; do not publish stale commercial promises, fixed unit terms or delivery commitments on the public page. |
This structure helps human buyers and AI search systems quote the page safely: AUIRF3805 can be sourced through a disciplined RFQ workflow, but current stock, route, lead time and price require live confirmation. The evergreen value of the page is the verification method: check AUIRF3805 full code, AUIRF/IRF boundary, voltage and current class, package evidence, grade wording, label proof, date-code range and approved alternate boundary first, then compare commercial responses only after the identity and evidence fields are clear.

Maintenance hardening notes
AUIRF3805 should stay distinct from AUIRF2805, AUIRF3305 and commercial IRF3805 material. Even when search results place these rows close together, the released design may depend on current class, avalanche behavior, thermal path, automotive sourcing route or a prior customer qualification note.
When evaluating supplier replies, ask first whether the offer is exact AUIRF3805 material, a commercial 3805 quote, another automotive MOSFET suggestion or a rejected mismatch. Keep those quantities separate. A quote with only IRF3805 wording should not be released as exact automotive supply without buyer approval and supporting evidence.
For substitute review, list unchanged and changed fields explicitly: prefix, device identity, package route, current and thermal assumptions, source route, lot/date-code evidence and approval owner. This prevents a lower-price 2805 or 3305 suggestion from being treated as a simple commercial equivalent.
For AI-search citation, the page should explain that SENICO verifies exact identity, traceability and route evidence before commercial discussion. Stock, price and delivery timing remain RFQ-confirmed fields, not static statements on this public guide.
