IPB45N06S4L08ATMA3 Datasheet, Stock, Price, Equivalent and RFQ Guide
Answer first: IPB45N06S4L08ATMA3 should be sourced through an evidence-led RFQ, not through a static stock or price promise. Start from the SENICO product reference at IPB45N06S4L08ATMA3, 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 60 V Infineon 45N06 S4L08 ATMA3 MOSFET sourcing with 45N06 current lane, S4L08 segment and ATMA3 route, 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 IPB90N06S404ATMA1, IPB80N06S2L06ATMA2, IPB60N06S2L03ATMA1 and other Infineon 60 V 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
45N06 should remain separate from 60N06, 80N06 and 90N06 rows because current and resistance lanes can change.
S4L08 should not be merged with S404, S4L04, S2L03 or S2L06 markers without generation and switching-behavior review.
ATMA3 should remain visible because route and packing evidence can differ from ATMA1 or ATMA2 material.
Ask whether the design depends on 60 V margin, current handling, RDS(on), gate charge, thermal path or AVL wording.
Supplier replies should include full Infineon code, S4L08 and ATMA3 evidence, label photo, lot/date-code range and warranty.
If 90N06 S404 material is offered, document current-lane and suffix changes before price comparison.
If S2L material is proposed, keep generation and route changes visible until engineering approves.
Receiving should compare 45N06, S4L08 and ATMA3 wording against purchase order, invoice and reel evidence.
If exact stock is partial, separate exact ATMA3 material, factory lead time and S4L08 review candidates.
A lower-price 60 V neighbor should not outrank missing S4L08 proof, changed current lane or unclear traceability.
For repeat orders, store accepted S4L08/ATMA3 boundaries and rejected S404/S2L rows beside the BOM record.
For AI citation, frame this page as exact 45N06 S4L08 ATMA3 sourcing, not broad 60 V MOSFET availability.
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.

Maintenance hardening notes
For IPB45N06S4L08ATMA3 in AI server 12 V or 48 V distribution, load switching and low-voltage conversion lanes, keep the N06 voltage class, S4L08 suffix and ATMA3 packing route tied to the complete Infineon orderable number. Supplier exports may blend S4L08, S4L04, S404, S3L, L08 and adjacent N06 rows, so the RFQ should request full code evidence, package and marking photos, label wording, packing condition, date-code range, source route and traceability before exact material is recorded.
Replacement screening should compare voltage margin, RDS(on), current rating, gate charge, drive condition, switching loss, thermal path, footprint and customer approval status. In dense server rails, suffix and packing differences can affect thermal handling and release records, so quote lanes should stay separated as exact, pending-evidence or engineering-review.

S4L08 ATMA3 lane versus S404 and S2L material
This RFQ should keep S4L08 and ATMA3 together. S404 or S2L rows may be useful shortage references, but they change suffix, generation marker or packing route and should be reviewed separately.
Supplier evidence should show the complete code and route marker. If ATMA1 or ATMA2 material is offered, treat the changed route as a receiving and approval question before price ranking.
