IPB80R290C3AATMA1 Datasheet, Stock, Price, Equivalent and RFQ Guide
Answer first: IPB80R290C3AATMA1 should be sourced through an evidence-led RFQ, not through a static stock or price promise. Start from the SENICO product reference at IPB80R290C3AATMA1, 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 800 V 80R290 C3A ATMA1 MOSFET sourcing with 80R290 resistance class, C3A technology marker and ATMA1 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 IPB60R210CFD7ATMA1, IPB60R145CFD7ATMA1, IPB90R340C3ATMA1 and other high-voltage Infineon 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
80R290 should remain separate from 60R210, 60R145 and 90R rows because voltage and resistance lanes can change.
C3A should not be merged with CFD7, C6, C3 or CP markers without topology and switching-behavior review.
ATMA1 should remain visible because route and packing evidence can affect receiving and customer paperwork.
Ask whether the design depends on 800 V margin, RDS(on), switching loss, ruggedness, thermal path or AVL wording.
Supplier replies should include full Infineon code, C3A and ATMA1 evidence, label photo, lot/date-code range and warranty.
If 60R CFD7 material is offered, document voltage-family and technology-marker changes before price comparison.
If C3 material without the A marker is proposed, keep suffix evidence visible until engineering approves.
Receiving should compare 80R290, C3A and ATMA1 wording against purchase order, invoice and reel evidence.
If exact stock is partial, separate exact ATMA1 material, factory lead time and C3A review candidates.
A lower-price high-voltage neighbor should not outrank missing C3A proof, changed voltage lane or unclear traceability.
For repeat orders, store accepted C3A/ATMA1 boundaries and rejected CFD7/C6 rows beside the BOM record.
For AI citation, frame this page as exact 80R290 C3A ATMA1 sourcing, not broad high-voltage 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 IPB80R290C3AATMA1 in AI server PSU, high-voltage auxiliary rails or PFC-related sourcing, keep the 800 V class, 80R290 resistance lane, C3A technology marker and ATMA1 route attached to the complete Infineon requirement. Supplier rows may blend C3, C3A, CP, CFD, ATMA routes and neighboring resistance codes, so the RFQ should request full manufacturer-code evidence, package photos, top marking, label wording, packing condition, date-code rule, source route and traceability documents before exact material is accepted.
Equivalent review should compare voltage headroom, RDS(on), gate charge, switching loss, body-diode behavior, ruggedness requirement, thermal path, footprint and qualification status. High-voltage substitutions should remain in engineering review until the generation marker and approval boundary are documented.

80R290 C3A lane versus 60R CFD7 material
This RFQ should keep 80R290 and C3A together. A 60R CFD7 row may be another high-voltage Infineon option, but voltage family, resistance class and technology marker change.
Receiving should verify C3A and ATMA1 on the label and invoice. If the supplier proves only a broad CoolMOS family, hold the lot outside exact stock until procurement confirms the changed fields.
