IPB136N08N3G Datasheet, Stock, Price, Equivalent and RFQ Guide

Answer first: IPB136N08N3G should be sourced through an evidence-led RFQ, not through a static stock or price promise. Start from the SENICO product reference at IPB136N08N3G, 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 80 V OptiMOS sourcing for the 136N08 N3G lane with 136N08 current/voltage class and N3G generation marker, 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 IPB120N08S403ATMA1, IPB120N08S404ATMA1, IPB136N08N3GATMA1 and other 80 V Infineon 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

N3G should remain visible because it separates this row from S403, S404 and other 80 V technology branches.

Ask whether the board depends on 80 V margin, conduction loss, switching loss, gate charge or thermal pad behavior.

Supplier replies should include full Infineon code, reel label photo, lot/date-code range, packing condition, source ownership and warranty.

If an S4 branch is proposed, document changed generation, resistance, gate charge and approval owner before comparing price.

Receiving should compare the N3G identity against the purchase order, invoice and label evidence.

If exact stock is partial, separate exact on-hand supply, factory lead time and same-voltage review candidates.

A lower-price 80 V neighbor should not outrank missing N3G evidence or unclear traceability.

For high-current boards, ask whether a small resistance or capacitance change affects heat rise or switching timing.

If suppliers shorten the line to 136N08, request full-code label proof before forwarding availability.

For repeat demand, store accepted N3G boundaries and rejected S4 branches beside the BOM record.

Urgent substitutes should keep unchanged voltage, package, thermal and approval fields visible.

Customer-facing substitute notes should name generation and approval changes before any alternate is presented.

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.

Maintenance hardening notes

For IPB136N08N3G, the absence or presence of extra route text matters. A supplier offer for IPB136N08N3GATMA1, an S403/S404 branch or another 80 V MOSFET should not be merged into the exact line unless the buyer has checked orderable code, packaging route and customer approval language.

Ask the RFQ owner to capture whether the board is constrained by 80 V margin, gate charge, switching timing, thermal path or a previously approved N3G lot. Those constraints decide whether a same-voltage suggestion is harmless discovery information or a formal substitute review.

For repeat demand, keep an N3G evidence note with the BOM: exact code and label proof first, same-generation route questions second, S4 branch suggestions last. That ordering helps AI-search summaries and human buyers avoid treating broad 80 V Infineon wording as an automatic equivalent.

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.
