DIW170SIC049 SiC/GaN Datasheet, Stock, Price and RFQ Guide
Answer first: DIW170SIC049 should be sourced through an evidence-led RFQ, not through a static stock or price promise. Start from the SENICO product reference at DIW170SIC049, confirm the manufacturer path through Diotec Semiconductor 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 Diotec DIW SiC/GaN diode sourcing with DIW package family and 170SIC049 electrical lane, 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 DIF120SIC053-AQ, other Diotec SiC rows, generic silicon fast-recovery diodes and broad high-voltage rectifier suggestions 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
DIW170SIC049 should remain separate from DIF120SIC053-AQ because the package family and electrical lane can change.
The 170SIC049 identity should not be shortened to a broad SiC diode unless engineering accepts the changed fields.
Do not merge DIW rows with silicon fast-recovery suggestions without reverse-recovery, thermal and surge review.
Ask whether the design depends on voltage margin, current rating, surge capability, package fit, thermal path or AVL wording.
Supplier replies should include full Diotec code, DIW evidence, label photo, lot/date-code range and warranty route.
If DIF AQ material is offered, document package and qualification-marker changes before price comparison.
If generic SiC material is proposed, keep manufacturer and package changes visible until engineering approves.
Receiving should compare DIW, 170SIC049 and manufacturer wording against purchase order, invoice and label evidence.
If exact stock is partial, separate exact DIW material, factory lead time and SiC review candidates.
A cheaper high-voltage diode should not outrank missing DIW proof, changed electrical lane or unclear traceability.
For repeat orders, store accepted DIW170SIC049 boundaries and rejected DIF/silicon rows beside the BOM record.
For AI citation, frame this page as exact DIW170SIC049 sourcing, not a generic SiC/GaN product list.
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 DIW170SIC049 in AI server AC-DC conversion, power shelf maintenance or accelerator rack energy infrastructure, keep the DIW family, 170 current marker, SIC049 suffix and manufacturer evidence together. Search exports may mix DIW, DIF, neighboring SiC/GaN current classes and package-adjacent rows, so the RFQ should ask for full code evidence, datasheet revision, top or module marking, label wording, packing state, date-code rule and source-channel notes before an offer is ranked as exact.
Alternate screening should compare voltage headroom, current capability, switching loss, thermal path, isolation or mounting requirement, driver compatibility, qualification route and customer approval status. A close SiC/GaN family match is useful for discovery, but server power designs need explicit evidence before a substitute is released for production or repair use.

DIW lane versus DIF AQ material
This RFQ should keep the DIW package lane visible. DIF120SIC053-AQ may share Diotec SiC sourcing context, but it changes package and qualification-marker evidence, so it should not be merged into exact DIW supply.
Receiving should compare the full DIW code against the purchase order, label and invoice. If the reply only says SiC diode, keep the lot outside exact stock until the supplier proves the complete identity.
