Reported by Aetrix Electronics on 2026-10-10. Summarized and analyzed by XAIPART Editorial.
What happened
According to a September 16, 2026 customer notice, onsemi will implement price adjustments on a "broad range of products" effective October 10, 2026.S1 The company attributes the move to continuing increases in raw-material, manufacturing, energy and infrastructure costs that it says can no longer be fully absorbed through internal efficiency measures.S1
The notice also cites stronger demand in power, industrial and data-center applications, the same demand drivers named in an earlier March 16 letter that led to a limited-range adjustment effective April 1, 2026.S1 Unlike the March letter, the September notice reviewed by Aetrix does not explicitly state how existing backlog will be repriced.S1 No portfolio-wide percentage and no affected-MPN list were disclosed; affected part numbers will be communicated through authorized distributor representatives.S1
The demand context has measurably strengthened since April. onsemi's Q2 2026 revenue reached $1.604 billion, up 9% year over year, with the Power Solutions Group at $829 million, up 19% year over year; the company said AI data centers were its fastest-growing business and expected revenue from that market to more than double in 2026.S1 Separately, onsemi disclosed AI data-center platform wins with Great Wall, launched the GaNEXUS portfolio from 40 V to 650 V, and announced a Fab Right reset in July including agreements to divest two manufacturing facilities.S1 At its September 16 Investor Day, onsemi framed a $213 billion market opportunity and introduced an Embedded Power Platform it says can deliver three to five times higher power density.S1

Background timeline
- - onsemi issues its first 2026 customer notice citing a "limited range of products," effective April 1, and explicitly covering backlog scheduled to ship on or after April 1.S1
- - onsemi announces agreements to divest two manufacturing facilities under its Fab Right strategy to improve cost structure.S1
- - onsemi issues the new pricing notice for a broad range of products, effective October 10, and holds its 2026 Investor Day the same day.S1
- - the broad price adjustment takes effect.S1
XAIPART take
Technical impact
Design exposure concentrates in power conversion: power MOSFETs, EliteSiC, GaNEXUS, gate drivers, controllers, rectifiers and bipolar discretes all share wafer, assembly and test economics tied to onsemi's expanding data-center and industrial content. Because no MPN-level price file is public, alternate-source qualification on paired devices such as a MOSFET plus its controller should be checked before redesigns. High total inventory of roughly 192 days does not guarantee availability of a specific package, qualification grade or quantity for a given MPN.
Market impact
Sourcing conditions favor the supplier: portfolio lead times lengthened from about 27 weeks to roughly 32 weeks in Q2 while distribution inventory fell to about 10.1 weeks, giving onsemi more leverage to enforce product-level pricing. Buyers with open orders face a specific commercial gap, since the September notice contains no backlog clause equivalent to the March letter's treatment of POs scheduled to ship on or after April 1. Contract terms, debit arrangements and scheduled ship dates may therefore determine whether an existing order is repriced.
Action
Before October 10, confirm for each production-critical MPN whether it appears in the distributor price file, what the post-increase unit price is, and whether pricing follows PO date, ship date or contract terms. Compare current stock, confirmed incoming material, new-production lead time and NCNR or reschedule restrictions before switching to a substitute. Qualification path should be weighed alongside price, because a cheaper alternate that misses the production window has limited value.
XAIPART Forecast
XAIPART expects the actual price movement to be uneven by product family rather than uniform: by 2026-12-31, published distributor price files for onsemi power MOSFET, EliteSiC and GaNEXUS lines should reveal MPN-level changes that vary across families, and if the disclosed changes do not exceed the single-digit range on at least some AI data-center power SKUs while lead times remain above 30 weeks, this forecast is wrong. XAIPART analysis.
Facts are as reported by the cited source. The design-in, sourcing and forward-looking statements above are XAIPART's analysis, not the source's claims. The backlog-repricing clause in the September notice is based on the single copy reviewed by Aetrix; the portfolio-wide percentage, affected-MPN list and per-category price changes were not disclosed by onsemi at publication.
Corrections: none at publication. This brief will be updated with a timestamp if the source corrects its report.
