Infineon told customers on February 5 that it will raise prices on selected power switches and related ICs from April 1, 2026, and the new pricing also applies to backlog scheduled to ship on or after that date. OEM buyers and turnkey PCBA teams should act before month-end because this is a quote and backlog problem first. If a customer approval, PO release, or shipment date crosses April 1, the cost file can change even when the build plan does not.
Infineon tied the move to tight supply in parts of its power portfolio, higher raw-material and infrastructure costs, and added fab investment. One day earlier, the company raised its 2026 investment plan to about EUR2.7 billion and said a large share would go to AI-related power capacity, including a faster ramp at its new Dresden Smart Power Fab.
Weak demand in parts of the auto and industrial market does not cancel this risk. It makes the exposure narrower. Buyers should look at the exact Infineon lines in the BOM, not the headline for the whole semiconductor market.
📊 Industry-Wide Repricing Cycle
Infineon's move follows a broader trend among top-tier semiconductor suppliers as they adjust to new manufacturing costs. For a complete view of the 2026 pricing landscape, also refer to:

The pressure is not spread evenly
Infineon’s own February 4 analyst statement showed two different conditions at the same time. Automotive revenue was down sequentially as customers kept managing inventory. But the company also said design wins were building in non-drivetrain automotive power and analog, including 48V power-steering, steer-by-wire, automotive-grade MOSFETs, analog power-management ICs, and gate drivers. That is the part of the automotive BOM where buyers should expect more pricing pressure.
The industrial picture is also split. Infineon said core industrial demand was still shallow and the inverter market was roughly flat, but grid infrastructure was one of the few areas that rose substantially. The same statement pointed to projects tied to energy storage, UPS, solid-state circuit breakers, and solid-state transformers. Power-sector OEMs using Infineon in conversion, switching, and protection stages should read the price notice against that backdrop, not against weaker demand in unrelated industrial categories.
Lead-time risk is not gone because the market is uneven. Infineon said its AI-related growth is limited by how fast it and its manufacturing partners can add capacity. That matters in late March. A buyer rush to lock pricing before April 1 can tighten available stock and push more business into backlog or split shipments.
What changes in the quote file and build plan
Quotation validity needs immediate review. Any quote still open on March 31 with Infineon power switches, gate drivers, power ICs, or automotive power semiconductors should be repriced against the April file and checked against shipment terms on backlog. A sales quote can stay unchanged on paper while the component cost has already moved underneath it.
BOM cost needs a line-by-line review, not a blanket surcharge. The affected categories sit in places that move board cost quickly: EV auxiliary power, onboard charging support circuits, DC-DC conversion stages, industrial drives, UPS boards, energy storage controls, and high-current automotive body and chassis electronics. If Infineon content sits in more than one stage of power conversion or protection, the increase can stack inside the same assembly.
Approved alternatives need more discipline than usual. In automotive builds, a substitute may trigger fresh checks on AEC qualification status, EMC behavior, thermal margins, firmware interaction, safety documentation, or customer approval. In power products, a substitute can change switching behavior, efficiency, heat, or magnetics stress even when the pinout looks close enough at first pass.
ACE Electronics can review the BOM, reprice the affected Infineon lines, screen approved alternates, and tie that work to component sourcing and the PCBA build schedule.
Production scheduling also needs a hard split before April 1. Parts that must stay with Infineon should be locked now for April and May builds. Parts that already have approved alternates should be separated and moved into an engineering-confirmed second path. Do not leave both groups mixed in one release. That is how one repriced part delays a full assembly lot.
What OEM buyers should do before April 1
Start with open quotes, backlog, and released-but-unbought build plans. Pull every program that uses Infineon power switches, power ICs, gate drivers, automotive MOSFETs, or related analog control parts. Then confirm three things with the channel: the new effective price, the shipment date tied to that price, and whether existing backlog keeps old pricing or rolls to the April file.
Next, sort the BOM into two lists. The first list is parts that stay with Infineon because the design, qualification file, or customer approval does not leave room to move. The second list is parts that already have alternates, or can be changed without reopening too much validation work. Buyers who do this after April 1 are negotiating from the wrong side of the date.
