Laid off from Infineon Technologies.

What Infineon Technologies layoffs have meant for employees

Four places carry most of Infineon's US notices since 2022, and all four have a history under other names. Champion Court in San Jose is the headquarters address in Cypress's 10-K, El Segundo is the home address in International Rectifier's 10-K, and that same filing lists Temecula and Mesa among its fabrication plants. Those places account for 741 jobs out of 853 in our WARN tracker since 2022, and Infineon's 2025 annual report lists International Rectifier HiRel Products and Spansion LLC as wholly owned units. Cypress filed notices in San Jose in 2015 and 2016, and Champion Court has turned up in all three California rounds since 2024, 183 jobs in all. If a package reaches you and it's tied to years of service, the start date it uses is worth checking against your original hire date, which may be older than your time under the Infineon name.

Three of Infineon's US plants show how much the form of an exit matters to the people inside. Temecula drew a closure notice. Austin's Fab 25 went to SkyWater, and Evertiq's report said its employees joined the buyer, so those jobs changed hands instead of ending. At Mesa, a spokesperson's August statement in KTAR's report had the plant closing and its production going mainly to foundry partners, and Infineon's notice covered the layoffs. The annual report filed the Austin sale under shedding smaller sites for economies of scale, with long-term supply agreements keeping the capacity available, and it called the sale of the former Cypress site in Bangkok pending. If you worked in Austin, the date your employer changed is the line between Infineon's record and SkyWater's.

Germany and the US look different in these numbers. Chief executive Jochen Hanebeck, in dpa's report, ruled out forced layoffs in Germany when he gave the August 2024 job figures, and said the relocations covered high-wage countries, North America included. In fiscal 2025 Infineon's average headcount fell 1% in Germany and 19% in the US. That US drop includes the Austin staff who left with the sale, so it isn't a layoff count. The annual report dates its Step Up cost program to May 7, 2024, and reports €232 million in restructuring and closure costs in fiscal 2024 and €139 million in fiscal 2025, most of it tied to the program. California's reports name no program, so neither they nor the annual report tie a given notice to Step Up.

Notice timing has differed by the kind of cut. Each of the three California layoff rounds shows an effective date 14 days after its notice date in the state's 2024-25 report and 2025-26 report, while the Temecula closure showed 62 in its 2022-23 report. Those are the dates on past rounds, and they don't set a pattern for any later notice. The reports list dates and counts, so they can't say whether the two weeks marked the end of a paycheck or just the last day on site. If your letter lists more than one date, it's worth getting clear on what each one refers to, whether that's the last day of work, of pay or of benefits.

Our California, Arizona and Washington unemployment pages cover the three states with Infineon notices since 2025. If a letter reached you and it lists dates, it's the document worth keeping, since a state list gives only a count for a site.

What to do if you're laid off from Infineon Technologies

• File for unemployment in the state where you worked. Benefits run from your filing date, and severance usually doesn't block you. Infineon Technologies's biggest hubs: California, Arizona, Washington. Somewhere else? Every state is here.
• Apply for financial and hardship assistance. Unemployment supplements income, but food benefits, health coverage and utility help are often available as well. Here's some of what Infineon Technologies's hub states run: California, Arizona, Washington, and every other state is here.
• Mind the health insurance window. Losing coverage opens a 60-day special enrollment period, and an ACA plan usually beats unsubsidized COBRA. Compare your options before the employer coverage lapses, and read how the COBRA clocks run if you are weighing it seriously.
• Get your real runway number. Severance plus savings divided by reality. The calculator takes five minutes.
• Know which clocks are already running. Severance review windows, COBRA election, visa grace periods, and 401(k) rollovers all run on federal deadlines that started at termination. All five deadlines are here.
