Frequently Asked Questions

Which designs are a good fit for FS400R12A2T4 when 400 A is required?

FS400R12A2T4 is a practical integrated circuit choice when the design requirements match 400 A. Engineers should compare the manufacturer data, Other package, and operating conditions against the schematic before approving it for a production BOM.

How should procurement teams qualify FS400R12A2T4 before placing an RFQ?

Procurement should verify the Infineon ordering code, lifecycle status, RoHS or lead-free evidence, and traceable date-code availability. The known 400 A requirement helps screen alternates before requesting pricing for production quantities.

What footprint details matter most when replacing FS400R12A2T4 on an existing board?

Check the Other package, land pattern, height constraints, and 51 pins against the original PCB files. Even when electrical ratings match, a mismatch in pins or package style can block assembly release.
