Product details

The Infineon IPA90R340C3XKSA1 is a 900 V N-channel CoolMOS power MOSFET in a TO-220 Full Pack through-hole package.

For prototype or pre-production designs, evaluate a current-production 900 V CoolMOS; the pin-compatible footprint and similar gate-drive requirements make the transition manageable with a layout review.

Package and thermal handling

The TO-220 Full Pack (PG-TO220-FP) isolates the drain tab electrically, so you can bolt it directly to a grounded heatsink without a thermal pad or mica washer. For continuous operation near 15 A, a forced-air heatsink or a larger clip-on extruded profile is necessary to keep the junction below 150°C.

Frequently asked questions

What is the replacement for IPA90R340C3XKSA1?

No official replacement order code is listed for the IPA90R340C3XKSA1. For new designs, evaluate a current-production 900 V CoolMOS MOSFET from Infineon's active portfolio. The TO-220 Full Pack footprint and 10 V gate-drive voltage are common across the family, but verify the pinout and thermal performance against your specific load conditions.

Is IPA90R340C3XKSA1 obsolete?

Yes, the IPA90R340C3XKSA1 is listed as Obsolete. Infineon no longer manufactures it, and the supply path is through surplus and independent distribution.
