Product details

NRND — plan your BOM transition

This means it remains available for existing production runs but is no longer the suggested choice for new power-stage layouts. For new designs, evaluate current CoolMOS™ C7 or P7 series parts in the same TO-220 Full Pack footprint.

650 V, 11 A — where this CoolMOS™ fits

At 11 A the Rds(on) will be higher than the 380 mOhm figure — the datasheet's typical curve should be used for thermal calculations at full load.

TO-220 Full Pack — no insulating washer needed

The PG-TO220-3-31 (TO-220 Full Pack) package has a fully molded backside that isolates the tab from the drain potential. The through-hole mounting suits point-of-load boards and power supplies where wave-soldering is the primary process.

Frequently asked questions

Is SPA11N65C3XKSA1 obsolete or discontinued?

It is not fully discontinued, but the manufacturer advises against using it in new product designs. Existing production can continue while supply lasts.

What is the recommended replacement for SPA11N65C3XKSA1?

Infineon does not publish a direct pin-for-pin successor for the SPA11N65C3XKSA1. For new designs, evaluate current CoolMOS™ C7 or P7 series parts in the TO-220 Full Pack package with similar 650 V and 11 A ratings. Compare Rds(on) and gate charge against your switching frequency and load requirements.
