The 5.7 A continuous current at 25°C is derated to about 3.6 A at 100°C case temperature; the 32 W dissipation limit at Tc=25°C sets the practical thermal ceiling. Gate charge of 34 nC at 10 V is moderate, so the gate driver doesn't need to be oversized. Infineon lists the IPA90R1K0C3XKSA1 as Obsolete. The date-code and lot traceability on any offered stock should be verified, as gray-market material for an obsolete CoolMOS part is a common counterfeit risk. ## Package and temperature grade — installation context The PG-TO220-FP (Full Pack) is a through-hole package with a fully molded back — no exposed metal tab. This simplifies assembly: you bolt it directly to the heatsink without a sil-pad or mica washer, though thermal compound is still recommended. The input capacitance of 850 pF at 100 V Vds is modest, so switching losses at frequencies up to 100 kHz are reasonable for a 900 V device.","metaTitle":"Infineon IPA90R1K0C3XKSA1 CoolMOS N-Ch 900V 5.7A MOSFET","metaDescription":"Infineon IPA90R1K0C3XKSA1 CoolMOS N-channel MOSFET, 900V Vdss, 5.7A Id, 1 Ohm Rds(on).
