900 V CoolMOS™ N-channel — high-voltage primary switch
The Infineon IPI90R500C3XKSA2 is a 900 V, 11 A N-channel CoolMOS™ MOSFET in a TO-262-3 through-hole package. The 500 mOhm Rds(on) at 10 V gate drive and 68 nC gate charge at 10 V suit medium-frequency switching.
Package and mounting — TO-262-3 through-hole
The TO-262-3 (PG-TO262-3-1) is a through-hole package with long leads, intended for heatsink mounting. The tab is the drain; the two short pins are gate and source. The 156 W power dissipation at case temperature requires a thermal interface — plan for a TO-220-style clip or screw mount with thermal compound. The through-hole form factor suits point-to-point wiring or prototype boards where surface-mount reflow is not available.
