1200 V TrenchStop® IGBT — what it is and where it fits
The Infineon IGW40N120H3FKSA1 is a 1200 V, 80 A TrenchStop® IGBT in a TO-247-3 through-hole package. It uses a Trench Field Stop structure with standard gate drive thresholds, rated for 483 W maximum power dissipation. The 2.4 V typical saturation voltage at 15 V gate and 40 A collector keeps conduction losses manageable in hard-switching inverter stages. With a 175°C maximum junction temperature, this part is suited for industrial motor drives, uninterruptible power supplies, welding machines, and solar inverters where high-voltage switching and thermal cycling are routine.
Package and assembly considerations
The PG-TO247-3-1 package is a standard through-hole footprint with a large tab for heatsink mounting. MSL is not stated in the listing, but TO-247 devices typically handle reflow or wave solder without moisture sensitivity issues — still, check the MSL on the reel label before the oven. The through-hole format means manual insertion or wave solder; no tombstoning risk, but plan for adequate clearance around the tab for a heatsink clip or screw.
