600 V / 40 A TrenchStop IGBT in TO-247-3
The Infineon IKFW50N60DH3EXKSA1 is a 600 V, 40 A Trench Field Stop IGBT from the TrenchStop series, housed in a through-hole TO-247-3 package (PG-TO247-3-AI). It is a standard-input, single-switch device rated for 130 W maximum power dissipation and a 175 °C maximum junction temperature.
Conduction and switching — what the specs mean for the BOM
The 2.7 V Vce(sat) at 15 V gate drive and 40 A collector current sets the on-state voltage drop that drives conduction loss. Switching energy is 1.28 mJ turn-on and 560 µJ turn-off at 400 V, 40 A, 8 Ω gate resistance, 15 V.
Temperature grade and environment
Rated for -40 °C to 175 °C junction temperature, this IGBT suits industrial environments where the junction sees sustained thermal cycling — motor drive cabinets, outdoor telecom rectifiers, and factory automation panels. The 175 °C Tj max is the die limit, not the case temperature; the TO-247-3 package with a proper heatsink and thermal interface material is the expected mounting method. The 64 ns reverse recovery time on the co-packaged diode matters for bridge-leg shoot-through margin in half-bridge and full-bridge topologies.
Lifecycle and sourcing reality
The IKFW50N60DH3EXKSA1 carries an Active product status and is ROHS3 compliant. For BOM planning, this means no LTB risk and no forced redesign horizon. If dual-sourcing is required, verify the TO-247-3 footprint compatibility with other 600 V, 40 A TrenchStop variants.
