KGF75N65KDF N-channel IGBT — 650V, 100A, 484W, TO-247, with anti-parallel diode

The KGF75N65KDF is a high-voltage, high-current N-channel IGBT (Insulated Gate Bipolar Transistor) with an integrated anti-parallel freewheeling diode, housed in the robust TO-247 through-hole package. Rated at 650V collector-emitter voltage and 100A continuous collector current at 25°C, it is designed for demanding power switching applications including solar inverters, UPS systems, industrial motor drives, and induction heating equipment.

With a low saturation voltage of V_CE(sat) = 1.77V (typ.) at 25°C and a maximum junction temperature of 175°C, the KGF75N65KDF delivers efficient, thermally robust power conversion. The integrated anti-parallel diode eliminates the need for an external freewheeling diode in bridge and half-bridge topologies.
