650 V, 74 A TrenchStop® IGBT in TO-220-3
The Infineon IKP40N65F5XKSA1 is a 650 V, 74 A TrenchStop® IGBT in a through-hole PG-TO220-3 package. It is designed for hard-switching applications such as motor drives, uninterruptible power supplies, and industrial inverters where low conduction and switching losses are needed. The 95 nC gate charge keeps the gate-drive power budget modest, and the 175 °C maximum junction temperature allows operation in high-ambient enclosures or engine compartments.
Switching performance and thermal headroom
Rated at 74 A continuous collector current with a 120 A pulsed capability, this IGBT handles the inrush and overload events common in motor-start and capacitor-charging circuits. The switching energy of 360 µJ (on) and 100 µJ (off), measured at 400 V, 20 A, and 15 Ω gate resistance, gives a realistic loss figure for hard-switching topologies. The 60 ns reverse recovery time of the co-packaged diode reduces turn-on losses in the complementary switch. The 2.1 V saturation voltage at 15 V gate drive and 40 A collector current defines the on-state loss at typical operating points. With a 255 W power dissipation limit and 175 °C junction rating, the designer has headroom to push switching frequency or ambient temperature as long as the thermal path to the heatsink is adequate.
Lifecycle and BOM fit
Listed as Active with ROHS3 compliance, the IKP40N65F5XKSA1 carries no last-time-buy risk for current production. The standard TO-220-3 footprint and through-hole mounting simplify assembly and field replacement.
