The fourth pin is a Kelvin-emitter connection that separates the gate-drive return from the main power current path, which reduces the effective gate-loop inductance and lets the device switch cleaner at higher di/dt. Maximum junction temperature is 175 °C. ## Switching loss and gate drive budget At 600 V, 40 A, 12 Ω, 15 V, turn-on energy is 2.18 mJ and turn-off energy is 1.3 mJ. Gate charge is 190 nC. Turn-on delay is 30 ns and turn-off delay is 280 ns at 25 °C, giving a usable dead-time window for the complementary switch in a half-bridge leg. ## Package and mounting — the Kelvin-emitter advantage The PG-TO247-4 package is a through-hole device with a separate emitter sense pin. In a standard 3-pin TO-247 the gate-drive loop includes the power emitter inductance; here the drive loop is isolated from the main current commutation, which reduces the voltage spike seen at the gate during switching transients. Pulsed collector current capability is 160 A, useful for short-circuit withstand and inrush events. ROHS3 compliance is listed.","metaTitle":"Infineon IKY40N120CH3XKSA1 IGBT, 1200 V, 80 A, TO-247-4","metaDescription":"Infineon IKY40N120CH3XKSA1 TrenchStop IGBT, 1200 V, 80 A, 500 W, TO-247-4.
