IKY40N120CS6

Infineon Technologies · IGBT Transistors / Modules · TO-247-4

IKY40N120CS6 from Infineon Technologies, in a TO-247-4. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 C passive Collector of the IGBT (cathode of the anti-parallel diode), rated 1200V collector-emitter voltage and 40A DC at Tc=100°C.
2 E passive Power emitter connection carrying the main collector current (up to 40A DC at Tc=100°C), with 13nH internal emitter inductance.
3 K passive Kelvin emitter (driver return) pin for the gate drive reference, separate from the power emitter.
4 G input Gate input of the IGBT, with gate-emitter voltage of ±20V (25V transient for tp ≤0.5µs) and threshold of 5.1V to 6.3V.
