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

IKY120N65EH7XKSA1 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 and cathode of the antiparallel diode, rated VCE = 650 V, with DC collector current up to 160 A at Tc = 25 °C (limited by bondwire) and pulsed collector current up to 480 A. |
| 2 | E | passive | Power emitter of the IGBT and anode of the antiparallel diode, carrying the main load current (IC = 120 A rated, diode IF up to 160 A at Tc = 25 °C). |
| 3 | K | passive | Kelvin (auxiliary) emitter connection for the gate drive return, used for the gate-emitter voltage VGE of ±20 V maximum (±30 V transient for tp ≤ 10 µs). |
| 4 | G | input | Gate of the IGBT, with VGE limited to ±20 V (±30 V transient, tp ≤ 10 µs) and a threshold voltage VGEth of 2.9 V min to 4.8 V max at IC = 1.05 mA. |
