# IKZA75N65EH7XKSA1

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

IKZA75N65EH7XKSA1 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 for VCE = 650 V and 80 A DC collector current (limited by bondwire). |
| 2 | E | passive | Power emitter of the IGBT and anode of the antiparallel diode, carrying the main load current of up to 80 A DC and 300 A pulsed. |
| 3 | K | passive | Kelvin emitter sense connection used as the gate-drive return, separate from the power emitter; internal emitter inductance is 13 nH typ. measured 5 mm from case. |
| 4 | G | input | Gate input of the IGBT with a maximum gate-emitter voltage of ±20 V (±30 V transient for tp ≤ 10 µs, D < 0.01) and a threshold of 2.9 V min to 4.8 V max. |
