**Wolfspeed** · MOSFETs · TO-247-4

E3M0075120K from Wolfspeed, 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 | Drain | passive | Drain terminal (also connected to the tab), rated for VDSmax of 1200 V and continuous drain current of 32 A at TC = 25 °C. |
| 2 | Power Source | passive | Power source terminal carrying the main drain-source current path (32 A continuous at TC = 25 °C, 80 A pulsed). |
| 3 | Driver Source | passive | Separate driver source (Kelvin source) pin used as the gate-drive return to reduce switching losses and gate ringing. |
| 4 | Gate | input | Gate terminal with absolute maximum -8/+19 V and recommended turn-off/turn-on gate voltage of -4 V...0 V / +15 V. |
