KGF25N120KDA from KEC Semicon, in a TO-247-3. 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 | G | input | Gate; gate-emitter voltage limited to ±20 V (VGES), threshold VGE(th) 4.5 V min to 7.0 V max at IC=25 mA. |
| 2 | C | passive | Collector (also connected to the mounting tab in the package drawing); VCES 1200 V, IC 50 A at Tc=25 °C and 25 A at Tc=100 °C, ICM 75 A. |
| 3 | E | passive | Emitter; IGBT emitter and anti-parallel diode anode, with diode continuous forward current IF 25 A at Tc=100 °C. |
