FQA40N25 from onsemi, in a TO-3P. 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; controls the channel, with VGS rated ±30 V max and threshold of 3.0 V to 5.0 V. |
| 2 | D | passive | Drain; 250 V max drain-source voltage and 40 A continuous drain current at TC = 25°C. |
| 3 | S | passive | Source; connected to the body diode anode, with 40 A max continuous diode forward current. |
