FQA28N50 from onsemi, in a TO-3P-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-source voltage limited to ±30 V absolute maximum, with VGS(th) of 3.0 to 5.0 V at ID = 250 µA. |
| 2 | D | passive | Drain; drain-source voltage 500 V maximum and continuous drain current 28.4 A at TC = 25°C (113.6 A pulsed). |
| 3 | S | passive | Source; the body diode carries a continuous forward current of up to 28.4 A. |
