MSD40P45 from Bruckewell, in a TO-252. 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 ±20 V, with threshold of -1.0 to -2.5 V and suited to -4.5 V gate drive. |
| 2 | D | passive | Drain (also the exposed tab); drain-source voltage -40 V and continuous drain current -45 A at TC=25°C. |
| 3 | S | passive | Source; continuous source current -45 A and pulsed source current -90 A through the body diode. |
