STP45N40DM2AG from STMicroelectronics, in a TO-220. 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; Zener-protected with V(BR)GSO of ±30 V min and an absolute maximum VGS of ±25 V, with a gate threshold of 3 V min, 4 V typ and 5 V max at ID = 250 µA. |
| 2 | D | passive | Drain, connected internally to the TAB; V(BR)DSS is 400 V min, continuous ID is 38 A at Tcase = 25 °C, and pulsed IDM is 152 A. |
| 3 | S | passive | Source; continuous body-diode current ISD is 38 A and pulsed ISDM is 152 A. |
