STMicroelectronics · MOSFETs · D2PAK
STB28NM50N from STMicroelectronics, in a D2PAK. 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 terminal of the N-channel MOSFET; the datasheet gives a maximum gate-source voltage of ±25 V (VGS). |
| 2 | D | passive | Drain terminal of the N-channel MOSFET, rated 500 V drain-source voltage (VDS) and 21 A continuous drain current at TC = 25 °C. |
| 3 | S | passive | Source terminal of the N-channel MOSFET, rated for a 21 A continuous source-drain current and 84 A pulsed source-drain current. |
