# STP140NF75-VB

**VBsemi Elec** · MOSFETs · TO-220AB

STP140NF75-VB from VBsemi Elec, in a TO-220AB. 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; absolute maximum gate-source voltage is ±20 V, with a gate threshold voltage of 2 V min to 4 V max at ID = 250 µA. |
| 2 | D | passive | Drain; withstands 80 V drain-source voltage and carries up to 160 A continuous at TC = 25 °C (500 A pulsed, t = 100 µs). |
| 3 | S | passive | Source; carries the 160 A continuous drain current at TC = 25 °C, and the body diode is rated 250 A pulsed. |
