STP40NF20-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 of the N-channel MOSFET, with gate-source voltage rated at ±25 V (absolute maximum), and VGS of 10 V used for the stated RDS(on) of 0.048 Ω at 3 A. |
| 2 | D | passive | Drain of the N-channel MOSFET, rated for 200 V drain-source voltage and 50 A continuous drain current at TC = 25 °C, with junction and storage temperature range of -55 to 175 °C. |
| 3 | S | passive | Source of the N-channel MOSFET, serving as the reference for gate-source voltage and the source-drain diode, with a pulsed source current (ISM) of 36 A. |
