IRF531-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; controls the channel with VGS(th) of 1.0 to 3.0 V and an absolute maximum of ±20 V. |
| 2 | D | passive | Drain, connected to the tab; VDS max 60 V and continuous ID of 20 A at TC = 25 °C. |
| 3 | S | passive | Source; body diode continuous current is limited by the 68 A pulsed rating (ISM) and VSD max is 1.5 V at IS = 17 A. |
