**VBsemi Elec** · MOSFETs · TO-252

TK20P04M1-VB from VBsemi Elec, in a TO-252. 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; gate-source voltage limit is ±20 V and the gate threshold voltage is 1.5 V min to 2.5 V max at VDS = VGS, ID = 250 µA. |
| 2 | D | passive | Drain, also connected to the tab; drain-source voltage is rated at 40 V with continuous drain current of 55 A at TC = 25 °C and pulsed drain current of 200 A. |
| 3 | S | passive | Source; continuous source-drain diode current is 90 A at TC = 25 °C with body diode forward voltage of 0.8 V typ and 1.2 V max at IS = 22 A. |
