**VBsemi Elec** · MOSFETs · TO-252

MDD3754RH-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 limited to ±20 V, with threshold VGS(th) of -1.0 V to -3.5 V at ID = -250 μA. |
| 2 | D | passive | Drain, the center lead and the mounting tab; VDS rated -40 V with continuous drain current of -50 A at TC = 25 °C. |
| 3 | S | passive | Source; continuous source (body diode) current is -50 A, with a forward diode voltage of -1 V typical at IF = -50 A. |
