Vishay Intertech · MOSFETs · TO-252

SQD40P10-40L_GE3 from Vishay Intertech, 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 of the P-channel MOSFET; gate-source voltage is rated at ±20 V (VGS limit on page 1).
2 D passive Drain of the P-channel MOSFET, electrically connected to the tab; drain-source voltage is rated at -100 V and continuous drain current at -38 A at TC = 25 °C.
3 S passive Source of the P-channel MOSFET; continuous source (diode conduction) current is rated at -50 A.
