DMP31D7L-7

Diodes Incorporated · MOSFETs · SOT-23

DMP31D7L-7 from Diodes Incorporated, in a SOT-23. 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 enhancement MOSFET, with an integrated gate protection diode (ESD protected gate); gate-source voltage is rated ±20 V (VGSS).
2 S passive Source of the MOSFET; body diode maximum continuous forward current is -0.52 A (IS) at TA=+25°C.
3 D passive Drain of the MOSFET; drain-source voltage is rated -30 V (VDSS) with maximum continuous drain current -0.58 A at TA=+25°C (VGS = -4.5 V, steady state).
