DMN3730U-7

Diodes Incorporated · MOSFETs · SOT-23

DMN3730U-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, ESD protected to 2kV via an internal gate protection diode, with VGS(TH) of 0.45V to 0.95V at ID = 250μA and a maximum VGSS of ±8V.
2 S passive Source terminal of the N-channel MOSFET, connected to the body diode, with continuous drain current up to 0.94A at TA = +25°C.
3 D passive Drain terminal of the N-channel MOSFET, rated for a maximum drain-source voltage VDSS of 30V and pulsed drain current IDM of 10A.
