DMG301NU-7

Diodes Incorporated · MOSFETs · SOT-23

DMG301NU-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 (>6kV HBM) through an internal gate protection diode, with VGSS of 8V max and gate threshold of 0.7V to 1.1V at ID = 250µA.
2 S passive Source terminal of the N-channel MOSFET, with maximum body diode continuous current IS of 0.5A.
3 D passive Drain terminal of the N-channel MOSFET, with VDSS of 25V and continuous drain current of 0.26A at VGS = 4.5V, TA = +25°C.
