DMG2302UQ-7

Diodes Incorporated · MOSFETs · SOT-23

DMG2302UQ-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; controls the channel, with an absolute maximum gate-source voltage of ±8V and a threshold of 0.4V to 1.0V at ID = 50μA.
2 S passive Source terminal of the N-channel MOSFET, with the body diode anode attached.
3 D passive Drain terminal; drain-source voltage is rated to 20V and continuous drain current to 4.2A at TA = +25°C.
