DMG3414U-7

Diodes Incorporated · MOSFETs · SOT-23

DMG3414U-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 VGS limited to ±8V and threshold VGS(TH) of 0.5V to 0.9V at ID = 250µA.
2 S passive Source terminal of the N-channel MOSFET; continuous drain current is 4.2A at TA = +25°C.
3 D passive Drain terminal; drain-source voltage rated at 20V (VDSS) with pulsed drain current of 30A.
