DMG3406L-7

Diodes Incorporated · MOSFETs · SOT-23

DMG3406L-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 rated ±20 V maximum and a threshold of 1.0 to 2.0 V at ID = 250μA.
2 S passive Source; the pin diagram shows it at bottom right, and the body diode carries up to 1.4 A forward current.
3 D passive Drain; the single top pin, rated 30 V VDSS and 3.6 A continuous at TA = +25°C (VGS = 10V).
