DMG2305UX-13

Diodes Incorporated · MOSFETs · SOT-23

DMG2305UX-13 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; the top view shows it at the bottom-left, and the gate-source voltage is limited to ±8V with a threshold of -0.5V to -0.9V at ID = -250µA.
2 S passive Source of the P-channel MOSFET, shown at the bottom-right of the top view; drain-source voltage is rated at -20V.
3 D passive Drain, shown on the single top-side terminal in the top view; continuous drain current is -4.2A steady state at TA = +25°C and pulsed drain current is -15A.
