DMN53D0U-7

Diodes Incorporated · MOSFETs · SOT-23

DMN53D0U-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 via an internal gate protection diode, with a gate-source rating of ±12 V and a threshold of 0.4 V to 1.0 V at 250 µA.
2 S passive Source terminal of the N-channel MOSFET, with the body diode running to the drain (VSD max 1.4 V at IS = 115 mA).
3 D passive Drain terminal of the N-channel MOSFET, rated 50 V VDSS and 300 mA continuous (500 mA pulsed) drain current.
