DMN2055UW-13

Diodes Incorporated · MOSFETs · SOT-323

DMN2055UW-13 from Diodes Incorporated, in a SOT-323. 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 of the N-channel MOSFET; gate-source voltage VGSS is limited to ±8 V and gate threshold VGS(TH) is 0.4 V min to 1.0 V max.
2 S passive Source of the N-channel MOSFET; the maximum body diode forward current IS is 0.8 A.
3 D passive Drain of the N-channel MOSFET; drain-source voltage VDSS is 20 V and continuous drain current ID is 3.1 A at TA = +25°C (steady state, VGS = 4.5 V).
