DMX4022E

ARK micro · MOSFETs · SOT-89

DMX4022E from ARK micro, in a SOT-89. 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; depletion-mode device is normally on at VGS=0V, gate-to-source cut-off voltage VGS(OFF) is -3.3V to -1.5V and the absolute maximum VGS is ±20V.
2 D passive Drain; drain-to-source voltage rating VDSX is 400V and continuous drain current is 0.20A for the SOT-89 part.
3 S passive Source; current return terminal of the N-channel depletion-mode MOSFET, with gate-to-source ESD rating of 3000V (HBM).
