DMX1072

ARK micro · MOSFETs · SOT-89

DMX1072 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; gate-to-source voltage rating is ±20 V, cut-off voltage VGS(OFF) is -3.3 V to -1.5 V (depletion mode, normally on), and gate-source ESD is 1500 V.
2 D passive Drain; drain-to-source voltage rating is 100 V, continuous drain current 0.3 A and pulsed 1.2 A.
3 S passive Source; the MOSFET current return terminal, with the body diode forward voltage of 1.5 V max at ISD=0.15 A.
