MEM2303M3G

MICRONE · MOSFETs · SOT-23

MEM2303M3G from MICRONE, 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; gate-source voltage limited to ±12 V, with a threshold of -0.7 to -1.3 V at ID=-250uA.
2 S passive Source; maximum body-diode continuous current is -2.2 A and drain current is -4.2 A at TA=25℃.
3 D passive Drain; drain-source voltage rated -30 V with pulsed drain current of -30 A.
