SKML2803

Shikues · MOSFETs · SOT-23

SKML2803 from Shikues, 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 GATE input Gate terminal of the N-channel MOSFET; gate-source voltage limited to ±20 V with threshold of 1 V min, 1.4 V typ, 3 V max at ID=250 uA.
2 SOURCE passive Source terminal of the N-channel MOSFET; body diode forward current up to 1.7 A.
3 DRAIN passive Drain terminal of the N-channel MOSFET; drain-source voltage rated 30 V and drain current 4.5 A.
