KO3416

KEXIN · MOSFETs · SOT-23-3

KO3416 from KEXIN, in a SOT-23-3. 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 terminal of the N-channel enhancement MOSFET; gate-source voltage is rated ±8 V (VGS) per the absolute maximum ratings.
2 S passive Source terminal of the N-channel MOSFET; the body diode maximum continuous current IS is 2 A.
3 D passive Drain terminal of the N-channel MOSFET; drain-source voltage VDS is rated 20 V with continuous drain current ID of 6.5 A at Ta=25°C.
