KO3415

KEXIN · MOSFETs · SOT-23

KO3415 from KEXIN, 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 of the P-channel MOSFET; the datasheet gives a gate-source voltage rating of VGS ±8 V.
2 Source passive Source of the P-channel MOSFET; the datasheet gives a drain-source voltage rating of VDS = -20 V.
3 Drain passive Drain of the P-channel MOSFET; the datasheet gives continuous drain current ID = -5 A at TA = 25°C (-4 A at TA = 70°C) and pulsed drain current IDM = -30 A.
