KI2300

KEXIN · MOSFETs · SOT-23

KI2300 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 terminal of the N-channel enhancement MOSFET, with a gate-source voltage rating of ±10 V (VGS).
2 Source passive Source terminal of the N-channel enhancement MOSFET; the datasheet gives no pin-specific voltage or current limit for this terminal.
3 Drain passive Drain terminal of the N-channel enhancement MOSFET, rated for a drain-source voltage of 20 V and a continuous drain current of 5.0 A.
