KY2302H

KY · MOSFETs · SOT-23

KY2302H from KY, 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 is rated at ±12 V maximum.
2 SOURCE passive Source terminal of the N-channel MOSFET, the reference for VGS and the source side of the drain-source diode (VSD 1.3 V max at ISD=3 A).
3 DRAIN passive Drain terminal of the N-channel MOSFET; rated for 20 V drain-source voltage and 4 A continuous drain current.
