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. |
