SM2302SRL-HXY from HXY MOSFET, 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 | G | input | Gate terminal; gate-source voltage is limited to ±12 V (absolute maximum), and RDS(ON) is specified at VGS = 2.5 V and 4.5 V. |
| 2 | D | passive | Drain terminal; drain-source voltage is rated at 20 V maximum with continuous drain current of 2.8 A. |
| 3 | S | passive | Source terminal; the body diode forward current is rated at 3.3 A maximum, and VGS is referenced to this pin. |
