SI2302-TP from MCC Micro Commercial Components, 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 N-channel MOSFET; gate-source voltage is rated at 8 V maximum (VGS), and the gate threshold is 0.65 to 1.2 V at VGS = VDS, ID = 50 µA. |
| 2 | SOURCE | passive | Source of the N-channel MOSFET; body diode forward current is rated at 0.94 A with a forward voltage of 0.94 A test point at VGS = 0 V, IS = 0.94 A, and the source is the reference for the 8 V gate-source rating. |
| 3 | DRAIN | passive | Drain of the N-channel MOSFET; drain-source voltage is rated at 20 V and continuous drain current at 3 A, with pulsed drain current at 10 A. |
