SI2306 from Guangdong Hottech, 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, with gate-source voltage rated at 20 V (VGS ±20 V) per the absolute maximum ratings. |
| 2 | Source | passive | Source terminal of the N-channel MOSFET; the source-drain diode forward voltage is 0.8 V typical and 1.2 V maximum at IS = 1.25 A, VGS = 0 V. |
| 3 | Drain | passive | Drain terminal of the N-channel MOSFET, rated for 30 V drain-source voltage and 3.16 A continuous drain current (10 A pulsed). |
