SI2347DS-T1-GE3-VB from VBsemi Elec, in a SOT-23(TO-236). 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; gate-source voltage limit is ±20 V, with threshold VGS(th) of -0.5 to -2.0 V at ID = -250 µA. |
| 2 | S | passive | Source of the P-channel MOSFET; continuous source-drain diode current is -2.1 A at TC = 25 °C. |
| 3 | D | passive | Drain; drain-source voltage is -30 V, with RDS(on) of 0.046 Ω at VGS = -10 V and continuous ID of -5.6 A at TC = 25 °C. |
