SI2309S from BORN, in a SOT-23-3L. 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 of the P-channel MOSFET, with a maximum gate-source voltage of ±20 V and a gate threshold voltage of -1.0 V min to -3 V max at ID = -250 uA. |
| 2 | S | passive | Source of the P-channel MOSFET, where the body diode forward voltage is -1.2 V max at IS = -1.2 A. |
| 3 | D | passive | Drain of the P-channel MOSFET, rated for -60 V drain-source voltage and -1.9 A continuous drain current at TA = 25 °C. |
