YONGYUTAI · MOSFETs · SOT-23
SI2305 2305 from YONGYUTAI, 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; the datasheet limits the gate-source voltage VGSS to ±8 V. |
| 2 | SOURCE | passive | Source terminal of the P-channel MOSFET; the datasheet gives no pin-specific rating and lists the drain-source voltage VDSS as -12 V for the device. |
| 3 | DRAIN | passive | Drain terminal of the P-channel MOSFET; the datasheet gives no pin-specific rating and lists the continuous drain current as -4.2 A at TA=25℃. |
