SI3139KE-TP-ES from ElecSuper, in a SOT-523. 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 P-channel MOSFET; gate-source voltage VGS is limited to ±12 V. |
| 2 | Source | passive | Source terminal of the P-channel MOSFET; the device is rated for a drain-source voltage BVDSS of -20 V. |
| 3 | Drain | passive | Drain terminal of the P-channel MOSFET; continuous drain current is -0.5 A at TA=25°C and -0.4 A at TA=75°C, with pulsed drain current IDM of -2.6 A. |
