SI3139KA-TP from MCC Micro Commercial Components, in a SOT-723. 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 of the P-channel MOSFET, rated for low logic level gate drive; the datasheet's maximum ratings table lists gate-source voltage as ±12 V. |
| 2 | SOURCE | passive | Source of the P-channel MOSFET; the datasheet gives the device drain-source voltage as -20 V, continuous drain current as -0.66 A, and pulsed drain current IDM as -1.2 A. |
| 3 | DRAIN | passive | Drain of the P-channel MOSFET; the device is rated for a drain-source breakdown voltage V(BR)DSS of -20 V and power dissipation PD of 0.15 W. |
