**MCC Micro Commercial Components** · MOSFETs · SOT-23

SI3415-TP from MCC Micro Commercial Components, 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 of the P-channel enhancement-mode MOSFET; the gate-source voltage rating is not legible in the extracted text, though gate-body leakage is specified at VGS = ±8 V. |
| 2 | SOURCE | passive | Source terminal of the P-channel MOSFET, the reference for VGS, in a device rated for a drain-source voltage of -20 V. |
| 3 | DRAIN | passive | Drain terminal of the P-channel MOSFET, rated for a drain-source voltage of -20 V and continuous drain current of -4.0 A. |
