SI3099-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 | MOSFET gate; gate-source voltage is rated at ±12 V (VGS). |
| 2 | SOURCE | passive | MOSFET source; the reference terminal for VGS, with drain-source voltage rated at 30 V (VDS). |
| 3 | DRAIN | passive | MOSFET drain; continuous drain current is 1.1 A at TA=25°C, with pulsed drain current rated at 4.4 A. |
