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

SI2306-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 N-channel MOSFET; the datasheet rates gate-source voltage VGS at ±20 V. |
| 2 | SOURCE | passive | Source terminal of the N-channel MOSFET; the datasheet gives source current IS as a maximum rating for this device. |
| 3 | DRAIN | passive | Drain terminal of the N-channel MOSFET; the datasheet rates drain-source voltage VDS at 30 V and continuous drain current at 3.16 A. |
