MCC Micro Commercial Components · MOSFETs · SOT-23
SI2312A-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 ±8 V. |
| 2 | SOURCE | passive | Source terminal of the N-channel MOSFET; the datasheet rates drain-source voltage VDS at 20 V. |
| 3 | DRAIN | passive | Drain terminal of the N-channel MOSFET; the datasheet gives a repetitive pulsed drain current rating of 20 A (pulse width limited by maximum junction temperature). |
