**MCC Micro Commercial Components** · MOSFETs · SOT-323

SI3134KWA-TP from MCC Micro Commercial Components, in a SOT-323. 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 N-channel MOSFET; gate-source voltage limited to ±12 V with a typical threshold of 0.75 V (VDS=VGS, ID=250µA), driven at low logic level (RDS(on) specified at VGS 1.8 V to 4.5 V). |
| 2 | SOURCE | passive | Source of the N-channel MOSFET, with the body diode anode here; continuous drain current is 0.75 A and the diode forward voltage is at most 1.2 V at IS=500mA. |
| 3 | DRAIN | passive | Drain of the N-channel MOSFET; drain-source voltage is rated 20 V, continuous drain current 0.75 A and pulsed drain current 3.0 A. |
