**Foshan Blue Rocket Elec** · MOSFETs · SOT-323

BRCS3134WA from Foshan Blue Rocket Elec, 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 | G | input | Gate terminal of the N-channel MOSFET, with gate-source voltage limited to ±8 V and ESD protection up to 2 kV. |
| 2 | S | passive | Source terminal of the N-channel MOSFET; the datasheet gives no separate pin-level limit for it beyond the device absolute maximum ratings (VDSS 20 V, ID 0.75 A continuous). |
| 3 | D | passive | Drain terminal of the N-channel MOSFET, rated for a drain-source voltage of 20 V and continuous drain current of 0.75 A. |
