BRCS3401MCQ

Foshan Blue Rocket Elec · MOSFETs · SOT-23-3

BRCS3401MCQ from Foshan Blue Rocket Elec, in a SOT-23-3. 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 of the P-channel MOSFET; gate-source voltage is rated at ±12 V (absolute maximum).
2 S passive Source of the P-channel MOSFET; the datasheet gives no separate pin-level limit, and the body diode forward voltage is specified source-to-drain (VSD -1.0 V max at IS = -1 A).
3 D passive Drain of the P-channel MOSFET; rated at VDS = -30 V with continuous drain current ID = -4.2 A at TA = 25 °C.
