BRCS3420MC

Foshan Blue Rocket Elec · MOSFETs · SOT-23

BRCS3420MC from Foshan Blue Rocket Elec, 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 G input Gate terminal of the N-channel MOSFET; the absolute maximum gate-source voltage is ±12 V and the gate threshold voltage VGS(th) is 0.5 V to 1 V.
2 S passive Source terminal of the N-channel MOSFET; the body diode forward voltage VSD is 0.75 V typical and 1 V maximum at IS = 1 A.
3 D passive Drain terminal of the N-channel MOSFET; the drain-source breakdown voltage BVDSS is 20 V minimum and the continuous drain current is 6 A at Ta = 25 ℃.
