RC3401

RealChip · MOSFETs · SOT-23-3

RC3401 from RealChip, 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 Gate input MOSFET gate terminal; the datasheet rates the gate-source voltage VGS at ±12 V.
2 Source passive MOSFET source terminal; the body-diode maximum continuous current IS is rated at -2.2 A.
3 Drain passive MOSFET drain terminal; rated for a drain-source voltage VDS of -30 V and a continuous drain current ID of -4.2 A at Ta = 25℃.
