ATM3401APSA

Agertech · MOSFETs · SOT-23

ATM3401APSA from Agertech, 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 of the P-channel MOSFET; gate-source voltage is rated ±12 V (absolute maximum) and the gate threshold VGS(th) is -0.7 V to -1.3 V at VDS=VGS, ID=-250µA.
2 S passive Source of the MOSFET, the reference terminal for VGS; the body diode forward voltage VSD is specified as -1.2 V max at IS=-4.2 A, VGS=0 V.
3 D passive Drain of the MOSFET; rated VDS -30 V, continuous drain current ID -4.2 A, pulsed drain current IDM -30 A, with RDS(ON) below 55 mΩ at VGS=-10 V.
