PT3402

PUOLOP · MOSFETs · SOT-23

PT3402 from PUOLOP, 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; gate-source voltage is rated ±12 V max, with VGS(th) 0.6 to 1.4 V and RDS(ON) specified down to VGS = 2.5 V.
2 S passive Source; continuous drain current is 4 A at TA=25°C and the body-diode continuous current is 2.5 A max.
3 D passive Drain; drain-source voltage is rated 30 V max, with 15 A pulsed drain current.
