PT2302B

PUOLOP · MOSFETs · SOT-23

PT2302B 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 limit is ±12V, with threshold VGS(th) of 0.6V at ID = 250uA.
2 S passive Source of the N-channel MOSFET; continuous drain current is 2.3A and pulsed drain current is 6A.
3 D passive Drain; drain-source voltage is rated at 20V, with RDS(on) below 50mΩ at VGS = 4.5V and ID = 2A.
