PT2312

PUOLOP · MOSFETs · SOT-23

PT2312 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; the drawing shows it at the bottom-left of the package, with a gate-source voltage limit of ±8V and a threshold of 0.4V min to 1V max at 250uA.
2 S passive Source; the drawing shows it at the bottom-right of the package, with a maximum diode forward current of 1.7A.
3 D passive Drain; the drawing shows it as the single pin on the top side, rated for 20V drain-source voltage and 5.0A continuous drain current.
