SI2302 2.5A

YONGYUTAI · MOSFETs · SOT-23

SI2302 2.5A from YONGYUTAI, 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 GATE input Gate of the N-channel MOSFET; gate-source voltage is rated ±12 V maximum, with threshold Vth(GS) of 0.5 V min, 0.75 V typ, 1.2 V max at ID=250 uA.
2 SOURCE passive Source of the N-channel MOSFET; the diode forward current is rated 2.0 A max.
3 DRAIN passive Drain of the N-channel MOSFET; drain-source voltage is rated 20 V maximum and drain current 2.5 A.
