SI2310A

UMW · MOSFETs · SOT-23

SI2310A from UMW, 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 terminal of the N-channel MOSFET; gate-source voltage is rated at ±20 V in the absolute maximum ratings.
2 S passive SOURCE terminal of the N-channel MOSFET; the reference for VGS, and the datasheet gives no separate pin-level limit for it.
3 D passive DRAIN terminal of the N-channel MOSFET; drain-source voltage is rated at 60 V and continuous drain current at 3 A (TA = 25°C).
