SI2310AI-MS

MSKSEMI · MOSFETs · SOT-23

SI2310AI-MS from MSKSEMI, 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; VGS is limited to ±20 V per the absolute maximum ratings, and the device is specified for gate drive as low as 4.5 V.
2 D passive Drain terminal; VDS is rated up to 60 V and continuous drain current is rated at 3 A.
3 S passive Source terminal; it is the reference for VGS and the body diode forward current is rated at 3 A.
