AO3400A-MS

MSKSEMI · MOSFETs · SOT-23

AO3400A-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; gate-source voltage limit is ±12 V and the device suits 2.5 V gate drive applications.
2 S passive Source terminal of the N-channel MOSFET.
3 D passive Drain; drain-source voltage rating is 30 V and continuous drain current is 5.8 A at TA=25℃.
