3400N-MS

MSKSEMI · MOSFETs · SOT-89

3400N-MS from MSKSEMI, in a SOT-89. 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 of the N-channel MOSFET, with a Gate-Source voltage rating of ±12 V and a threshold of 0.5 to 1.4 V at ID=250μA.
2 D passive Drain of the N-channel MOSFET (also the exposed tab), rated 30 V Drain-Source with 7.0 A continuous current at TA=25℃.
3 S passive Source of the N-channel MOSFET, carrying the 7.0 A continuous drain-source current and body-diode current at TA=25℃.
