JSM3400

JSMSEMI · MOSFETs · SOT-23

JSM3400 from JSMSEMI, 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 limited to ±12 V absolute maximum, with threshold VGS(th) of 0.7 V min to 1.4 V max at ID=250µA.
2 S passive Source; body diode runs from source to drain, with forward drop VSD of 1 V max at IS=1A.
3 D passive Drain; drain-source voltage rated 30 V maximum and continuous drain current 5.8 A.
