KAO3400

KUU · MOSFETs · SOT-23-3L

KAO3400 from KUU, in a SOT-23-3L. 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 GATE input Gate terminal; gate-source voltage is rated at ±12 V maximum, with threshold Vth(GS) of 0.7 V min, 0.9 V typ and 1.4 V max at ID=250 uA.
2 SOURCE passive Source terminal of the N-channel MOSFET, returned to ground in the switching test circuit.
3 DRAIN passive Drain terminal; drain-source voltage is rated at 30 V and continuous drain current at 5.8 A.
