HL3402

hongjiacheng · MOSFETs · SOT-23

HL3402 from hongjiacheng, 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 of the N-channel MOSFET; gate-source voltage is rated at ±12 V (VGS) with a 0.65 V to 1.5 V threshold.
2 S passive Source of the N-channel MOSFET, the reference for the gate-source voltage; the device is rated 30 V VDS.
3 D passive Drain of the N-channel MOSFET, rated 30 V VDS with 2.5 A continuous drain current at TA=25℃ and 16 A pulsed drain current.
