BSS138BK-HXY

HXY MOSFET · MOSFETs · SOT-23

BSS138BK-HXY from HXY MOSFET, 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 enhancement-mode MOSFET, with VGS rated ±20 V and a threshold VGS(th) of 0.8 V min to 1.5 V max at ID = 1 mA.
2 S passive Source of the N-channel MOSFET, with the body diode running from source to drain (VSD max 1.4 V at IS = 0.44 A).
3 D passive Drain of the N-channel MOSFET, rated at VDS = 50 V and ID = 0.22 A continuous at TA = 25 °C (0.88 A pulsed).
