HDESD3V3S1BL-7B-71

HXY MOSFET · Electrostatic And Surge Protection (TVS/ESD) · DFN1006-2L

HDESD3V3S1BL-7B-71 from HXY MOSFET, in a DFN1006-2L. 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 1 passive Bi-directional ESD protection terminal (I/O line) with 3.3V reverse working voltage, protecting one I/O line; the datasheet shows pins 1 and 2 without names.
2 2 passive Second terminal of the bi-directional ESD protection diode (connect to ground or the other side of the protected line); the datasheet shows pins 1 and 2 without names.
