ESD5302F-3

WILLSEMI Will Semicon · ESD And Surge Protection (TVS/ESD) · SOT-23

ESD5302F-3 from WILLSEMI Will Semicon, 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 I/O1 bidirectional Protected data line with 5V maximum stand-off voltage, providing ±20kV contact and air ESD protection per IEC61000-4-2 and 4A (8/20µs) surge capability per IEC61000-4-5.
2 I/O2 bidirectional Protected data line with 5V maximum stand-off voltage, providing ±20kV contact and air ESD protection per IEC61000-4-2 and 4A (8/20µs) surge capability per IEC61000-4-5.
3 GND power_in Common ground reference for the two steering diode pairs and the TVS diode of the array.
