DESD3Z3V3

CBI · ESD And Surge Protection (TVS/ESD) · SOD-323

DESD3Z3V3 from CBI, in a SOD-323. 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 One terminal of the bi-directional ESD protection diode for one line, with 3.3V reverse stand-off voltage; the device is bi-directional so polarity is not specified.
2 2 passive Other terminal of the bi-directional ESD protection diode for one line, with 3.3V reverse stand-off voltage; the device is bi-directional so polarity is not specified.
