CDSOD323-T03

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

CDSOD323-T03 from BOURNS, 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 Terminal 1 of the unidirectional TVS diode (the cathode end, marked by the polarity band), connected to the protected line with a 3.3 V working peak voltage and 4.0 V minimum breakdown at 1 mA.
2 2 passive Terminal 2 of the unidirectional TVS diode (the anode end), normally returned to ground, with a 7.0 V maximum clamping voltage at IP = 1 A.
