CDSOD323-T12C

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

CDSOD323-T12C 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 Bidirectional TVS terminal 1 (CDSOD323-T12C, 12 V VWM, 13.3 V min breakdown at 1 mA, 19.0 V max clamping at 1 A); electrical specifications apply in both directions, no cathode band on bidirectional parts.
2 2 passive Bidirectional TVS terminal 2 (CDSOD323-T12C, 12 V VWM, 1 µA max leakage at VWM); interchangeable with pin 1 since the device protects one line or I/O port in both polarities.
