CDSOT23-T12C

BOURNS · ESD And Surge Protection (TVS/ESD) · SOT-23

CDSOT23-T12C from BOURNS, 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 1 passive Bidirectional TVS line terminal 1 (anode/cathode side of one diode), connected through a TVS diode to common pin 3, with 12 V max working peak voltage (VWM) and 13.3 V min breakdown at 1 mA.
2 2 passive Bidirectional TVS line terminal 2 (second protected line), connected through a TVS diode to common pin 3, with 12 V max working peak voltage (VWM) and 13.3 V min breakdown at 1 mA.
3 3 passive Common node joining the two back-to-back TVS diodes of the bidirectional CDSOT23-T12C, shared between pins 1 and 2.
