# CDSOD323-T05LC

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

CDSOD323-T05LC 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 | One of the two terminals of the bidirectional TVS diode (CDSOD323-T05LC, working peak voltage VM 5.0 V); the electrical specifications apply in both directions, so there is no polarity requirement. |
| 2 | 2 | passive | The second terminal of the bidirectional TVS diode (CDSOD323-T05LC, working peak voltage VM 5.0 V); the electrical specifications apply in both directions, so there is no polarity requirement. |
