CDSOD323-T05S 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 two TVS diode terminals; for the unidirectional CDSOD323-T05S the cathode is marked by the polarity band, but the datasheet does not state whether pin 1 is the cathode, with working peak voltage VM 5.0 V and minimum breakdown VBR 6.0 V at 1 mA. |
| 2 | 2 | passive | The other TVS diode terminal; for the bidirectional CDSOD323-T05SC both terminals are interchangeable and the electrical limits apply in both directions, while the datasheet does not state whether pin 2 is the anode for the unidirectional T05S, with maximum clamping voltage 9.8 V at IP = 1 A. |
