CDSOD323-T03S
BOURNS · ESD And Surge Protection (TVS/ESD) · SOD-323
CDSOD323-T03S 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 CDSOD323-T03S TVS diode, rated for a 3.3 V working peak voltage (VM), 4.0 V minimum breakdown at 1 mA, and 125 µA maximum leakage at VWM; the datasheet does not state whether this pin is the cathode. |
| 2 | 2 | passive | Terminal 2 of the unidirectional CDSOD323-T03S TVS diode, rated for a 3.3 V working peak voltage (VM), 4.0 V minimum breakdown at 1 mA, and 125 µA maximum leakage at VWM; the datasheet does not state whether this pin is the anode. |
