CDSOT23-T24 from BOURNS, in a SOT-23-3. 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 | Protected line input tied internally to pin 2 in the unidirectional T24 schematic, with a 24 V maximum working peak voltage (VWM) and 26.7 V minimum breakdown at 1 mA. |
| 2 | 2 | passive | Second protected line input tied internally to pin 1 in the unidirectional T24 schematic, with a 24 V maximum working peak voltage (VWM) and 26.7 V minimum breakdown at 1 mA. |
| 3 | 3 | passive | Common terminal of the TVS diode, shown on the datasheet schematic as the opposite side of the diode from pins 1 and 2; the datasheet does not label it as ground. |
