BOURNS · ESD And Surge Protection (TVS/ESD) · SOT-23
CDSOT23-T03C 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 | I/O 1 | passive | Bidirectional TVS channel terminal connected through one diode to common pin 3, protecting a line against ESD and surge with VWM 3.3 V (CDSOT23-T03C). |
| 2 | I/O 2 | passive | Bidirectional TVS channel terminal connected through the second diode to common pin 3, protecting a second line with VWM 3.3 V and 6.0 V min breakdown at 1 mA. |
| 3 | COMMON | passive | Common node of the two back-to-back TVS diodes in the bidirectional configuration, shared by pins 1 and 2 (typically referenced to ground). |
