SRV05-4.TCT from SEMTECH, in a SOT-23-6L. 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 Line 1 | bidirectional | Protected data line 1; connected to external signal line for ESD/EFT/lightning transient protection via clamping to ground or positive reference. |
| 2 | REF1/GND | power_in | Negative reference/ground connection; provides return path for transient current and TVS diode biasing; should connect directly to board ground plane. |
| 3 | I/O Line 2 | bidirectional | Protected data line 2; connected to external signal line for ESD/EFT/lightning transient protection via clamping to ground or positive reference. |
| 4 | I/O Line 3 | bidirectional | Protected data line 3; connected to external signal line for ESD/EFT/lightning transient protection via clamping to ground or positive reference. |
| 5 | REF2/VCC | power_in | Positive reference/VCC connection; biases internal TVS diode, typically connected to positive supply rail or through 100kΩ resistor or left unconnected for isolated operation. |
| 6 | I/O Line 4 | bidirectional | Protected data line 4; connected to external signal line for ESD/EFT/lightning transient protection via clamping to ground or positive reference. |
