Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1 | passive | Protected line terminal 1, connected through a TVS diode to common pin 3; 3.3V reverse working voltage, 500W peak pulse (8/20us), ±30kV IEC 61000-4-2 ESD. |
| 2 | 2 | passive | Protected line terminal 2, connected through a TVS diode to common pin 3; 3.3V reverse working voltage, 500W peak pulse (8/20us), ±30kV IEC 61000-4-2 ESD. |
| 3 | 3 | passive | Common node of the two TVS diodes in the circuit diagram, shared with pins 1 and 2; the datasheet states the device protects one bidirectional line or two unidirectional lines. |
