Providing \u00b121 kV ESD per IEC 61000-4-2 and 3A surge capability, it safeguards CAN transceivers from transient threats. The low 12 pF capacitance preserves signal integrity at CAN FD data rates up to 5 Mbps. AEC-Q101 qualified and bidirectional, designed for 12V\/24V automotive CAN systems.","working_principle":"Bidirectional TVS diodes are connected between CAN bus lines and ground. Under normal operation, the TVS presents high impedance with only 0.02 \u00b5A leakage. When a transient exceeds the breakdown voltage (26.7V min), the TVS rapidly clamps to a safe level (33V @ 1A), diverting surge current away from the protected transceiver.","pin_description":"
