CAN series surge protective devices (SPD) are manufactured while using multi-stage protection circuits. They are used to protect CAN interface communication circuits. A gas-filled surge arrester is used in the circuits as a rough protection, while a transient voltage suppressor (TVS) is used as the thin protection element, as well as in some versions of Bourns transient blocking unit (TBU) from (USA).
The current solution allows to achieve a high diverting ability, a sufficiently low threshold for the protection (surge protective devices operating voltage) and a high response speed. The current protection stages together with isolation elements can be placed in a single compact body, mounted on 18 or 36 mm wide DIN rail, given the relatively low discharge currents values (when compared with power supply circuits).
The surge protective devices (SPD) data are connected in CAN series interface circuit. Besides it’s worth mentioning the protective circuit takes into account both permissible impulse effects levels on the protected equipment as well as the protected circuits and CAN interface internal features, including rated current of 0.5 A, a rated voltage of 6 V and a transmission speed of up to 1 Mbps. TVS diodes provide dissipation up to 1500 watts of pulsed power. There is a chance to connect both shielded and non-shielded two-wire differential CAN interface lines. The current device is available in the versions with the ability to connect either 1 or 2 interface lines.
