Power Line Protection

During fault, the only circuit breaker closest to the fault point should be tripped. The operating time of relay associated with protection of line should be as minimum as possible in order to prevent unnecessary tripping of circuit breakers associated with other healthy parts of power system.

No

Clamping Voltage

32.2 V

Peak Pulse Current

The peak pulse power rating of a TVS diode is defined as the instantaneous power dissipated by a device for a given pulse condition, and is a measure of the power that is dissipated in the TVS junction during a given transient event.

12.4 A

Max Surge Current

Surge current is a peak non repetitive current. Maximum (peak or surge) forward current = IFSM or if(surge), the maximum peak amount of current the diode is able to conduct in forward bias mode.
