BL758L INTEGRATED SYMMETRICAL AND ASYMMETRICAL BIDIRECTIONAL OVERVOLTAGE PROTECTORS

The TISPL758LF3 is an integrated combination of a symmetrical bidirectional overvoltage protector and an asymmetrical bidirectional overvoltage protector. It is designed to limit the peak voltages on the line terminals of the Lucent Technologies L7581/2/3 LCAS (Line Card Access Switches). An LCAS may also be referred to as a Solid State Relay, SSR, i.e. a re.

Under this condition, the TISPL758LF3D limits the voltage and corresponding LCAS dissipation until the LCAS thermal trip operates and opens the switches. Under open-circuit ringing conditions, the line ring (R) conductor will have high peak voltages. For battery backed ringing, the ring conductor will have a larger peak negative voltage than positive i.e.
