Thyristor TSPD 160V 60A 2-Pin SMB T/R
Manufacturer Part #: TISP4A270H3BJR-S
Alternate Part #: TISP4A270H3BJR-S
It is an asymmetrical-bidirectional thyristor surge protective device (SPD). It is designed to limit the peak voltages on the RLINE (Ring Line) terminal of ‘7581/2/3 LCAS (Line Card Access Switch) devices. The voltages are chosen to give RLINE terminal protection for all LCAS switch conditions. The most potentially stressful condition is low level power cross when the switches are closed. Under this condition, it limits the voltage and corresponding LCAS dissipation until the LCAS thermal trip operates and opens the switchesThis high current protection device is in a plastic SMB package (JEDEC DO-214AA) and supplied in embossed tape reel pack.
