ASYMMETRICAL-BIDIRECTIONAL THYRISTOR SPD
Description
The TISP4A270H3BJ is an asymmetrical-bidirectional thyristor surge protective device (SPD). It is designed to limit the peak voltages on the
R
(Ring Line) terminal of ‘7581/2/3 LCAS (Line Card Access Switch) devices. The TISP4A270H3BJ must have the bar-indexed terminal 1 (G)
connected to the protective ground and terminal 2 (R) connected to the R
LINE
terminal.

The TISP4A270H3BJ voltages are chosen to give R
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, the TISP4A270H3BJ limits the voltage and
corresponding LCAS dissipation until the LCAS thermal trip operates and opens the switches.
Under open-circuit ringing conditions, the R
terminal will have high peak voltages. For battery backed ringing, the R
terminal will have a
larger peak negative voltage than positive, i.e. the peak voltages are asymmetric. The TISP4A270H3BJ has a similar voltage asymmetry which
will allow the maximum possible ringing voltage, while still giving protection. With a connected telephone line, the LCAS T
(Tip Line)
terminal voltage levels will be less than 50 % of the open-circuit R
LINE
terminal values. So the T
LINE
terminal can be protected by a symmetrical-
bidirectional overvoltage protector of the TISP4xxxH3BJ series.
