The electrical characteristics of a thyristor overvoltage protector are strongly dependent on junction
temperature, T
measurement. The values given in this data sheet were measured on commercial testers, which generally
minimise the temperature rise caused by testing.
This section covers three topics. Firstly, it is explained why gated protectors are needed. Second, the
performance of the original IC (integrated circuit) based version is described. Third, the performance
improvements given by the TISP61060 are detailed.
Fixed voltage thyristor overvoltage protectors have been used since the early 1980s to protect monolithic
SLICs (Subscriber Line Interface Circuits) against overvoltages on the telephone line caused by lightning, a.c.
power contact and induction. As the SLIC was usually powered from a fixed voltage negative supply rail, the
limiting voltage of the protector could also be a fixed value. The TISP1072F3 is a typical example of a fixed
voltage SLIC protector.
SLICs have become more sophisticated. To minimise power consumption, some designs automatically adjust
the supply voltage, V
supply voltage would be set low, but for long lines, a higher supply voltage would be generated to drive
sufficient line current. The optimum protection for this type of SLIC would be given by a protection voltage
which tracks the SLIC supply voltage. This can be achieved by connecting the protection thyristor gate to the
SLIC supply, Figure 2. This gated (programmable) protection arrangement minimises the voltage stress on
the SLIC, no matter what value of supply voltage.
