TRIPLE BIDIRECTIONAL THYRISTOR OVERVOLTAGE PROTECTORS
MARCH 1994 - REVISED MARCH 2000
Each terminal pair has a symmetrical voltage-triggered thyristor characteristic. Overvoltages are initially
clipped by breakdown clamping until the voltage rises to the breakover level, which causes the device to
crowbar into a low-voltage on state. This low-voltage on state causes the current resulting from the
overvoltage to be safely diverted through the device. The high crowbar holding current prevents d.c. latchup
as the diverted current subsides.These protectors are guaranteed to voltage limit and withstand the listed
lightning surges in both polarities.
These medium and high voltage devices are offered in nine voltage variants to meet a range battery and
ringing voltage requirements. They are guaranteed to suppress and withstand the listed international lightning
surges on any terminal pair. Similar devices with working voltages of 58 V and 66 V are detailed in the
TISP7072F3, TISP7082F3 data sheet.

NOTES: 1. Initially the TISP® must be in thermal equilibrium at the specified TA. The surge may be repeated after the TISP® returns to its
initial conditions. The rated current values may be applied singly either to the R to G or to the T to G or to the T to R terminals.
Additionally, both R to G and T to G may have their rated current values applied simultaneously (In this case the total G terminal
current will be twice the above rated current values).

3. Above 70 °C, derate ITSM linearly to zero at 150 °C lead temperature.
