description
These low voltage dual symmetrical transient
voltage suppressor devices are designed to
protect ISDN applications against transients
caused by lightning strikes and a.c. power lines.
Offered in two voltage variants to meet battery
and protection requirements they are guaranteed
to suppress and withstand the listed international
lightning surges in both polarities. Transients are
initially clipped by breakdown clamping until the
voltage rises to the breakover level, which
causes the device to crowbar. The high crowbar
holding current prevents d.c. latchup as the
current subsides.

The small-outline 8-pin assignment has been carefully chosen for the TISP series to maximise the inter-pin
clearance and creepage distances which are used by standards (e.g. IEC950) to establish voltage withstand
ratings.

NOTES: 1. Further details on surge wave shapes are contained in the Applications Information section.
2. Initially the TISP must be in thermal equilibrium with 0C < T
J
<70C. The surge may be repeated after the TISP returns to its initial
conditions.
3. Above 70C, derate linearly to zero at 150C lead temperature.
NOTES: 4. These capacitance measurements employ a three terminal capacitance bridge incorporating a guard circuit. The third terminal is
connected to the guard terminal of the bridge.
5. Further details on capacitance are given in the Applications Information section.
