TISP3260F3

These high voltage dual symmetrical transient voltage suppressor devices TISP3260F3 are designed to protect telecommunication applications with ground backed ringing against transients caused by lightning strikes and a.c. power lines. Offered in five 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.

These monolithic protection devices TISP3260F3 are fabricated in ion-implanted planar structures toensure precise and matched breakover control and are virtually transparent to the system in normal operation

The small-outline 8 pin assignment TISP3260F3 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.
