Silicon Avalanche Diodes

Axial Leaded Telecommunications Transient Voltage Suppressors

FOLDBAK

Designed to protect sensitive telecommunications electronics from

transients which originate from induced lightning, power cross

and inductive load switching etc., especially where breakover

devices would cause nuisance latch-up.

Typical equipment would be: line cards, PABX, modems,

multiplexers and NTDs.

FEATURES

DESCRIPTION

The foldback characteristic of this device eliminates the clamping

of the DC current, or the battery, used in telecom systems, so

latch-up is eliminated. Latch-up can occur with breakover devices

due to the conduction follow-on current supplied by the DC

system, after the device has responded to a transient.

With breakover devices, latch-up will happen more readily as the

ambient temperature rises because the holding current values will

fall with rising temperature.

The Foldbak eliminates this problem while still providing high

levels of protection.
