Description

The foldback characteristic of this FB120 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 FB120, latch-up will happen more readily as the ambient temperature rises because the holding current values will fall with rising temperature.

The FB120 Foldbak eliminates this problem while still providing high levels of protection.
