| Silicon Avalanche Diodes Axial Leaded Telecommunications Transient Voltage Suppressors FOLDBAKTM SERIES 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 * Foldback characteristics * 2200 watts Peak Power rated with 10/1000S pulse * 30,000 watts Peak Pulse Power based on 8/20S * UL 94V-0 flammability classification 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.
