DESCRIPTION

The LCP02-150B1 has been developed to protect
SLICsoperatingonboth negativeand positivebat­tery supplies, as well as on high voltage SLICs. It
providescrowbar modeprotection for bothTIP and
RINGlines. Thesurge suppression isassumed for
each wire by two thyristor structures, one dedi­cated to positive surges the second one for nega­tive surges. Both positive and negative threshold
levels are programmable by two gates (Gn and
Gp). The use of transistors decreases the battery
currents during surge suppression.
The LCP02-150B1 has high Bellcore Core, ITU-T
and FCC Part 68 lightning surge ratings, ensuring
rugged performance in the field. In addition, it is
also specified to assist a designer to comply with
UL1950, IEC950 and CSA C22.2. It is UL 497B
approved (file E136224), and has UL94-V0resin
approved
