FEATURES
SO-8 WIDE
The LCP02-150B1 has been developed to protect
SLICs operating on both negative and positive bat-
tery supplies, as well as on high voltage SLICs. It
provides crowbar mode protection for both TIP and
RING lines. The surge suppression is assumed for
each wire by two thyristor structures, one dedi-
cated to positive surges the second one for nega-
tive 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-V0 resin
approved
