FEATURES
PowerS0-10TM
The LCP02-150M has been developed to protect
SLICs operating on both negative and positive
supplies, as well as on high voltage SLICs. It
provides crowbar mode protection for both TIP and
RING lines. Surge suppression is assumed for
each wire by two thyristor structures, one
dedicated to positive surges, the second one to
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 LCP02-150M has high Bellcore Core, ITU-T
and FCC Part 68 lightning surge ratings, ensuring
rugged performance in the field.
The choice of the PowerSo-10
TM
package is
driven by its high power dissipation capability.
In addition, the LCP02-150M 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
