Description

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-10TM 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.
