Description

The LCP03 has been developed to protect SLICs

operating on both negative and positive battery

supplies. It provides crowbar mode protection for

both TIP and RING lines. The surge suppression

is assumed for each wire by two thyristor

structures, one dedicated to positive surges the

second one for negative surges.

LCP03 can be used to help equipment to meet

various standards such as UL1950, IEC 60950 /

CSAC22.2, UL1459 and TIA-968-A (formerly FCC

part68). A Trisil™ meets UL94 V0. (Trisils are

UL497B approved - file: E136224).
