Features
• Protection IC recommended for ringing SLICs
• Wide firing voltage range: -120 V to +120 V
• Low gate triggering current: IG = 5 mA max
• Peak pulse current: IPP = 30 A (10/1000 μs)
• Holding current: IH = 150 mA min.

Description
The LCP02 has been developed to protect SLICs
operating on both negative and positive battery
supplies, as well as 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 dedicated to positive surges the second one
for negative surges. Both positive and negative
threshold levels are programmable by two gates.
LCP02 can be used to help equipment to meet
various standards such as UL1950, IEC 60950 /
CSAC22.2, UL1459 and TIA-968-A. LCP02
pinout and clearance is compatible with UL60950.
Resin meets UL94 V0.
LCP02 is UL497B approved - file: E136224.
