LCP02-150B1
The series resistors Rs1 and Rs2 designed in
PTCs which are needed to withstand the power contact or the power induction tests
imposed by the country standards. Taking this factor into account, the actual lightning surge
current flowing through the LCP02-150B1 is equal to :
With
For a line card with 50 Ω of series resistors which has to be qualified under Bellcore 1000 V
10/1000 µs surge, the present current through the LCP02-150B1 is equal to :
The LCP02-150B1 topology is particularly optimized for the new telecom applications such
as fiber in the loop, WLL systems, decentralized central office for example.

battery voltages. With such a protection the SLIC is protected against surge over +Vb and
lower than -Vbat. In this case, +Vb can be programmed up to +120 V while -Vbat can be
programmed down to -120 V.
I surge = Vsurge / (Rg + Rs)
V surge = peak surge voltage imposed by the standard.
Rg = series resistor of the surge generator
Rs = series resistor of the line card (e.g. PTC)
I surge = 1000 / (10 + 50) = 17 A
