SL1011A/B and SL1411A Series

2 Electrode GDT Graphical Symbol

The SL1011A/B and SL1411A series provides high

levels of protection against fast rising transients

in the 100V/µs to 1kV/µs range usually caused by

lightning disturbances.

The SL1011A/B and SL1411A series offers low

capacitance (< 1.5pf) which provides low insertion

loss at high frequencies.

SL1011A offers 5kA protection without destruction

whereas the SL1011B and SL1411A offer 10kA surge

protection without destruction (maximum single

surge of 12kA @ 8/20µs).
