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).
