Silicon Avalanche Diodes
1500 Watt Axial Leaded Transient Voltage Suppressors
LCE Series
Device for data line interface circuit protection, the LCE series
offers low shunt capacitance to prevent signal degradation.
These devices can be used across transmission lines with signal
levels up to 100MHz. For bi-directional applications, two LCE
suppressors are required, connected anti-parallel with respect to
each other, across the circuit to be protected.
