Silicon Avalanche Diodes 1500 Watt Axial Leaded Transient Voltage Suppressors LCE Series (R) 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.
