The LH1505 contains two normally open switches that can be used as two independent SPST relays or as one DPST relay. The relay is constructed using a GaAlAs LED for actuation control and integrated monolithic dies for the switch outputs. The die, fabricated in a high-voltage dielectrically isolated technology, is comprised of a photodiode array, switch control circuity, and DMOS switches. In addition, the LH1505 relay employs currentlimiting circuity, enabling it to pass FCC 68.302 and other regulatory voltage surge requirements when overvoltage protection is provided.
