DESCRIPTION
The LH1503 relays are DPST normally open switches
(2 Form A) that can replace electromechanical relays in
many applications. The relays are constructed using a
GaAlAs LED for actuation control and an integrated
monolithic die for the switch output. The die, fabricated
in a high-voltage dielectrically isolated technology, is
comprised of a photodiode array, switch control circuity,
and DMOS switches. In addition, these relays employ
current-limiting circuity, enabling them to pass FCC
68.302 and other regulatory voltage surge requirements
when overvoltage protection is provided.
