Description
The LH1520 dual 1 Form A relays are SPST normally
open switches that can replace electromechanical
relays in many applications. They are constructed
using a GaAIAs LED for actuation control and an inte-
grated monolithic die for the switch output. The die,
fabricated in a high-voltage dielectrically isolated
technology is comprised of a photodiode array, switch
control circuitry, and MOSFET switches. In addition,
the LH1520 SSRs employ current-limiting circuitry,
enabling them to pass FCC 68.302 and other regula-
tory surge requirements when overvoltage protection
is provided.
