KAQY412 Series
cosmo
Description
The KAQY412 series is robust, ideal for telecom and
ground fault applications. It is a SPST normally close
switch (1 Form B) that replaces electromechanical relays
in many applications. It is 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 circuitry and MOSFET
switches.
