KAQY412 Series
4PIN 60V N.C. TYPE SOLID STATE RELAY-
MOSFET OUTPUT
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.
