cosmo 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.
