KAQY210 Series

4PIN 350V N.O TYPE

SOLID STATE RELAY-MOSFET OUTPUT

 Description

The KAQY210 series is robust, ideal for telecom and

ground fault applications. It is a SPST normally open

switch (1 Form A) 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 is fabricated in a

high-voltage dielectrically isolated technology and is

comprised of a photodiode array, switch control circuitry

and MOSFET switches.
