KAQY212 Series

4PIN 60V N.O TYPE

SOLID STATE RELAY-MOSFET OUTPUT

􀁺 Description

The KAQY212 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, fabricated in a high-voltage

dielectrically isolated technology, is comprised of a

photodiode array, switch control circuitry and MOSFET

switches.
