KAQW212 Series

8PIN 60V N.O. TYPE

SOLID STATE RELAY-MOSFET OUTPUT

 Description

The KAQW212 series contains two normally open

switches that can be used as two independent SPST

relays or as one DPST relay. The relay is constructed

using a GaAlAs LED for actuation control and an

integrated monolithic dies 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.
