KAQW412 Series
cosmo
Description
The KAQW412 series contains two normally close
switches that can be used as two independent SPST
relays or as one DPST relay. The relays 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.
