IXYS' Clare Subsidiary Expands AC-Power Switch Family by Offering 600V and 800V Devices for Improved Power Control and Efficienc

IXYS Corporation (NASDAQ: SYXI), announced today that
its wholly owned subsidiary, Clare, Inc., in Beverly, Massachusetts,
has expanded its family of AC-Power Switches with the introduction of
two new products, the CPC1962 and CPC1972. These products offer
designers peak blocking voltages of 600 volts and 800 volts
respectively. These devices use optical-coupling inputs, with dual
power Silicon Controlled Rectifier (SCR) outputs. In addition, tightly
controlled zero-cross circuitry ensures switching of 120 to 240 Volt
AC loads without the generation of transients.
   The CPC1962 has a continuous load current of 300mA while the
CPC1972 is rated for 250mA. The input and output circuits are
optically coupled to provide 3750Vrms of isolation and noise immunity
between control and load circuits. As a result the CPC1962 and CPC1972
devices are well suited for industrial environments where
electromagnetic interference could disrupt the operation of
electromechanical relays (EMRs), or where EMRs cannot be used due to
sparks.
   Both the CPC1962 and CPC1972 AC-Power Switches target replacing
EMRs in electrical systems, to control AC power to the loads, without
sparks, noise and at higher efficiency. These are fully Solid State
semiconductor switches that meet the requirements of a variety of
industrial applications including control circuits, switching panels
and gas pump electronics. Other switches on the market do not provide
this level of isolation, are more expensive and less reliable. These
devices are fully RoHS compliant and are available in 6-Pin DIP or
Surface Mount packages that offer significant size reduction in
typical applications.
   These devices are ideal for limiting the inrush current from the
AC line into switching power supplies, reducing the input circuit
power dissipation in off line power supplies in standby or in its
'off' mode. The devices are part of IXYS' energy efficiency power
semiconductor strategy to enable saving electrical power in power
systems.

   Clare, Inc., a leader in the design and manufacture of solid-state
relays and high voltage integrated circuits, is a wholly owned
subsidiary of IXYS Corporation. IXYS Corporation develops and markets
primarily high performance power semiconductor devices that are used
in controlling and converting electrical power efficiently in power
systems for the telecommunication and internet infrastructure, motor
drives, medical systems and transportation. IXYS also serves its
markets with a combination of digital and analog integrated circuits.
