Clare, Inc., an IXYS company (NASDAQ: SYXI – News), today announced that it has expanded its family of AC-Power Switches with the CPC1962 and CPC1972, offering designers peak blocking voltages of 600 and 800 respectively. The 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 240Volt 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 which 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 systems.
