IXYS Integrated Circuits Division Introduces High Current Optically Isolated AC Power Relay with Zero-Cross Circuitry and Highest Isolation Voltage Rating

The CPC1966B AC Power Switch is ideal for saving energy in power systems for Industrial, IT, Consumer and Medical Products

Beverly, Massachusetts, USA – IXYS Integrated Circuits Division (“ICD” formerly Clare, Inc.), a wholly owned subsidiary of IXYS Corporation (NASDAQ: IXYS), announced the immediate availability of the CPC1966B, 3A (rms) AC Power Relay.  The CPC1966B is an AC Solid State Switch utilizing dual power SCRs as an integrated alternative to discrete optocoupler and triac circuits. This device includes zero-cross turn-on circuitry to minimize the generation of transients, and has a blocking voltage of 800V.

The new 8-Pin Power SOIC package provides 5000V (rms) of isolation between the input control and the output while optically coupled circuitry provides exceptional noise immunity.  Additionally, the 30Amp surge rating enables the CPC1966B to handle a variety of resistive and reactive loads.   As a result, the robust CPC1966B is well suited for industrial environments where electromagnetic interference would disrupt the operation of plant facility communications and control systems.

Input control current to the infrared LED for switching is 5mA.  Applications include: Motor controls, AC power control, valve and solenoid controls, security door and gate latches, lighting, AC power generation and distribution, home automation and HVAC controls.

“This product expands the power range of our SSR’s, and with our Zilog MCU’s, provides a total system solution for digital power and load management, that is desirable for our customers to save energy and automate their equipment. Thus it’s ideal for robotics, IT and server power supplies, medical equipment, railroad and traffic controls, consumer electronics, fitness equipment, industrial controls, and, test and measurement equipment”, commented Dr. Nathan Zommer CEO of IXYS.

The CPC1966B, available in the 8-pin Power SOIC package, is pending certification to the UL 508 Standard for industrial control equipment.

Pricing and Availability

The CPC1966B AC Power Relays are available in production quantities.  Pricing for OEM quantities of 25KU is $1.70.
