Clare - Optically Isolated SCR AC-Power Relay with Zero-Cross Circuitry in i4-PAC Package

Optically coupled circuitry provides exceptional noise immunity and 2500Vrms of isolation between the low voltage control and the high voltage output. Additionally, the 150Amp surge rating enables the CPC1998 to handle a variety of resistive and reactive loads. As a result, the robust CPC1998 is well suited for industrial environments where electromagnetic interference would disrupt facility operations.

The CPC1998 comes in the unique i4-PAC package, pioneered by IXYS, which allows Clare’s Solid State Relays to achieve the highest load current and power ratings. This package features a unique IXYS process in which the silicon chips are soft soldered onto the Direct Copper Bond (DCB) ceramic substrate instead of the traditional copper leadframe.

The DCB ceramic substrate, the same as used in high power modules, not only provides 2500Vrms isolation, but also very low thermal resistance (0.35°C/W).

Minimum input control current to the input infrared LED for switching is 5mA. Applications include: Power management, motor control, heat coil control, valve and solenoid control, robotics, IT and server power supplies, medical equipment, railroad and traffic controls, consumer electronics, industrial controls, and, test and measurement equipment. The CPC1998, available in the i4-PAC package, is a UL 508 Recognized component for industrial control equipment.

“This product from Clare expands the family of power Solid State Relays (SSRs) that can be used with the Zilog (also an IXYS company) family of MCUs for power management application and to control power to loads. It is of special importance for energy saving applications to reduce the power consumption in systems by turning off the power to loads as needed,” commented Dr. Nathan Zommer, CEO of IXYS Corporation.
