IXYS Introduces 20A Voltage-Controlled Optically Isolated AC Power Switch

Utilizing Dual-Power SCR Outputs

The CPC44055ST is an 800V Voltage-Controlled Device in Unique SuperSIP Package

 

Beverly, MA – September 15, 2015. IXYS Integrated Circuits Division (ICD), Inc., a wholly owned subsidiary of IXYS Corporation (NASDAQ:IXYS), announced the availability of the CPC44055ST 20A(rms), (5A free-air), AC Power Switch.  The voltage-controlled CPC44055ST which features zero-cross turn-on circuitry, is specified with an 800V peak blocking voltage and is the latest addition to the SuperSIP family. Previously, IXYS ICD released the CPC40055ST AC Power Switch which is a current-controlled device with similar specifications. Tightly controlled zero-cross circuitry ensures low noise switching of AC loads by minimizing the generation of transients.

 

The CPC44055ST’s optically coupled input and output circuits provide exceptional noise immunity and 2500V(rms) of isolation between the control input and the output. As a result, the CPC44055ST is well suited for industrial environments where electromagnetic interference would disrupt the operation of plant facility communications and control systems.

 

The unique SuperSIP package pioneered by IXYS ICD enables Solid State Relays to achieve the highest load current available in any similarly sized package and is pin-to-pin compatible with the industry standard AC Output Module. This package features a unique process in which the silicon chips are soft-soldered onto a ceramic Direct Copper Bond (DCB) substrate instead of the traditional copper lead frame. The DCB ceramic, the same substrate used in high power modules, provides not only 2500V(rms) of input-to-output isolation but also very low thermal impedance (0.35 C/W).

 

This device can be used with a heatsink to achieve 20A(rms) output current or without a heatsink to achieve 5A(rms).  The CPC44055ST requires only 5V of input control voltage to operate. Additionally, the SuperSIP package meets UL508 (Industrial Controls) pin-to-pin distance requirements.

 

Typical applications include AC motors up to 1/2 HP, AC line power control, high intensity lighting, UPS, Appliances and factory automation.
