The output is constructed with efficient MOSFET switches and photovoltaic die that use Clare’s patented OptoMOS architecture while the input, a highly efficient GaAlAs infrared LED provides the optically coupled control. The combination of low on-resistance and high load current handling capability makes this relay suitable for a variety of high performance switching applications. The unique ISOPLUS-264 package pioneered by IXYS allows Solid State Relays to achieve the highest load current and power ratings. This package features a unique IXYS process where the silicon chips are soft soldered onto the Direct Copper Bond (DCB) substrate instead of the traditional copper leadframe. The DCB ceramic, the same substrate used in high power modules, not only provides 2500Vrms isolation but also very low thermal resistance (0.3 °C/W).
