As part of that family, the is a 1-Form-A solid state relay. The employs optically coupled MOSFET technology to provide V rms of input to output isolation. The efficient MOSFET switches and photovoltaic die use Clare s patented OptoMOS architecture while the input is controlled by a highly efficient GaAlAs infrared LED. The combination of low on resistance and high load current handling capabilities makes the relay suitable for a variety of high performance switching applications. The unique i4-pac package pioneered by IXYS allows solid state relays to achieve the highest current and power ratings. This package features an IXYS unique process where the silicon chips are soft soldered onto the Direct Copper bond (DCB) substrate instead of the usual copper leadframe. The DCB ceramic, the same substrate used in high power modules, not only provides V rms isolation, but also very low thermal resistance.
