Dionics-USA Incorporated, the inventor of the Photovoltaic (PV) optically-isolated MOSFET driver, is a major contributor to the advancement of the state-of-the-art in PV optically-isolated Solid State Relays.  In addition to expertise in micro-Photovoltaics (µPV), we pioneered the use of Dielectric Isolation processing for monolithic high-voltage IC's use in gas-discharge digitial displays.
