Profile: Dionics, Inc. offers photovoltaic optically-isolated mosfet driver. Our ISO-gate microcircuits are optically coupled floating power sources used primarily to control power MOSFETS when electrical isolation between input and output is required. We provide a full line of stock optoelectronic & photovoltaic components, integrated circuits and semiconductor devices. Our photovoltaic solid state relays feature optical isolation, low logic-level input, compatibility, low on-resistance, low offset voltage, low off-state leakage current, current limiting and thermal protection with hysteresis. It is used in applications such as motor control, aircraft flight control systems, medical electronics, automatic test equipment and data acquisition.
