CNY Series High Isolation Voltage Optocouplers

Vishay Semiconductors CNY Series High Isolation Voltage Optocouplers are category IV high voltage isolation optocouplers available in a surface mount package. The high isolation voltage SMD version optocouplers consist of a phototransistor optically coupled to a gallium arsenide infrared-emitting diode in a 4 pin plastic package. The single components are mounted opposite one another, providing a distance between input and output for high safety requirements of >3mm. Vishay Semiconductors CNY Series High Isolation Voltage Optocouplers are ideal for such applications as solar equipment, smart meters, and smart grids.
