The CT817 Series is a DC input 4-pin phototransistor optocoupler designed for high isolation applications. It features a gallium arsenide infrared-emitting diode optically coupled to a phototransistor within a 4-lead DIP package, with various lead forming options available. This series offers high isolation voltage up to 5000 VRMS and a wide operating temperature range from -55 C to 110 C. It is suitable for applications such as switch mode power supplies, computer peripheral interfaces, and microprocessor system interfaces.
