The MOCD207R2M with Transistor Output Optocouplers 8-Pin Optocoupler 2Ch Phototransistor, manufactured by ON Semiconductor, is an 8-pin optocoupler consisting of a photosensitive element integrated with a driver transistor. It has two independent channels, each with a photosensitive element and a driver transistor. It provides a high degree of electrical isolation between input and output circuits. It has a high common-mode transient immunity of up to five kV/µs and the ability to switch both AC and DC. Its compact size and low power consumption make it an ideal choice for applications with space and power requirements.
