Optoisolators, also known as optocouplers, are used for signal transmission between two isolated circuits. They provide electrical isolation between the input and output, preventing direct current from passing from one circuit to the other. A wide range of optoisolator devices are available in the market today, with various features and capabilities. CNY17-1-000E is one such type of optoisolator.

CNY17-1-000E is a transistor-output type optoisolator with a photovoltaic output. It is designed with a GaAIAs infrared-emitting diode (IRED) and a NPN silicon photosensitive transistor, which can switch electrical loads at a specified current level. It is used for a variety of signal transmission or switching applications, such as in automotive, industrial and lighting applications.

The CNY17-1-000E optoisolator has a monolithic structure with an integrated self-contained optoelectronic component including an emitter and a detector. The optoelectronic component is packaged inside a 4-pin dual in-line plastic package (DIP). The package has two pins on each side, with an internal 5mm minimum clearance. The emitter features a high optical power of up to 200 milliwatts from a distance of 10 meters, and the detector features a high responsivity and low capacitance of up to 1 picofarad.

The working principle of such optoisolators is based on the ability of a photovoltaic effect to create an electric potential by the transmission of light energy into electrical energy. When an incident light beam is focused on the photosensitive transistor, the photons interact with the base-collector junction, generating an electron-hole pair. This is known as photocurrent. This photocurrent creates a voltage potential across the collector-emitter terminals, which in turn can switch an electrical load.

The device is characterized by a low input current of up to 4mA when operated at a voltage as low as 4.5 volts, low dark current of up to 10 microampere, and low junction capacitance of up to 100 picofarad. It is also equipped with an internal safety output switch, which prevents any unauthorized access or voltage fluctuations. The device has a response time of 16 microseconds and can withstand up to 200 kilovolts of electrostatic discharge (ESD). With these features, this optoisolator is suitable for high volume, low cost, and secure switching applications.

The CNY17-1-000E optoisolator is used in a number of applications including AC line protection, optical fire alarm systems, controlled lighting systems, automotive ignitions, AC motors, and industrial machinery controls. It is also used for short duration power switching such as motor control, or dimming applications. It is an ideal solution for applications that require speed, precision, and secure signal transmission.
