Optoisolators are electrical devices used to provide isolation between two electrical circuits. A typical optoisolator consists of a light emitting diode (LED) or an infrared energy emitting diode (IRED) connected to a photosensitive detector such as a photodiode or a phototransistor. The EL817 optoisolator is a type of transistor, photovoltaic output optoisolator that uses a phototransistor as the output detector.

EL817 optoisolator has a wide range of applications as it is capable of handling up to 200 mA of peak current. It is primarily used for power switches, signal switches, input/output transducers, optocouplers, voltage regulators, and other control circuits. The optoisolator is capable of providing up to a 5 kV isolation with very low leakage current. It is widely used in telecommunications, computer peripherals, office automation equipment, security systems, industrial control systems, and automotive applications.

The working principle of the EL817 optoisolator is simple and straightforward. A light signal from the LED side is directed to the phototransistor side. When the light signal hits the phototransistor, electrons are excited and move into the transistor’s base. This causes a current to flow in the collector-emitter circuit and turns on the output phototransistor. The output phototransistor then provides a signal to the load.

The EL817 optoisolator offers several advantages over traditional isolators. It is faster than traditional optoisolators, can operate over wider temperature ranges, and is immune to electrical interference. Additionally, it offers superior reliability due to the hermetically sealed construction. It is also immune to vibration, shock, and most forms of electrical and electro-magnetic radiation. Furthermore, it is capable of providing high output current and voltage.

Overall, the EL817 optoisolator is a versatile and reliable device ideally suited for use in a variety of applications. Its ability to provide isolation between two circuits as well as provide high levels of current and voltage make it an ideal choice for use in industrial, automotive, and telecommunications applications. Additionally, its fast response time, immunity to electrical interference, and hermetic sealing make it a reliable and cost-effective solution.
