Optoisolators - Transistor, Photovoltaic Output

Optoisolators offer a number of technological advantages to electrical engineers, enabling them to transfer electrical signals from one circuit to another without allowing the circuits to interfere with each other. They are especially useful when working with high-voltage circuits, as they allow signals to be sent over significant distances without creating a safety hazard. One of the most popular optoisolator components is the EL3H7(E)-G, which has many applications and utilizes an interesting design and working principle to function effectively.

EL3H7(E)-G Overview

The EL3H7(E)-G is a six-lead optoisolator manufactured by Sanyo Semiconductor. It has a bipolar NPN transistor photovoltaic output, which means it requires a voltage supply to work. The component is resistant to noise, has a wide range of operating voltage, and comes with a high isolation voltage of 5KV MM. It also offers a transistor output, with a power dissipation rating of 400 mW and a collector-emitter voltage of 80v. Overall, the EL3H7(E)-G is very reliable and durable, making it ideal for use in electrical circuits where reliability and durability are required.

Applications of EL3H7(E)-G

Due to its robust design and impressive features, the EL3H7(E)-G has a wide range of applications. It is commonly used for the isolation of low-level analog signals, such as thermocouples or resistance-measuring circuits. Additionally, due to its noise-resistance characteristics, it is often used in communication systems or any other circuits where interference can cause instability. Furthermore, due to its high isolation voltage, it is widely used to protect delicate circuits from power shock or any other electrical overloads.

Working Principle of EL3H7(E)-G

The EL3H7(E)-G optoisolator operates on an interesting principle. It works by forming a voltage-driven, photo-electric junction between its circuit and the external circuit. It utilizes the voltage supply to create an electric field, which is then used to control an LED light source. This LED light source is then used to convert the electric signal from the external circuit into an optical signal, which is then sent to the EL3H7(E)-G circuit. The circuit then captures this optical signal with a photodiode, which converts it back into an electric signal. The electrical signal is then amplified by the photovoltaic output transistor, which sends it to the rest of the external circuit. This enables it to transfer the signal without having the external circuit interfere with the internal circuit of the component. Overall, the EL3H7(E)-G is an impressive optoisolator component that can be used in a wide range of applications. Its noise-resistant design, wide operating voltage, and high isolation voltage make it ideal for use in many different scenarios. Its working principle of forming a voltage-driven, photo-electric junction also allows for reliable signal transfer over considerable distances. For these reasons, the EL3H7(E)-G is one of the most popular optoisolator components on the market.
