EL3H7(A)(TB)-VG Optoisolators - Transistor, Photovoltaic Output Application Field and Working Principle

Optoisolators are devices used to transmit electrical signals between two isolated circuits, providing electrical insulation and preventing the transfer of electrical noise, voltage transients and other electrical interference. The EL3H7(A)(TB)-VG from Vishay Semiconductor is a type of optoisolator specifically designed for switching and logic gate applications. In this article, we will discuss the application field of the EL3H7(A)(TB)-VG and how it works.The EL3H7(A)(TB)-VG is designed for high voltage and high speed switching, logic gate applications, and general photovoltaic isolators. This optoisolator offers a variety of features that provide an exceptional level of electrical isolation and power performance. Its actual switching voltage is 5.7V (min) and 8V (max), while the switching speed is 4.3 µs (min). It also offers excellent protection against externally induced high voltages, and its optical output is capable of driving TTL and CMOS logic circuits.The working principle of the EL3H7(A)(TB)-VG is based on the process of optical isolation. This process works by using an infrared LED as the input and a photovoltaic cell as the output. When current flows through the LED, light is emitted which is then collected by the photovoltaic cell. The light energy is then converted into electrical current, which is transmitted to the output device.Because of its exceptional electrical isolation characteristics, the EL3H7(A)(TB)-VG is widely used in industrial, consumer electronics, medical, automotive, and military applications. It is used for logic level-shifting, isolating power sources, and as a security device. It is also used in telecommunications, providing a high degree of isolation between the transmitting and receiving signal.The EL3H7(A)(TB)-VG is also capable of providing protection against transients and surges. Its design includes a unique three-stage isolation barrier that effectively isolates potential electrical spikes and prevents them from affecting input or output devices. This allows it to be used in applications that require extreme levels of protection, such as medical electronic devices and military systems.In summary, the EL3H7(A)(TB)-VG is a high performance optoisolator capable of providing exceptional levels of isolation and power performance. Its wide range of features and design make it suitable for a range of applications, including logic level-shifting, isolating power sources, and providing protection against transients and surges. Its fast switching speed and high voltage characteristics make it an ideal solution for industrial, consumer electronics, medical, automotive, and military applications.
