Optoisolators are components that use a light-sensitive device (sensor) to electrically isolate another device from a circuit. They’re commonly used in advanced electronic and medical equipment that requires protection from external factors such as noise, reverse voltages, and inductive electrical pulses. The EL817(S1)(B)(TD)-VG is an optoisolator that uses a transistor-photovoltaic-output (TPO) system to provide superior isolation and protection. In this article, we’ll discuss the application fields of the EL817(S1)(B)(TD)-VG and the operating principle of its TPO system.

Application Fields: The EL817(S1)(B)(TD)-VG is often used in systems that require a high level of isolation between individual components. Typical applications include noise suppression, RV and ESD protection, signal circuit driving, medical equipment, serial and parallel communication and control circuits, and automation and control systems. The EL817(S1)(B)(TD)-VG is also popular for isolating and driving LEDs and other light sources, and for medical applications that require a high level of electrical isolation.

Working Principle: The EL817(S1)(B)(TD)-VG optoisolator utilizes a transistor-photovoltaic-output (TPO) system that provides superior isolation and protection. It consists of an input LED, an output transistor, and a photovoltaic photosensitive element, all of which are electrically isolated. When the input LED is illuminated by anode current, a photovoltaic potential is created that activates the output transistor. This triggers a corresponding action in the output circuit, allowing the EL817(S1)(B)(TD)-VG to control current and voltage in the output circuit. The EL817(S1)(B)(TD)-VG can provide up to 15kV/μs of common mode rejection, making it ideal for isolating and driving LEDs, other light sources, and medical applications that require electrical isolation.

The EL817(S1)(B)(TD)-VG optoisolator is a highly reliable device that can provide excellent electrical isolation for a wide range of applications. It utilizes a transistor-photovoltaic-output (TPO) system that provides superior isolation and protection, making it ideal for use in noise suppression, RV and ESD protection, signal circuit driving, medical equipment, serial and parallel communication and control circuits, and automation and control systems. With its high level of electrical isolation and common mode rejection, the EL817(S1)(B)(TD)-VG is a great choice for isolating and driving LEDs and other light sources, and for medical applications.
