Optoisolators are electrical devices designed to safely feed signals between two circuits that operate at different voltage levels. The OPIA814ATUA is a type of optoisolator, more specifically a transistor, photovoltaic output optoisolator, which is ideal for providing electrical isolation between two circuits. This device offers a high speed response, strong noise immunity, and high current output while providing bidirectional signal communication.

The OPIA814ATUA’s key features include isolation between primary and secondary circuits of up to 4000 VRMS, a 0.5 Mbps signal speed, power dissipation of 4.0 mW, a CTR of 40% to 125%, and a stand-off voltage of 6.5 to 16.0V DC. The device’s maximum voltage rating is 80V, and its maximum operating temperature is +85 degrees Celsius.

The working principle of the OPIA814ATUA, as with many optoisolators, is based on a phototransistor. This phototransistor uses an LED as the light source and is triggered when current passes through the LED. When the LED is activated, it creates an incident light which is absorbed by the phototransistor, creating a current flow through the transistor’s collector and emitter. This current flow is then used to control the voltage output of the optoisolator.

The OPIA814ATUA is mainly used in isolation applications where two circuits need to communicate with each other but must remain electrically isolated. This device is also used in safety-critical signage, AC/DC motor control, and signal communications. The device is also designed to meet automotive safety standards, so it is often used in automotive applications. Its strong noise immunity makes it ideal for use in industrial or automation applications.

The OPIA814ATUA transistor, photovoltaic output optoisolator offers a wide range of features and can be used in a variety of applications. It is designed to provide electrical isolation between two circuits, with a high speed response, strong noise immunity, and high current output. The device meets automotive safety standards and is often used in isolation applications, safety-critical signage, AC/DC motor control, signal communications, and industrial or automation applications.
