Optoisolators are functionally equivalent electrical isolation systems, which involve the use of a photosensitive device, typically a low current LED and a phototransistor. The H11AG1300 optoisolators (transistor, photovoltaic output) offer industry-leading performance and are designed for harsh environment applications. They provide optical isolation between two or more circuits or devices within the same system, preventing signals and digital state to cross over and affecting the performance of each component.

The optoisolator variant of the H11AG1300 is a highly reliable transistor optoisolator. It is a surface mount device consisting of a GaA/As infrared emitting diode (LED) input, and a phototransistor output. The LED is used to optically isolate the two circuit components. The isolated circuit, on the other hand, will be connected to an external phototransistor, whose collector current will detect the voltage and current from the input. A built-in suppression diode is responsible for suppressing the potentially harmful voltages present in the system.

The H11AG1300 optoisolator works by using a phototransistor to act as a transducer, converting light energy into electrical signals. The transistor amplification of the phototransistor produces an amplified output signal that is proportional to the input light energy. The phototransistor will be configured to regulate the voltage output of the device to suit the intended application.

The optoisolators principle of operation relies upon the fact that the LED emits a beam of light when an input is applied to it. The light is coupled to the phototransistor which detects it, thus producing an amplified output signal. The H11AG1300 optoisolator is designed to work over a wide range of temperatures, ranging from -55 to +125°C, and is compliant with a wide range of industrial applications. This makes it an ideal solution for data line protection and signal transmission in harsh and extreme conditions.

The H11AG1300 optoisolator is widely used in the automotive, industrial control, medical, military, and aerospace industries. These optoisolators offer long-term reliability and are cost-effective, making them a preferred choice for many applications. In automotive applications, they are used for digital data line protection, such as data bus and power line protection, in anti-lock braking systems and ABS stability control systems. In the medical industry, the optoisolator can be used in EEG, EMG and ultrasound imaging. They are also used in military, aerospace and industrial control systems for the protection of RF signal and power lines.

The H11AG1300 optoisolator is widely used in various industries and for a wide range of applications. It offers higher efficiency, long-term reliability, and cost-effective solutions for signal transmission and data line protection. The device is designed to work over a wide temperature range, making it ideal for harsh and extreme environments. The H11AG1300 optoisolator is therefore the go-to choice for many engineers looking for reliable performance over long periods of time.
