Optoisolators - Transistor, Photovoltaic Output, H11AV2FR2VM Application Field and Working Principle

Optoisolators, or photocouplers, are devices designed to isolate electrical circuits by transferring signals optically. With no direct electrical contact between the input and output of the device, the optical connection not only provides electrical isolation, but also eliminates the possibility of electrical ground loop noise and electromagnetic interference (EMI). The H11AV2FR2VM optoisolator from Hirose is a transistor, photovoltaic output type, which offers the high-speed response needed for high speed logic signal isolation.

Application Field

The H11AV2FR2VM is designed as an isolator for digital signals. It can be used in general purpose digital isolation applications such as in the control and monitoring of industrial systems, as well as in consumer electronics applications such as audio systems. Its high speed switching capability also makes it suitable for use in communication systems, where high speed data transmission and isolation from interference is required.

Construction

The H11AV2FR2VM optoisolator consists of a light emitting diode (LED) and a phototransistor. The LED emits infrared light when a current is applied and is the input of the device. The phototransistor is positioned to detect the emitted light and is the output of the device. The output voltage level of the phototransistor is inversely proportional to the amount of light detected.

Working Principle

When an input is applied to the LED, it emits infrared light. This is detected by the phototransistor which activates and starts conducting, this in turn causes a change in the voltage level at the output. The output voltage will be inversely proportional to the amount of light detected by the phototransistor.This optical signal isolation allows for a variety of signals, such as logic signals, to be isolated with reliable transfer. The output voltage can be controlled by adjusting the input current, allowing for precise control and isolation of the signals.

Advantages

The primary benefit of using the H11AV2FR2VM optoisolator is the extremely fast transfer speed. With a switching speed of up to 1MHz, the device is capable of transferring logic signals with a high degree of reliability and accuracy. By using the LED and phototransistor, it also provides excellent isolation from electrical noise, making it ideal for applications in industrial and computer systems.The device is very compact and requires very little current to operate. This makes it ideal for use in high density circuitry, such as in communication systems, allowing it to be easily integrated into existing systems with minimal design or rework.

Conclusion

The H11AV2FR2VM optoisolator from Hirose offers a reliable, high speed solution for the isolation of logic signals. With its fast switching speed and excellent optical isolation, it is well suited for a variety of applications, such as control and monitoring of industrial systems, consumer electronics and communications systems. Its compact size and low power consumption make it an ideal solution for high density circuitry, making it easy to integrate into existing designs.
