H11AV2FR2M

The H11AV2FR2M is a type of optoisolator, classified as a transistor, photovoltaic output. Optoisolators are devices used to transfer an electric signal from one circuit to another, usually as a means of signal isolation or protection.

H11AV2FR2M optoisolators contain two circuits – an input (the sending circuit) and an output (the receiving circuit) which are electrically isolated from each other. Light emitting diodes (LEDs) are used as the input component and a phototransistor is used as the output component. The LED is driven by the input current and emits light which is then sensed by a phototransistor, resulting in a current flow in the output circuit.

One of the factors to consider when selecting the H11AV2FR2M optoisolator is its maximum forward current rating. This is the maximum current that can be passed through the LED safely without damaging the optoisolator. The other main factor to consider is the forward voltage drop which, in the case of H11AV2FR2M, is approximately 4 volts.

H11AV2FR2M optoisolators find a wide variety of applications where signal transmission needs to be isolating. These devices are temperature stable and noise resistant so they can be used in applications such as digital signal transmission, data communication, process control, and switching applications. They can also be used to eliminate transient voltages and interface incompatible systems.

The working principle behind the H11AV2FR2M optoisolator is relatively simple. When an electrical current is applied to the input circuit, an LED within the device emits light that is then sensed by the phototransistor which in turn sets off a chain reaction in the output circuit. This stimulation by the phototransistor results in a current flow in the output circuit with the same characteristics as the input current, albeit in a different form. In this way, signals can be transferred from one circuit to another and foreign signals can be isolated from each other.

It can be seen that the H11AV2FR2M optoisolator is a useful device for transporting an electrical signal from one circuit to another, either for the purpose of noise immunity, transient protection, and/or incompatible system interfaces. This device features a low forward voltage drop and a high current rating, making it ideal for a variety of applications.
