Optoisolators - Transistor, Photovoltaic Output, also known as H11G1300 isolators, are devices designed to transfer electrical signals between two or more circuits while isolating the circuits from one another, thereby providing protection and electrical isolation between circuits. They consist of two parts, a light detector and a light emitting diode (LED). The LED emits light when an electrical current passes through it. The light is then detected inside the detector, which then causes an electric output in the form of a transistor.

The H11G1300 optoisolator has an operating temperature range of -40 to 125°C and high voltage isolation range of >2500Vrms, making it suitable for a range of high temperature and high voltage applications. It is common to find applications of H11G1300 optoisolators in industrial controls, automotive electronics, medical electronics, and household appliance circuits.

In terms of functionality, H11G1300 isolators function as switches. This is done by a mechanism which consists of a light producing diode and a photodetector. In the circuit, the LED is forward biased and current is passed through it when a signal is sent. The light produced is then detected by the photodetector. This causes a voltage change which is ultimately passed through the transistor to provide the required output.

One of the most important advantages of H11G1300 optoisolators is reduced noise caused by electrical interference between circuits. Additionally, they provide high voltage isolation and thus prevent electric shock to the user. Moreover, they are less prone to electrical power surges and can operate at a wide range of temperatures thus giving them a very long life span.

The optoisolator can also be used for interlocking circuits. Here, two circuits can be kept isolated from one another but when one circuit is activated it opens the connection to the other, allowing electrical communication. This type of interlock is highly efficient and prevents short circuits and damage from incorrect voltage levels.

Overall, H11G1300 optoisolators provide a safe and reliable way to transfer a signal between two circuits while providing electrical isolation. They can be used in a wide range of applications due to their wide temperature and voltage range and their low susceptibility to electrical noise. Furthermore, they are used extensively for interlocking circuits thus providing higher safety for the user.
