Optoisolators are electronic components that use light as an isolating medium, meaning that they can transfer signals electrically by converting them into light which is transmit across a physical layer, such as an air gap or a piece of plastic. One of the most common forms of optoisolator is the H11B815W Transistor, Photovoltaic Output. It accomplishes this task by using an infrared LED, which is connected to a phototransistor, allowing it to function as a signal amplifier.

The H11B815W is a specialized form of optoisolator, specifically designed for the task of transferring signals between two points without making any physical contact. This makes it ideal for situations where an electrical connection is not feasible, such as in high voltage or high current applications, or in applications where the two points are isolated from each other. H11B815Ws can be used on circuit boards in both 5V and 12V configurations. In 5V mode, the current draw is only 3mA, making it ideal for low-power applications. In 12V mode, the current draw is increased to 9mA, allowing for stronger, more reliable signals.

The H11B815W works by converting electrical signals into light, which is then transmitted across a physical gap. The two sides of the gap are connected to an LED and a phototransistor respectively. When an electrical signal is applied to the LED, it sends out an intense beam of infrared light. This beam passes through the physical gap and is intercepted by the phototransistor, which converts the light into an electrical signal and amplifies it. The amplified electrical signal is then sent back to its original source.

The phototransistor is designed to specifically detect infrared light, making it well-suited for use with the LED. The phototransistor is also able to amplify the signal, allowing for a longer signal range and better performance. The H11B815W also features a dielectric insulation layer, which acts as a barrier between the two sides of the gap and prevents any electrical interference. This helps ensure that the signal is not affected by external noise sources, such as electric motors or fluorescent lights.

The H11B815W is a versatile and reliable optoisolator, suitable for a variety of applications. It can be used as a signal amplifier in audio and video systems, as well as for automotive applications and other industrial applications. Its ability to transfer signals across a physical gap without making contact makes it particularly useful in highly sensitive areas, such as medical equipment. It is also often used as an output device for electrical surge protection systems.

The H11B815W is a reliable and versatile optoisolator, designed to transfer signals between two points without making physical contact. Its infrared LED and phototransistor system amplifies and transmits the signal, allowing for a longer signal range and improved performance. Additionally, its dielectric insulation layer helps to block out any external interference. The H11B815W is suitable for a variety of applications, including medical equipment, automotive applications, and audio and video systems, as well as for electrical surge protection.
