Optoisolators are electrical components that use optical (light) signals to transfer electrical signals between circuits without allowing them to electrically mix. The main purpose of optoisolators is to isolate two circuits while maintaining a signal communication between them. The H11AV2SM optoisolator is a great example, as it provides a strong isolation barrier with the electrical characteristics of a transistor photovoltaic output.

The H11AV2SM optoisolator is a multi-channel device, providing reliable isolation between circuits. It has a high breakdown voltage of up to 8,000 Vrms. It also has high isolation resistance of 10¹²Ω, ensuring a reliable isolation barrier between circuits. The device is UL and CSA certified, ensuring convenient conformity to the safety regulations of most countries. The optoisolator has an integrated dual-channel photo transistor output stage for driving up to 800 mA current. It also features an overvoltage protection circuit, ensuring a safe operation even in emergency situations.

The H11AV2SM optoisolator is most commonly used in safety-critical applications, such as switchgear, circuit breakers, variable speed drives, and other industrial and medical equipment. It is also used in wearable electronic devices and home automation systems. The device\'s reliability makes it ideal for use in these applications.

The working principle of the H11AV2SM optoisolator is based on the principle of light transmission through an optically transparent medium. The optoisolator consists of an LED circuit on one side and a photo transistor circuit on the other. The LED circuit is connected to the input signal, which emits light when the signal is activated. The light then passes through an optical channel in the device, and is received by the photo transistor. The photo transistor then converts the light into an electrical signal, which is then sent to the output. The output signal is isolated from the input signal by the optoisolator’s high insulation resistance.

The H11AV2SM optoisolator is an excellent choice for electrical applications that need reliable signal isolation between circuits. It is a robust, UL and CSA certified device, ideal for safety-critical applications. The optoisolator’s high isolation resistance and integrated dual-channel photo transistor output stage ensures reliable and safe operation.
