Optoisolators are devices designed to provide electrical isolation between two circuits. An optoisolator, also known as an optocoupler, opto-isolator, photocoupler, or photoMOS, is a device that transfers electrical signals between two isolated circuits by using light. H11B2S (TB) optoisolator is a type of optoisolator that utilizes a transistor, photovoltaic output.

The H11B2S (TB) optoisolator contains a phototransistor optically coupled to a gallium arsenide infrared-emitting diode in a 6-pin dual inline package. The device is designed to provide high current gain, allowing the phototransistor to be switched with a relatively low input power. It can also be used to amplify low-level analog signals. The H11B2S (TB) optoisolator features a wide range of operating voltage and temperature ranges, making it suitable for use in a variety of applications.

The working principle of the H11B2S (TB) optoisolator is straightforward. A gallium arsenide infrared-emitting diode is used to turn on the phototransistor via a photocurrent created by illuminating the diode with light. The phototransistor then switches on and off in response to the intensity of the light. When the light intensity increases, the current flowing through the phototransistor increases and the transistor turns on. When the light intensity decreases, the current flowing through the phototransistor decreases and the transistor turns off.

The H11B2S (TB) optoisolator has many applications. It can be used to control current in relays, motors, solenoids, lamps, switches, and other devices. It can also be used in analog circuits as an amplifier, as a voltage regulator, or as a voltage-level detector. It can be used to sense the position of a motor shaft, or to detect the speed of rotating machinery.

The H11B2S (TB) optoisolator is an ideal option for applications that require electrical isolation, high current gain, and low input power. Highly reliable and cost-effective, the optoisolator can be used in a wide range of applications, from medical equipment and consumer electronics to industrial automation and robotics.
