Optoisolators, also known as optical couplers, consist of a light-emitting element coupled with a light-sensitive element in a single package. The H11B3-V optoisolator is an example of this type of device. It contains a phototransistor-LED pair, which are driven and interconnected in such a way as to provide galvanic isolation between the two circuits. The H11B3-V is designed for operation in the visible light spectrum, typically in the red-green wavelength range.

The H11B3-V is typically used in systems to isolate two circuits electrically while permitting information to pass between them through light. The internal circuitry consists of a phototransistor which faces an LED on the other side of the package. When the LED is forward biased by the input circuit, photons are emitted, some of which may strike the phototransistor and cause it to conduct. The current flowing in the phototransistor generates an open-collector output to the output circuit.

The H11B3-V has a variety of applications in different systems. It can be used as an interface between digital logic circuits and analog signals, as well as between two logic or power levels in order to provide electrical isolation between them. It can also be used to transmit and isolate signals from noise or high voltage sources, and is often used in process control, telecommunications, and industrial automation systems. The device is also useful in medical applications such as portable ECG monitors and pacemakers, where electrical isolation between patient and equipment is essential.

The H11B3-V optoisolator is a reliable and versatile device for isolating two circuits. It functions by relying on the principles of quantum mechanics, where photons are emitted at a rate determined by the electrical input current. Photons in turn cause a current to flow in the phototransistor, providing an open-collector output. This type of optoisolator is well suited to many different applications due to its inherent reliability, low cost, and flexibility.
