Optoisolators - Transistor, Photovoltaic Output

Optoisolators, also known as opto-couplers and photocouplers, provide electrical isolation between two circuits with the aid of a combination of an infrared emitting diode and a light sensing transistor. The H11B2M-V optoisolator is a 3-pin, 4-pin, or 5-pin photovoltaic output transistor device, many of which come in a small, industry standard, 5-pin dual in-line package (DIP). This optoisolator is designed for applications that require electrical isolation between two circuits, such as microprocessor to power conversion applications.

The H11B2M-V optoisolator has a built-in infrared LED and phototransistor, which are separated and interactive with a plastic channel in order to provide electrical insulation between two terminals, allowing the output voltage to be better controlled and stabilized. According to the Faraday\'s Law of Electromagnetic Induction, a voltage is induced in a coil of wire when the magnetic flux through the coil changes. In the case of the H11B2M-V optoisolator, this law states that if a magnetic field or an electric current changes, a voltage will be activated across the LED. This activates the LED, which then applies a current to the transistor\'s base, causing the output voltage to rise.

The H11B2M-V optoisolator can also be used for low-voltage, low-power, and logic-level applications and it is suitable for digital signal and isolation related applications, such as interfacing high-voltage and/or low-voltage AC and DC power circuits to CPU/microprocessor systems. The device also provides electrical noise suppression and can route data and signals from one circuit to another circuit without introducing noise into the signal. Additionally, the optical isolation between the input and output terminals helps protect the system from interfering signals.

The H11B2M-V optoisolator is characterized by its low-current draw during operation; its low input to output creepage; and its high noise immunity and return current suppression. The optoisolator offers a wide variety of output resistance values, from 10 kilohm to 1 megohm, and its high input-output voltage capabilities range from 5 to 35 volts. The device can also provide fast switching speeds, with typical switching times ranging from 6 to 10 nanoseconds.

The H11B2M-V optoisolator is an excellent choice for applications requiring electrical isolation between two circuits. Its low current draw, low input to output creepage, high noise immunity and return current suppression make it highly reliable and efficient. Moreover, its wide variety of outputs, its ability to interface high-voltage and low-voltage AC and DC power circuits to CPU/microprocessor systems, and its fast switching speeds provide exceptional performance and versatility in design applications.
