Optoisolators - Transistor, Photovoltaic Output

Optoisolators are devices used to electrically isolate a circuit by way of a physically separate, optically coupled device. They work by using a light emitting device or LED, along with a photosensitive collector, such as a photodiode or phototransistor. The H11AA2S(TA)-V optoisolator is a six pin surface mount device that works as an output transceiver with a photovoltaic isolation, providing electrical insulation between input and output circuits.

Working Principle

The H11AA2S(TA)-V optoisolator consists of an infrared source/emitter LED and photodiode in close physical proximity but isolated through a transparent molding. When the input is applied to the LED, it emits an infrared light that is coupled into the photodiode. The output of the photodiode is amplified by a transistor within the device, creating an output state that is proportional to the input state. This optoisolator is designed to provide LED to photodiode isolation up to 2500VRMS, and can provide single-bit data transmission up to 10Mbps. It is also designed to provide excellent electrical isolation without sacrificing response time. The H11AA2S(TA)-V optoisolator operates from 10V to 30V, with a low-level signal response of 2.2V minimum at 20mA. The power dissipation is typically 250mW max, with a maximum forward current of 20 mA.

Application Field

The H11AA2S(TA)-V optoisolator is suitable for use in many industrial applications, such as electronic circuitry for sensors, devices for data transmission, and control system isolators in industrial machinery. It is also useful for any optically coupled data or electrical signal isolation needs, providing regulated electrical current or voltage isolation up to 2500 VRMS. The H11AA2S(TA)-V optoisolator is particularly important for protecting sensitive electronics, as it effectively isolates electrical currents between input and output, providing preventative measures against power or data surges. It is an ideal choice for applications where there is a need for AC or DC circuit isolation. The H11AA2S(TA)-V optoisolator is also used in medical equipment, where patient safety and data protection are of paramount importance. It isolates data and electrical signals between two devices and can be used in computer technology where it largely helps in reducing EMI and noise emissions.

Conclusion

The H11AA2S(TA)-V optoisolator is an ideal device for providing data or electrical signal isolation, up to 2500 VRMS. It is designed with a low-level signal response of 2.2V minimum at 20mA, and can provide single-bit data transmission up to 10Mbps. The optoisolator helps protect sensitive electronics such as those used in medical equipment, and is used widely in industrial and computer applications for its ability to reduce EMI and noise emissions.
