Introduction

The HCNR200#050 optoisolator, also known as a transistor, photovoltaic output optoisolator, is an electromechanical device designed to transfer information from low voltage to high voltage without direct electrical contact between the two circuits. It provides electrical isolation between input ("logic and/or signal level") and output ("high side drive") circuits. The device is a very reliable and cost-effective method of recovering information from difficult-to-access environments, and is suitable for both AC and DC operation.

Application Field

The HCNR200#050 optoisolator is ideal for applications using digital logic signals which require voltage levels, ranging from 3 volts to 48 volts from a single device. Applications using the device include electronic relays, solid state switching applications, small current logic sensing, motor control, security systems, motion control, electrical safety systems, circuit protection, optical isolation, signal and data transmitting and receiving, and pressure-sensitive switch signaling.Due to its small size, it can save board space by reducing the number of components in a complex system, especially in low-voltage applications. Furthermore, its ability to convert multiple signal types, such as low-voltage, high-voltage and optical signals into more usable forms, means that the device can be used as an interface between different systems. The HCNR200#050 is also suitable for other electrical applications including power management, static sensitive components, software control, automotive electronics, medical devices, smart appliances and consumer electronics.

Working Principle

The HCNR200#050 optoisolator works by using a low-voltage logic input to control a high active drive output. This happens by using an LED which is photovoltaically isolated from the input. When the LED is activated, it produces light which is detected by a photodiode on the other side of the device. The photodiode then produces an electrical current, which results in the activation of the output transistor. It essentially acts as a one-way switch with the input as the control signal and the output as an amplified version of the input signal. The output voltage and current are also proportional to the intensity of the output LED, which can be controlled with the input voltage. In the HCNR200#050 optoisolator, the LED can handle input voltages between 3 and 30V with a maximum of 30V peak. The output transistor is rated at up to 48V peak at 1A. The device is also able to provide an isolation of up to 2500Vrms, making it an excellent choice for industrial and consumer circuits.

Conclusion

The HCNR200#050 optoisolator from Vishay is an excellent choice for applications which require electrical isolation or signal conversion between low and high voltage levels. It is capable of providing an isolation of up to 2500Vrms, and is suitable for many digital logic and other electrical applications. Additionally, its small size and cost-effectiveness make it a great choice for complex systems or where board space is limited.
