Optoisolators - Transistor, Photovoltaic Output

Optoisolators, also known as opto-couplers, photocouplers, optical couplers, and opto-isolators are electrical components that couple two circuits together optically. One of these components is the VO617A-3X016 Optocoupler, a transistor output coupler designed to isolate low-voltage digital logic signals from high-voltage applications. This article will discuss the application field and working principle of the VO617A-3X016 Optocoupler.

Application Field and Environment

The VO617A-3X016 is useful in a wide range of applications encompassing a variety of industry-specific requirements. These applications include motor controllers, home and office automation, solar panel and inverter systems, real-time switchgear equipment, industrial lighting, HVAC/R systems, semiconductor testing equipment, ultrasound imaging equipment, and medical equipment. Furthermore, the VO617A-3X016 is designed for working in dynamic environments and features an operating temperature range between -40°C to +125°C.

Components and Working Principle

The VO617A-3X016 comprises of a single IC chip, sealed in a package, and isolated from its supply voltage by an internal glass plate. A photodiode, whose function is to convert light signals into electrical signals, is located on the front side of the IC chip. The backside of the chip contains a transistor, which connects to an output terminal. The working principle of this device is based on the idea of optical isolation. When a current is applied to the photodiode, it emits light, which is then reflected off the internal glass plate and focused onto the transistor. The light on the transistor causes it to switch on, allowing current to flow between the output terminal and the control terminal. This isolates the input signal from any external noise or electrical interference.The VO617A-3X016 also contains a number of protective features, such as overvoltage protection, a 200 V rms transient voltage protection rating, and a built-in shield for added protection from electrical noise and EMI. This makes it suitable for applications that require reliability and a high level of immunity to noise.

Conclusion

The VO617A-3X016 optocoupler is designed for isolating low-voltage digital signals from high-voltage applications, and is suitable for a variety of industry-specific requirements. Its internal structure consists of a photodiode, which converts light signals into electrical signals, and a transistor, which connects to an output terminal. Its optical isolation design provides protection from external noise and electrical interference, and it also features a number of protective features to ensure reliability and a high level of immunity to noise.
