Optoisolators - Transistor, Photovoltaic Output

Optoisolators are electrical components that provide electrical isolation between two different circuits. An optoisolator consists of a light source, typically an LED (light emitting diode), and a photosensitive device, usually a phototransistor or photodarlington. When the light emitted from the LED is received by the phototransistor or photodarlington, the transfer of electrical signals occurs without any direct contact between the two circuits. This allows the isolated circuit electric current to be safely contained in the optoisolator and not interrupt the operation of any other electronics on the same board.

CNY17-2. Application Field and Working Principle

Optoisolators are used in both industrial and consumer electronics. In the industrial sector, optoisolators are used to protect expensive and delicate devices from over-voltage, short circuits, ESD (electrostatic discharge), and ground loops. In consumer electronics, optoisolators are often used in PC motherboards, keyboards, and gaming consoles to protect them from the dangers of uncontrolled electrical surges. Optoisolator\'s working principle is relatively simple. When an incoming voltage is applied to the input of the optoisolator, the LED emits light of a specific intensity, which is proportional to the incoming voltage. This light energy is then transferred to the phototransistor or photodarlington, causing it to conduct or switch the output voltage. The advantage of this method is that the output voltage is isolated from the input voltage, preventing dangerous over-voltage that can damage delicate electronics. The CNY17-2 optoisolator is a non-zero-crossing optoisolator. The output responds output when the input voltage is higher than 0.7V and the current is 5mA or greater. This optoisolator is designed to be used in AC loads where the current must cross zero. It can be used to control typical AC loads such as light bulbs, motors, and solenoids. Its maximum voltage isolation is 3000V and the output is capable of 200mA at 55°C. The CNY17-2 is widely used in electronic control boards such as computer power supplies, UPSs, and HVAC systems. Using the optoisolator here helps to protect against unwanted surges or shorts. The CNY17-2 is also used in medical equipment, automotive controls, and consumer electronic applications. This optoisolator is available in both surface mount and through-hole packages. Depending on the application, it can be used in either protection or signal isolation modes. The optoisolator is extremely reliable and is capable of a long life of 20,000 hours at 55°C. In conclusion, optoisolators are a high performance and cost-effective solution for isolating two circuits and providing protection from dangerous voltages. The CNY17-2 optoisolator is an excellent choice for applications requiring zero-crossing detection, with its long running time, high voltage isolation, and simple control.
