Optocouplers are a type of optoelectronic device used to transfer electrical signals between two isolated circuits. They are used in a variety of applications, such as motor control, power supplies, and industrial automation. Optocouplers are composed of a light-emitting diode (LED) and a photodetector, such as a phototransistor, photodiode, or photoresistor. The LED emits light which is detected by the photodetector, allowing the electrical signal to be transferred between the two circuits. Optocouplers are widely used in the industrial and automotive sectors, as well as in consumer electronics. They are used to provide electrical isolation between two circuits, allowing them to operate independently while still transferring signals. This helps to reduce the risk of electrical interference and damage to sensitive components. The optocoupler market is highly competitive, with a number of companies offering a range of products. Some of the major players in the market include Vishay Intertechnology, Toshiba, NXP Semiconductors, STMicroelectronics, and Avago Technologies. Show Less Read more
