Working Principle

The internal structure of the CNY17F-2X009 optoisolator consists of an integrated photo-transistor that is optically coupled to an emitter-base pair of LEDs. The device contains a Photodiode, an LED, and a MOSFET. When a signal is applied to the control input, the LED will be lit. The photons released by the LED are detected by the photodiode which turns it into an electrical signal. The electrical signal is then amplified by the MOSFET which allows the transistor output to control higher power devices. This optoisolator offers increased noise immunity and improved signal integrity due to the electrical isolation between circuits.
