CNY17x, SFH61xA, TCET110x, or K817P family.

Opto coupler are designed to provide complete electrical isolation between an input and output circuits.

The useful purpose of isolation is to provide protection from high voltage, surge voltage and low level noises that could be produces errors in the output. Optocouplers also provides interface between different voltage . An optocoupler (or an optoelectronic coupler) is basically an interface between two circuits which operate at (usually) different voltage levels. The key advantage of an optocoupler is the electrical isolation between the input and output circuits.

With an optocoupler , the only contact between the input and the . If you enjoy watching my videos, please show your support by SUBSCRIBING,. How to identify your optocoupler pin details with Digital Multimeter? The 4Nfamily is an industry standard single channel phototransistor coupler.

Markus Appel, Application Engineer and Achim M. Each optocoupler consists of gallium. It is determined by the light emission efficiency of the IRE the efficiency of light transmission between the IRED and the phototransistor, the light sensitivity of the phototransistor, and the hFE of the transistor. Using the diagram in the right . A description of the process of testing and implementing on optocoupler or optoisolator in specific the 4N25. Optoisolator IC allows two circuits to exchange signals yet remain electrically isolated.

The phototransistor acts as an output device while the LED acts as an input device. It is also called Photocoupler or Optoisolator. Quad Channel, SOP-1 Half Pitch Mini-Flat Package. This model number should be used when consulting safety agency documents. UL, accordance to CSA component acceptance service no.

The safety application model number covering all products in this datasheet is SFH617A. The coupling device is suitable for signal transmission between two . Linear mode and digital logic mode.
