If you get a value either way or no value at all, then certainly there is a problem with the LED, and you should find another optocoupler. Thanks for the easy to follow explanation of how to rest an optocoupler. Hi, First of all thanks for sharing such an useful information. Mihai on November 20, at 1: Good design is as little design as possible. Kannan E on July 19, at 9: An optocoupler or optoisolatoris a device that contains a light-emitting diode LED and a photosensor photodetector, such as a photoresistor, a photodiode, a phototransistor, …etc.

Mihai on June 10, at These information are very good indeed. Step 2 If the LED is good then we should check the phototransistor, you could measure it with the ohmmeter just like the LED between pins 3 datassheet 4 the emitter and collectorand you should get a high resistance value both ways if the phototransistor is good.

Mihai on July 19, at 3: Here I want to show you how to check if an optocoupler is working. Mihai on July 15, at 8: Thx and best regards, Geert. There is no law governing all things. For response time or frequency response data, check the datasheet. Viliam on September 7, at 1: Shahid on August 7, at 1: Please correct the pin numbers in image.

The purpose of an optocoupler is to transfer signals from one circuit to another yet keep them galvanically isolated. Mihai on February 6, at Your email address will not be published.

Wade on February 5, at 9: The nice thing about standards is that you have so many to choose from. Some features may not work properly. Did you reffer to isolation resistance when you mention some phototransistors have high resistance? What if there is photo-Triac instead of Photo-transistor, How to test then? Mihai on March 6, at 2: I like the way you datzsheet things.

If the input is at 2V DC, then the output resistance should be around — ohms. The alcohol never solved anything, but neither did water or milk. datssheet

Arvind Vijaykumar on June 1, at With no voltage applied to the LED pins 1 and 2daatsheet with an open base pin 6there should be a high resistance between pins 5 and 4. How the optocoupler Type SFH acts when the positive line is open.

Nupra on March 18, at 6: You helped me understand how to use a tester on a optocoupler Thanks. Pls let me know.

Thank you for the information. Hi, maybe a stupid question:
