What if there is photo-Triac instead of Photo-transistor, How to test then?


For response time or frequency response data, check the datasheet. The nice thing about standards is that you have so many to choose from. I only have a digital multi meter. Here is the web site.

Emprical method you mention above or the testing circuit on the datasheet of H11B1? Here I want to show you how to check if an optocoupler is working.


Sanu sebastian on August 19, at For the triac pins 4 and 6with no voltage applied to the LED pins 1, 2check oltocoupler an ohmmeter the resistance between pins 4 and 6, it should be high open circuit or at least greater than 1 megohm both ways, and this resistance should go down lower than ohms when voltage is applied to the LED, and should remain low even if the voltage is no longer present on the LED.

How can i test them?

Please correct the pin numbers in image. There is no law governing all things.

How the optocoupler Opgocoupler SFH acts when the positive line is open. Mihai on August 27, at Mihai on November 20, at 1: Mihai on February 6, at Leave a Reply Cancel reply Your email address will not be published. I guess, it should work mostly the same as a normal triac.

The purpose of an optocoupler is to transfer signals from one circuit to another yet keep them galvanically isolated. If the input is at 2V DC, then the output resistance should be around — ohms. Shahid on August 7, at 1: Mihai on June 10, at Evis on November 12, at 7: Thank you for the information.


The question is which one is the right testing method? Blumen on October 26, at 7: Mihai on September 17, at First of all thanks for sharing such an useful information. Mihai on March 6, at 2: Hi, First of all thanks for sharing such an useful information.

Mihai on October 28, at Sunil on March 3, at 3: Wade on February 5, at 9: The optocoupler is FL C F, should i just join the emittor and collector pins? Learn how your comment data is processed. Sarfaraz on November 8, optocoupker 9: Thanks for the easy to follow explanation of how to rest an optocoupler.
