The purpose of an optocoupler is to transfer signals from one circuit to another yet keep them galvanically isolated. So when current flows through the LED, the triac is triggered and it conducts both ways until the main current drops below a certain level. For response time or frequency response data, check the datasheet.

Muhammad Akhlaq on May datasheett, at 9: Thank you for the information… and i have one more clarifications. Kannan E on July 19, at 9: Your email address will not be published. Sanu sebastian on August 19, at Learn how your comment data is processed.

Mohamed on October 9, at 9: Emprical method you mention above or the testing circuit on the datasheet of H11B1? Wade on February 5, at 9: Any help would be apreciated.


Mihai on September 17, at The optocoupler is FL C F, should i just join the emittor and collector pins? I appriciate… I tried that emprical method for H11B1 optocoupler. Michael on January 21, at 3: Mihai on March 18, at Siroos on October 14, at How the optocoupler Type SFH acts when the positive line is open.

In my example an ohmmeter is connected at the output, in order to see the change in resistance. 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 November datassheet, at 1: Here is the web site. 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. Evis on November 12, at 7: I have two circuits.

The LED is basically a diode, and it should not conduct both ways not get values on the meter both ways. You have JavaScript disabled or are viewing the site on a device that does no support JavaScript. I guess, it should work mostly the same as a normal triac. Datasheef, maybe a stupid question: First of all thanks for sharing such an useful information.

Blumen on October 26, at 7: Here I want to show you how to check if an optocoupler is working. Arvind Vijaykumar on June 1, at I was wondering if i could just bypass the optcoupler and see if it works. The firehose by day and forty beers by night, An engineer may never sleep and still be just as bright. Ado on November 14, at When Firefox stops working, you fire up Chrome. Good design is as little design as possible.

Viliam on September 7, at 1: In the datasheet example, a 10V DC is connected at the output, so that one can check the variation in voltage with a voltmeter or an oscilloscope. Mihai on August 27, at I use analog ohmmeter with 2 internal batteries, 3V to turn on LED pins 1 and 2and digital V-metar on diode tester mode on transistor side.
