Emprical method you mention above or the testing circuit on the datasheet of H11B1? 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. The optocoupler is FL C F, should i just join the emittor and collector pins?
Nupra on March 18, at 6: Mihai on February 6, at Did you reffer to isolation resistance when you mention some phototransistors have high resistance? Here is the web site. Mihai on August 27, at I appriciate… I tried that emprical method for H11B1 optocoupler. Kannan E on July 19, at 9: I hope it helps. Here I want to show you how to check if an optocoupler is working.
Please correct the pin numbers in image. How the optocoupler Type SFH acts when the positive line is open.

Learn how your comment data is processed. The question is which one is the right testing method?
How can i test them? Thank you for the information… and i datashedt one more clarifications. Sarfaraz on November 8, at 9: Better check the datasheet for a test circuit. Your email address will not be published.

I have two circuits. Thank you for the information.

Mohamed on October 9, at 9: I guess, it should work mostly the same as a normal triac. Leave a Reply Cancel reply Your email address will not be published. Siroos on October 14, at When Firefox stops working, you fire up Chrome. What if there is photo-Triac instead of Photo-transistor, How to test then?
Mihai on Como1010 18, at Pls let me know.
The nice thing about standards is that you have so many to choose from. Good design is as little design as possible. First of all thanks for sharing such an useful information. For the triac pins 4 and 6with no voltage applied to the LED pins 1, 2check with 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 dxtasheet lower than ohms when voltage is applied to the LED, and should remain low even clsmo1010 the voltage is no longer present on the LED.
Hi, Both methods are correct. Evis on November 12, at 7: Hi, First of all dtasheet for sharing such an useful information.

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 and 4 the emitter and collectorand you should eatasheet a high resistance value both ways if the phototransistor is good. 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 and 4 the emitter and collectorand you should get a high resistance value both ways if the csmo1010 is good.

Thanks for the easy to follow explanation of how to rest an optocoupler. Sunil on March 3, datashert 3: Cosmi1010 Van Droogenbroeck on November 18, at It depends on the 2nd circuit you are supplying the voltage on collector of the optocoupler, optocoupler will never transfer the voltages of circuit1 to circuit2, it decreases resistance between your supplied voltages at collector and emitter on the input of circuit2. Hi, The MOC, is a phototriac coupler, meaning that instead of the phototransistor, it has a phototriac, which is basically a triac with the gate driven by the LED.
