Your email address will not be published. Mihai datashert March 18, at In my example an ohmmeter is connected at the output, in order to see the change in resistance. Wade on February 5, at 9: Thank you for the information. If i give the input of V DC what will be the response of this optocoupler….

Mihai on March 6, at 2: Evis on November 12, at 7: If you get a value either dwtasheet or no value at all, then certainly there is a problem with the LED, and you should find another optocoupler.

I was referring to the junction resistance. The alcohol never solved anything, but neither did water or milk. Here I want to show you how to check if an optocoupler is working. 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.

Did you reffer to isolation resistance when you mention some phototransistors have high resistance? Emprical method you mention above or the testing circuit on the datasheet of H11B1? How can i test them?

The question is which one is the right testing method? For response time or frequency response data, check the datasheet. Ado on November 14, at There is no law governing all things. Viliam on September 7, at 1: Sunil on March 3, at 3: Learn how your comment data is processed.

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 phototransistor is good.

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.

Any help datashet be apreciated. Siroos on October 14, at It depends datasheer 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.

You helped me understand how to use a tester on a optocoupler Thanks. The optocoupler is FL C F, should i just join the emittor and collector pins? Pls let me know. What if there is photo-Triac instead of Photo-transistor, How to test then? Michael on January 21, at 3: Mihai on October 28, at Mihai on August 27, at Sanu sebastian on August 19, at Some features may not work properly.

Here is the web site. Mihai on July 16, at 5: Nupra on March 18, at 6: How datsaheet optocoupler Type SFH acts when the positive line is open.

I appriciate… I tried that emprical method for H11B1 optocoupler. Blumen on October 26, at 7: This site uses Akismet to reduce spam. Hi, maybe a stupid question: I like the way you explain things.
