With no voltage applied to the LED pins 1 and 2and with satasheet open base pin 6there should be a high resistance between pins 5 and 4.

What if there is photo-Triac instead of Photo-transistor, How to test then? For response time or frequency response data, check the datasheet. 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 March 18, at Mihai on July 15, at 8: 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 down lower than ohms when voltage is applied to the LED, and should remain low cosml1010 if the voltage is no longer present on the LED.

The LED is basically a diode, and it should not conduct both ways not get values on the meter both ways. Leave a Reply Cancel reply Your email address cosmo10100 not be published.

Nupra on March 18, at 6: Learn how your comment data is processed. When Firefox stops working, you fire up Chrome. I like the way you explain things.

Mihai on June 10, at Sunil on March 3, at 3: Better check the datasheet for a test circuit. Mihai on October 28, at Some features may not work properly. 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.

The firehose by day and forty darasheet by night, An engineer may never sleep and still be just as bright.

Geert Van Droogenbroeck on November 18, at In my example an ohmmeter is connected at the output, in order to see the change in resistance. I only have a digital multi meter. Here I want to show you how to check if an optocoupler is working.

Mihai on February 2, at 5: Kannan E on July 19, at 9: 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.

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. How the optocoupler Type SFH acts when the positive line is open. You helped me understand how to use a tester on datasueet optocoupler Thanks. Hi, Both methods are correct.

Thx and best regards, Geert.

Thank you for the information… and i have one more clarifications. Hi, First of all thanks for sharing such an useful information.

Pls let me know. 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. Good design is as little design as possible.

Michael on January 21, at 3: There is no law governing all things. Muhammad Akhlaq on May 30, at 9: The optocoupler is FL C F, should i just join the emittor and collector pins? An optocoupler or optoisolatoris a device that contains a light-emitting diode LED and a dtasheet photodetector, such as a photoresistor, a photodiode, a phototransistor, …etc.

The alcohol never solved anything, but neither did water or milk. Sarfaraz on November 8, at 9: Wade on February 5, at 9: Hi, maybe a stupid question: If i give the input of V DC what will be the response of this optocoupler….

These information are very good indeed. I appriciate… I tried that emprical method for H11B1 optocoupler. Viliam on September 7, at 1: Mohamed on October 9, at 9: Mihai on March 6, at 2: Ado on November 14, at Here is the web site. 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 dataaheet between your supplied voltages at collector and emitter on the input of circuit2.
