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. There is no law governing all things. Muhammad Akhlaq on May 30, datzsheet 9: Better check the datasheet for a test circuit.

In my example an ohmmeter is connected at the output, in order to see the change in resistance. Michael on January 21, at 3: The question is which one is the right testing method?
What if there is photo-Triac instead of Photo-transistor, How to test then? I guess, it should work mostly the same as a normal triac. Ado on November 14, at But what i want to mention is there is a different testing circuit on the datasheet of H11B1.
Description EL Phototransistor Photocoupler The EL Phototransistor Photocoupler series of devices each consist of an infrared emitting diodes, optically coupled to a phototransistor detector.
If the input is at 2V DC, then the output resistance should be around — ohms. Hi, First of all thanks for sharing such an useful information.
Mihai on July 15, at 8: I appriciate… I tried that emprical method for H11B1 optocoupler. Evis on November 12, at 7: Opto – isolators prevent high voltages from affecting the system receiving the datasgeet.
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. Mohamed on October 9, 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 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 was referring to the junction resistance. Your email address will not be published. Nupra on March 18, at 6: The EL Phototransistor Photocoupler series of devices each consist of an infrared emitting diodes, optically coupled to a phototransistor detector.
An optocoupler or optoisolatoris a device that contains a light-emitting diode Dahasheet and a photosensor photodetector, such as a photoresistor, a photodiode, a phototransistor, …etc.
Thanks for the easy to follow explanation of how to rest an optocoupler. Here is the web site. El8817 only have a digital multi meter. Home appliances, such as fan heaters, etc.
