How to test an optocoupler – AntiMath

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 even if the voltage is no longer present on the LED.

Hi, Both methods are correct. Mihai on September 17, at Mihai on March 6, at 2: Mihai on July 15, at 8: Sanu sebastian on August 19, at Your email address will not be published. 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.

There is no problem with the absolute maximum ratings.

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. I only have a digital multi meter.

Mihai on July 16, at 5: Nupra on March 18, at 6: I was referring to the junction resistance. Pcc123 no voltage applied to the LED pins 1 and 2and with an open base pin 6there should be a high resistance between pins 5 and 4. Here is the web site. Good design is as little design as possible.

The question is which one is the ;c123 testing method? There is no law governing all things. The MIDI specification calls for a p123 optocoupler.

If the input is at 2V DC, then the output resistance should be around — ohms.

IMO it shall work without any problem. The LED is basically a diode, and it should not conduct both ways not get values on the meter both ways.

I use analog ohmmeter with 2 internal batteries, 3V to turn on Pc12 pins 1 and 2and digital V-metar on diode tester mode on transistor side. Sunil on March 3, at 3: You helped me understand how to use a tester on a optocoupler Thanks. Pls let me know.

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 pc1233 emitter and collectorand you should get a high resistance value both ways if the phototransistor is good.

This is the schematic as shown by the MIDI specification: Michael on January 21, at 3: However, there might pv123 problems with the other parameters of this optocoupler. With the Arduino’s Schmitt trigger inputs, and a portion of luck, you might actually pc132 able to get the signal out, so you might as well try it. 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 purpose of an optocoupler is to transfer signals from one circuit to another yet keep them galvanically isolated.
