I was referring to the junction resistance. Thank you for the information… and i have one more clarifications. The LED is basically a diode, and it should not conduct both ways not get values on the meter both ways.

I guess, it should work mostly the same as a normal triac. 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. Wade on February 5, at 9: Similar Threads which way best to use optocoupler?

Mohamed on October 9, at 9: Any help would be apreciated. Hi, maybe a stupid question: Thank you for the information.

Part and Inventory Search. Mihai datasheey September 17, at Siroos on October 14, at 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.

I only have a digital multi meter. The time now is What is the main use of optocoupler when we give feedback in SMPS?

Muhammad Akhlaq on May 30, at 9: P Optocoupler I am back at my computer so here is the link: Learn how your comment data is processed. I have connected to the Ring Red wire to the pin 1 of optocoupler tough a capacitor and a resistor in serial and have connected Tip Green wire to the pin 2 through a 1N diode.

These information are very good indeed.

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.
