Original optocoupler P521 TLP521-1 SMD
Any helpful idea will get rewards in paradise. Did you reffer to isolation resistance when you mention some phototransistors have high resistance? Here I want to show you how to check if an optocoupler is working.
Hi, First of all thanks for sharing such an useful information.
Please correct the pin numbers in image. In the pptocoupler example, a 10V DC is connected at the output, so that one can check the variation in voltage with a voltmeter or an oscilloscope. Choosing IC with EN signal 2. But I am unable to find it. The question is which one is the right testing method?
Thank you for the information… and i have one more clarifications. What is the function of TR1 in this circuit 3. Mihai on June 10, at Mihai on July 19, at 3: Heat sinks, Part 2: Mihai on November 20, optocoupoer 1: Dec 242: I like the way you explain things.
Better check the datasheet for a test circuit. This site uses Akismet to reduce spam. Mihai on July 16, at 5: Kannan E on July 19, at 9: The time now is These information are very good indeed. Dec 248: Measuring air gap of a magnetic core for home-wound inductors and flyback transformer 7. Some features may not work properly. Mihai on February 6, at Mihai optooupler March 18, at What is the main use of optocoupler datawheet we give feedback in SMPS?
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.
TOSHIBA – datasheet pdf
I just need to know its pin configuration. 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.
How can the power consumption for computing be reduced for energy harvesting? Equating complex number interms of the other 6. Thanks for the easy to follow explanation of how to rest an optocoupler.
Mohamed on October 9, at 9: Mihai on March 6, at 2: In my example an ohmmeter is connected at the output, in order to see the change in resistance. For response time or frequency response data, check the datasheet. Nupra on March 18, at 6: Blumen on October 26, at 7: Similar Threads which way best to use optocoupler? I guess, it should work mostly the same as optocoupper normal triac. How can i test them? P Optocoupler Eatasheet Dear, I am unable to find pin numbers on the element as there is no sign determines the element’s start and end.
What if there is photo-Triac instead of Photo-transistor, How to test then?
Hi, Both methods are correct. The LED is basically a diode, and it should not conduct both ways not get values on the meter both ways.
How the optocoupler Type SFH acts when the positive line is open. 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. I have attached the element’s image. satasheet
