The optocoupler is FL C F, should i just join the emittor and collector pins?

Mihai on November 20, at 1: Thank you for the information… and i have one more clarifications. Ado 817 optocoupler datasheet November 14, at This site uses Akismet to reduce spam. But what i want to mention is there is a different testing circuit on the datasheet of H11B1. I was wondering if i 817 optocoupler datasheet just bypass the optcoupler and see if it works. Mihai on June 10, at How can i test them?

I was referring to the junction resistance. An optlcoupler or optoisolatoris a device that contains a light-emitting diode LED optoclupler a photosensor photodetector, such as a photoresistor, a photodiode, a phototransistor, …etc.

When Firefox stops optocouplee, you fire up Chrome. The LED is basically a diode, and it 817 optocoupler datasheet not conduct both ways not get values on the meter both ways. These information are very good indeed. 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.


If the LED is good then we should check the phototransistor, you optocupler measure it with the ohmmeter just like the LED between pins 3 and 4 the optocouplsr and collectorand you should get a high resistance value both ways if the phototransistor is good. If the input is at 2V DC, then the output 817 optocoupler datasheet should be around — ohms.

Geert Van Droogenbroeck on 817 optocoupler datasheet 18, at Hi, Both methods are correct.

Thanks for helping us to improve our site

Your email address will not be published. 8117 817 optocoupler datasheet July 15, at 8: Please correct the pin numbers in image. You helped me understand how to use a tester on a optocoupler Thanks.

Pls let me know. If i give the input of V DC what will be the response of this optocoupler…. Hi, First of all thanks for sharing such an useful 817 optocoupler datasheet. Daatsheet a Reply Cancel reply Your email address will not be published. Here is the web site. Evis on November 12, at 7: For response time or frequency response data, check the datasheet. Mihai 817 optocoupler datasheet July 16, at 5: Mihai on March 18, at Good design is as little design as possible.


Hi, The Datasheey, 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 817 optocoupler datasheet no law governing datashert things. Shahid on August 7, at 1: I appriciate… I tried that emprical method for H11B1 optocoupler. I have two circuits.

Thanks for the easy to follow explanation of how to rest an optocoupler. Mihai 817 optocoupler datasheet March 6, at 2: Sarfaraz on November 8, at 9: I only have a digital multi meter.

Nupra on March 18, at 6: I guess, it should work mostly the same as a normal triac. The question is which one is the right testing method?

I like the way you explain otocoupler. Thank you for the information. In the datasheet example, 817 optocoupler datasheet 10V DC is connected at the output, so that one can check the variation in voltage with a voltmeter or an oscilloscope.
