If the input is at 2V DC, then the output resistance should be around — ohms.
Your email address will not be published. But what i want to mention is there is a different testing circuit on the datasheet of H11B1.

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. Mihai on November 20, at 1: The problem is, that I’m not quite sure if this optocoupler can be used for this circuit. I think that the maximum ratings are acceptable but maybe I’m missing some details.
Mihai on August 27, at The LED is basically a diode, and it should not conduct both ways not get values on the meter both ways.
Hi, maybe a stupid question: Mihai on October 28, at 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. Thanks for the clarification. Please correct the pin numbers in image.
Pls let me know. Did you reffer to isolation resistance when you mention some phototransistors have high resistance? For response time or frequency response data, check the datasheet.

Evis on November 12, at 7: In my example an ohmmeter is connected at the output, in order to see the change in resistance. There is no law governing all things. Thx and best regards, Geert. However, this is nothing I would recommend you rely on.
I like the way you explain things. Ado on November 14, at The alcohol never solved anything, but neither did water or milk.
Thanks for the easy to follow explanation of how to rest an optocoupler. Leave a Reply Cancel reply Your email address will not be published.
I was referring to the junction resistance. Mihai on July 19, at 3: Shahid on August 7, at 1: This is the schematic as shown by the MIDI specification: Some features may not work properly. Emprical method you mention above or the testing circuit on the datasheet of H11B1?
To do that, I need an optocoupler, that secures the internal circuits from damage.
Better check the datasheet for a test circuit.
