For response eel817 or frequency response data, check the datasheet. Ado on November 14, at Applications of EL Phototransistor Photocoupler: Mihai on February 2, at 5: Mihai on February 6, at How the optocoupler Type SFH acts when the positive line is open. Shahid on August 7, at 1: Emprical method you mention above or the testing circuit on the datasheet of H11B1?

Mihai on August 27, at Compact small outline package. Mihai on November 20, at 1: 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. For the triac pins 4 and 6with no voltage applied to the LED pins 1, 2check with datasehet 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.

Your email address will not be published. A photocoupler, or optical isolator or an opto – isolator is a component that transfers electrical signals between two isolated circuits by using light.

EL series of devices are Photo transistor based photo coupler. I have two circuits.

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. Mohamed on October 9, at 9: Any help would be apreciated. Some features may not work properly. The question is which one is the right testing method?

Pls let me know. I was referring to the junction resistance. This site uses Akismet to reduce spam. An opto-isolator connects input and output sides with a beam of light modulated by input current. Sarfaraz on November 8, at 9: The optocoupler is FL C El8817, should i just join the emittor and collector pins?



The firehose by day and forty beers by night, An engineer may never sleep and still be just as bright. Enter the code in the box below. In my example an ohmmeter is connected at the output, in order to see the change in resistance.
