cosmo datasheet & applicatoin notes – Datasheet Archive
Evis on November 12, at 7: The LED is basically a diode, and it should not conduct both ways not get values on the meter both ways. Sanu sebastian on August 19, at There is no law governing all things. With no voltage applied to the LED pins 1 and 2and with an open base pin 6there should be a high resistance between pins 5 and 4. Pls let me know.

Mohamed on October 9, at 9: The optocoupler is FL C F, should i just join the emittor and collector pins? 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.
Mihai on September 17, at How the optocoupler Type SFH acts when the positive line is open. Learn how your comment data is processed. Mihai on March 18, at It depends on the 2nd circuit you are supplying the voltage on collector of the optocoupler, optocoupler will never transfer the voltages of circuit1 to circuit2, it decreases resistance between your supplied voltages at collector and emitter on the input of circuit2. Siroos on October 14, at Hi, Both methods are correct.
Mihai on July 15, at 8: Emprical method you mention above or the testing circuit on the datasheet of H11B1?
Kannan E on July 19, at 9: But what i want to mention is there is a different testing circuit on the datasheet of H11B1. Sunil on March 3, at 3: Sarfaraz dataheet November 8, at 9: So when current flows through the LED, the triac is datasheeet and it conducts both ways until the main current drops below a certain level.
Mihai on July 16, at 5: 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.

Here is the web site. Step 2 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. csomo1010
How can i test them? I was referring to the junction resistance. The firehose by day and forty beers by night, An engineer may never sleep and still be just as bright. The alcohol never solved anything, but neither did water or milk.
These information are very good indeed. Cosmo10010 question is which one is the right testing method? I like the way you explain things. 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. Good design is as coso1010 design as possible.
