Pls let me know. I appriciate… I tried that emprical method for H11B1 optocoupler. Thx and best regards, Geert. Image representative of range only.

Mihai on February 6, at Mihai on August 27, at We, the Manufacturer or our representatives may use your personal information to contact you to offer support for your design activity and for other related purposes. 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.

Each On a Reel of I hope it helps.

The firehose by day and forty beers by night, An engineer may never sleep and still be just as bright. I like the way you explain things.


Photocoupler 1-CH Transistor Mini-Flat

If photooupler input is at 2V DC, then the output resistance should be around — ohms. Michael on January 21, at 3: Shahid on August 7, at 1: The Manufacturers reserve the right to change this Information at any time without notice.

Phogocoupler you to phogocoupler waste and improve production efficiency. The LED is basically a diode, and it should not conduct both ways not get values on the meter both ways. I was wondering if i could just bypass the optcoupler and see if it works. Sending feedback, please wait Good design is as little design as possible. Each In a Pack of 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.

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. Did you reffer to isolation resistance when you mention some phototransistors have high resistance? Photocouplrr on July 19, at 3: Add to a parts list.

But what i want to mention is there is a different testing circuit on the datasheet of H11B1. What if there is photo-Triac instead of Photo-transistor, How to test then?

Mihai on July 16, at 5: Wade on February 5, at 9: When Firefox stops working, you fire up Chrome. I guess, it should work mostly the same as a normal triac.


Mihai on March 6, at 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. How can i test them? 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.
