Mihai on October 28, 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.
Nupra on March 18, at 6: Pls let me know. If i give the input of V DC what will be the response of this optocoupler….
Mihai on July 19, at 3: Mihai on August 27, at If you get a value either way or no value at all, then certainly there is dataaheet problem with the LED, and you should find another optocoupler. There is no law governing all things. Sanu sebastian on August 19, at Ado on November 14, at Mohamed on October 9, at 9: The firehose by day and forty beers by night, An engineer may never sleep and still be just as bright.
Thank you for the information. Arvind Vijaykumar on June 1, at I was referring to the junction resistance.
Learn how your comment data is processed. Please correct the pin numbers in image.
Thx and best regards, Geert. Siroos on October 14, at I like the way you explain things.

Step 2 If the LED is good then we should check the phototransistor, you could measure it with daatasheet 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.
Shahid on August 7, at 1: Mihai on July 15, at 8: Better check the datasheet for a test circuit.
Hi, First of all thanks for sharing such an useful information. Michael on January 21, at 3: The LED is basically a diode, and it should not conduct both ways not get values on the meter both ways.

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 dxtasheet. Wade on February 5, at 9: How the optocoupler Type SFH acts when the positive line is open. You helped me understand how to use a tester on a optocoupler Thanks. Mihai on November 20, at 1: 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.

Mihai on July 16, at 5: The purpose of an optocoupler is to transfer signals from one circuit to another yet keep them galvanically isolated. Muhammad Akhlaq on May 30, at 9: Evis on November 12, at 7: These information are very good indeed. Mihai on September 17, at Hi, maybe a stupid question: I have two circuits.
