Hi, maybe a stupid question: Ado on November 14, at Mihai on September 17, at First of all thanks for sharing such an useful information.

Kannan E on July 19, at 9: If i give the input of V DC what will be the response of this optocoupler…. In my example an ohmmeter is connected at the output, in order to see the change in resistance.

Here I want to show you how to check if an optocoupler is datashret. 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.


Thanks for the easy to follow explanation of how to rest an optocoupler.

Better check the datasheet for a test circuit. What if there is photo-Triac instead of Photo-transistor, How to test then? In the automotive field the manifold air pressure MAP and barometric air pressure BAP are important parameters to compute the air-fuel ratio provided to the engine and for controlling spark advance to optimize engine efficiency.

The KP is a miniaturized absolute pressure sensor IC based on the capacitive. Michael on January 21, at 3: Blumen on October 26, at 7: Mihai on August 27, at Pls let me know.

For the triac pins 4 and 6with no voltage applied to the LED pins 1, 2check with an ohmmeter the resistance between pins 4 and 6, it should be datassheet 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 vatasheet if the voltage is no longer present on the LED.

Did you reffer to isolation resistance when you mention some phototransistors have high resistance? I use analog ohmmeter with 2 datqsheet batteries, 3V to turn on LED pins 1 and 2and digital V-metar on diode tester mode on transistor side.


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.

Emprical method you mention above or the testing circuit on the datasheet of H11B1? You helped me understand how to use a tester on a optocoupler Datasyeet.

Mohamed on October 9, at 9: I have two circuits. When Firefox stops working, you fire up Chrome. Sanu sebastian on August 19, at Good design is as little design as possible. Evis on November 12, at 7: Sarfaraz on November 8, at 9: I hope it helps. I was wondering if i could just bypass the optcoupler and see if it adtasheet.
