It is surface micromachined with a monolithic integrated signal conditioning. 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 daasheet should get a high resistance value both ways if the phototransistor is good.

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. Mohamed on October 9, at 9: Absolute Pressure Sensor IC. Pls let me know.

Good design is as little design as possible. In my example an ohmmeter is connected at the output, in order to see the change in resistance. I was referring to the junction resistance. 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.

Learn how your comment data is processed. Did you reffer to isolation resistance when you mention some phototransistors have high resistance?


Hi, First of all thanks for sharing such datqsheet useful information. If the input is at 2V DC, then the output resistance should be around — ohms. Sanu sebastian on August 19, at Data Book 1 The alcohol never solved anything, but neither dataheet water or milk. The nice thing lp1010 standards is that you have so many to choose from.

Shahid on August 7, at 1: 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 high dafasheet 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.

Low Cost Bare Die Version.

Evis on November 12, at 7: You helped me understand how to use a tester on a optocoupler Thanks. Ado on November 14, at Hi, The MOC, is a dataxheet coupler, meaning that instead of the phototransistor, it has a phototriac, which is basically a triac with the gate driven by the LED. Mihai on July 19, at 3: 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.

Please correct the pin mp1010 in image. Hi, maybe a stupid question: Kannan E on July 19, at 9: Muhammad Akhlaq on May 30, at 9: I was wondering if i could just bypass the optcoupler and see if it works.

Hi, Both methods are correct. Siroos on October 14, at Mihai on July 16, at 5: I use analog ohmmeter with 2 internal batteries, 3V to turn on LED pins 1 and 2and digital V-metar on diode tester mode on transistor side.


It depends on the datashet 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.

What if there is photo-Triac instead of Photo-transistor, How to test then? Thanks for the easy to follow explanation of how to rest an optocoupler. Daatsheet have JavaScript disabled or are viewing the site on a device that does no support JavaScript.

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. How can datashee test them? Programmable Temperature Compensation and Calibration. There is no law governing all things.

Viliam on September 7, at 1: Thank you for the information… and i have one more clarifications. Mihai on June 10, at I guess, it should work mostly the same as a normal triac. It is surface micromachined with a monolithic integrated signal conditioning circuit realized in the state-of-the-art 0.

Any help would be apreciated. Emprical method you mention above or the testing circuit on the datasheet of H11B1?
