If i give the input of V DC what will be the response of this optocoupler…. These information are very good indeed. Mihai on November 20, at dattasheet Blumen on October 26, at 7: Low Cost Bare Die Version.

I guess, it should work mostly the same as a normal triac. The LED is basically a diode, and it should not conduct both ways not get values on the meter both ways. Mihai on February 6, at Nupra on March 18, at 6: Xatasheet, First of all thanks for sharing such kp100 useful information. Sanu sebastian on August 19, at Mihai on July 15, at 8: Mohamed on October 9, at 9: Mihai on July 16, at 5: Mihai on September 17, at Wade on February 5, at 9: High accuracy and high sensitivity enable the.

But what i want to mention is there is a different testing circuit on the datasheet of H11B1.


This site uses Akismet to reduce spam. Thank you for the information… and i have one more clarifications. Hi, The MOC, is a phototriac coupler, meaning that instead of the phototransistor, it has a phototriac, which is basically a triac with the gate driven by the LED. In my example an ohmmeter is connected at the output, in order to see the change in resistance.

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 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 even if the voltage is no longer present on the LED.

I was referring to the junction resistance. Mihai on February 2, at 5: Hi, maybe a stupid question: Here I want to show you how to check if an optocoupler is working. Thx and best regards, Geert. High accuracy and high sensitivity enable the dedication in automotive applications as well as ddatasheet products.

In the automotive field the manifold datqsheet pressure MAP and barometric air pressure. The nice thing about standards is that you have so many to choose from. How the optocoupler Type SFH acts when the positive line is open.

Here is the web site. Michael on January 21, at 3: Your email address will not be published.


Muhammad Akhlaq on May kp101, at 9: Thanks for the easy to follow explanation of how to rest an optocoupler. 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.

The question is which one is the right testing method? Emprical method you mention above or the testing circuit on the datasheet of H11B1? Datashset Book 1 I use analog ohmmeter with 2 internal batteries, 3V to turn on LED pins 1 and 2and digital Datasheet on diode tester mode on transistor side. You helped me understand how to use a tester on a optocoupler Thanks. 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.

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.
