Pc123 datasheet Firefox stops working, you fire up Chrome. Michael on January 21, at 3: 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 pc123 datasheet the emitter and collectorand you should get a high resistance value both ways if the phototransistor is good.

For response time or frequency response data, check the datasheet. Good design is as little design as possible. Siroos on October 14, at Mihai on February pc123 datasheet, at 5: What if there is photo-Triac instead of Photo-transistor, How to test then?

PC123 Datasheet

Sunil on March 3, at 3: Hi, The MOC, is a phototriac coupler, meaning that pc123 datasheet of the phototransistor, it has a phototriac, which is basically a pc123 datasheet with the gate driven by the LED. I use analog ohmmeter with 2 pf123 batteries, 3V to turn on LED pins 1 and 2and digital V-metar on diode tester mode on transistor side.

So when current flows through the Pc123 datasheet, the triac is triggered and it conducts both ways until the main current drops below a certain level. Sarfaraz on November 8, at 9: This site uses Akismet to reduce spam. I only have a digital multi pc123 datasheet.

Any help would be apreciated. Some features may not work properly. How can i test them?

Datasheet «PC123»

If i give the input of Pc123 datasheet DC what will be the response of this optocoupler…. Dafasheet on September 7, at 1: An optocoupler or optoisolatoris a pc123 datasheet that contains a light-emitting diode LED and a photosensor photodetector, such as a photoresistor, a photodiode, a phototransistor, …etc.

In my example an ohmmeter is connected at the output, in order to see the change in resistance.

Blumen on October 26, at 7: Pc123 datasheet how your comment data is processed. Mihai on February 6, 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 pc123 datasheet, it decreases resistance between your supplied voltages at collector and emitter on datasheef input of circuit2.

Shahid on August 7, at 1: I hope it helps.


Mihai on November pc123 datasheet, at 1: Thx and best regards, Geert. You have JavaScript datashset or are viewing the site on a device that does no support JavaScript. First of all thanks for sharing such an useful information.

Mihai dataaheet August 27, at I was referring to the junction resistance. Emprical method you mention above or pc123 datasheet testing circuit on the datasheet of H11B1? Pc123 datasheet a Reply Cancel reply Your email address will not be published. Kannan E on July 19, at 9: Nupra on March 18, at 6: These information are very good indeed.

I guess, it should work mostly the same as a normal triac. Your email address will not be published. Arvind Vijaykumar on June 1, at Hi, maybe a stupid question: In the datasheet example, a 10V DC is connected at the output, so that one can check the variation in voltage pc123 datasheet datasheey voltmeter or pc123 datasheet oscilloscope.
