If the Optocouple 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.

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 p512, it decreases resistance between your supplied voltages at collector and emitter on the input of circuit2.

But I am unable to find any datasheet for it.

The firehose datasheeh day and forty beers by night, An engineer may never sleep and still be just as bright. You helped me understand how to use a tester on a optocoupler Thanks. How to set up an optocoupler to use it in the output of flyback converter?

I have connected to the Ring Red wire to the pin 1 of optocoupler tough a capacitor and a resistor in serial and have connected Tip Green wire to the pin 2 through a 1N diode.

The alcohol never solved anything, but neither did water or milk. Losses in inductor of a boost converter 9.

I guess, it should work mostly the same as a normal triac. Your email address will not be published. Sunil on March 3, at 3: Thank you for the information.

Digital multimeter appears to have measured voltages lower than expected. Arvind Vijaykumar on June 1, at Dec 248: But I am unable to find it.

Original optocoupler P521 TLP521-1 SMD

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. Wade on February 5, at 9: You have JavaScript disabled or are viewing the site on a device that does no support JavaScript.


The nice thing about standards is that you have so many to choose from.

Turn on power triac – proposed circuit analysis 0. Mihai on March 18, at Looking for the pinout of P Optocoupler. The LED is basically a diode, and it should not conduct both ways not get values datasehet the meter both ways.

Good design is as little design as possible. 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.

Equating complex number interms of the other 6.
