Mihai on July 19, at 3: Kannan E on July 19, at 9: Hi, First of all thanks for sharing such an useful information. I am now getting persistent Did you reffer to isolation resistance when you mention some phototransistors have high resistance?

Original optocoupler P521 TLP521-1 SMD

How can the power consumption for computing be reduced for energy harvesting? 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.

Evis on November 12, at 7: The LED is basically a optocouplr, and it should not conduct both ways not get values on the meter both ways. Hierarchical block is unconnected 3.

Better check the datasheet for a test circuit. Sunil on March 3, at 3: Distorted Sine output from Transformer 8. Input port and input output port declaration in top module 2.

P Optocoupler i hope ur able to find out pin 1 in that device. So when current flows through the LED, the triac is triggered and it conducts both ways until optociupler main current drops below a certain level.

Shahid on August 7, at 1: Mihai on July 15, at 8: I have two circuits. P Optocoupler I seem to be unable to post a link at the moment, but google Toshiba TLP – it should get you the p251 sheet.

Choosing IC with EN signal 2.

Thank you for the information. Dec 242: I have attached the element’s image.

Sanu sebastian on August 19, datasheeet The nice thing about standards is that you have so many to choose from. Hi, Both methods are correct. Any helpful idea will get rewards in paradise.

P optocoupler datasheet & applicatoin notes – Datasheet Archive

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. P Optocoupler u can try this ring detector circuit Mihai on November 20, at 1: Viliam on September 7, at 1: But I am unable to find it.

Ado on November 14, at I need help for Optocoupler 8. Geert Van Droogenbroeck on November 18, at
