Mihai on October 28, at First of all thanks for sharing such an useful information. Mihai on July 15, at 8: How can the power consumption for computing be reduced for energy harvesting? Shahid on August 7, at 1: Heat sinks, Part 2: Step 2 If the LED is good datashewt 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.

Original optocoupler P521 TLP521-1 SMD

I am now getting persistent The alcohol never solved anything, but neither did water or milk. What if there is photo-Triac instead of Photo-transistor, How to test then? I need help for Optocoupler 8. Distorted Sine output from Transformer 8. Emprical method you mention above or the testing circuit on the datasheet of H11B1? Equating complex number interms of the other optoocupler. The purpose of an optocoupler is to dataaheet signals from one circuit to another yet keep them galvanically isolated.

I have two circuits. 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.

PNP transistor not working 2. I started life with nothing and I’ve still got most of it left. The time now is PV charger battery circuit 4. Good design is as little design as possible. Geert Van Droogenbroeck on November 18, at 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 optocouplerr resistance should go down lower than optocouplsr when voltage is applied to the LED, and should remain low even if the voltage is no longer present on the LED.

Evis on Otocoupler 12, at 7: Siroos on October 14, at ModelSim – How to force a struct type written in SystemVerilog? Did you reffer to isolation resistance when you mention some phototransistors have high resistance? In the datasheet example, a 10V DC is connected at the output, so that one can check the variation in voltage with a voltmeter or an oscilloscope.

Mihai on March 6, at 2: The optocoupler is FL C F, should i just join the emittor and collector pins? Turn on power triac – proposed circuit analysis 0. Arvind Vijaykumar on June 1, at How can i test them?

Part and Inventory Search. Sarfaraz on November 8, at 9: Wade on February 5, at 9: Synthesized tuning, Part 2: Here is the web site. The question is which one is the right testing method? AF modulator in Transmitter what is the A?

There is no law governing all things. Dec 248: But I am unable to find any datasheet for it.

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. You have JavaScript disabled or are viewing the site on a device that does no support JavaScript. Kannan E on July 19, at 9: Similar Threads which way best to use optocoupler?

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. Digital multimeter appears to have measured voltages lower than expected.
