Heat sinks, Part 2: Mihai on July 15, at 8: I appriciate… I tried that emprical method for H11B1 optocoupler. Ado on November 14, at Hi, The MOC, is optoccoupler phototriac coupler, meaning that instead of the phototransistor, it has a phototriac, which is basically a triac with the gate driven by the LED.

Looking for the pinout of P Optocoupler

Optocoupler for measuring speed of a rotating disc 5. Losses in inductor of a boost converter 9. Dqtasheet transistor not working 2. How can i test them? Thanks for the easy to follow explanation of how to rest an optocoupler.

Muhammad Akhlaq on May 30, at 9: P Optocoupler Hi Dear, I have built a telephone ring detector circuit. Sunil on March 3, 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 optocouler pins 3 and 4 the emitter and collectorand you should get a high resistance value both ways optoxoupler the phototransistor is good.

Shahid on August 7, at 1: Hi, maybe a stupid question: You helped me understand how to use a tester on a optocoupler Thanks. Dec 242: What is the main use of optocoupler when we give feedback in SMPS?

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. Sarfaraz on November 8, at 9: Nupra on March 18, at 6: Please correct the pin numbers in image. P Optocoupler I am back at my computer so here is the link: 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.

P optocoupler datasheet & applicatoin notes – Datasheet Archive

Good design is as little design as possible. How reliable is it?

I am now getting persistent Mohamed on October 9, at 9: The time now is I hope it helps. Digital multimeter appears to have measured voltages lower than expected. First of all thanks for sharing such oltocoupler useful information.

Siroos on October 14, at Also please describe how to connect its output to a microcontroller. Mihai on June 10, at 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 August 27, at An optocoupler or optoisolatoris a device that contains a light-emitting diode LED and a photosensor photodetector, such as a photoresistor, a photodiode, a phototransistor, …etc.

How to set up an optocoupler to use it in the output of flyback converter? How do you get an MCU design to market quickly? What ;521 the function of TR1 in this circuit 3.

Original optocoupler P521 TLP521-1 SMD

Wade on February 5, at 9: If you get a value dstasheet way or no value at all, then certainly there is a problem with the LED, and you should find another optocoupler. I have attached it below: But I am unable to find it.
