Wade on February 5, at 9: The optocoupler is FL C F, should i just join the emittor and collector pins? Emprical method you mention above or the testing circuit on the datasheet of H11B1?

TOSHIBA – datasheet pdf

I have attached the element’s image. Michael on January 21, at 3: The firehose by day and forty beers by night, An engineer may never sleep and still be just as bright.

Evis on November 12, at 7: Choosing IC with EN signal 2. Good design is as little design as possible.

How do you get an MCU design to market quickly? Hi, maybe a stupid question: Turn on power triac – proposed circuit analysis 0.

I appriciate… I tried that emprical method for H11B1 optocoupler.

Original optocoupler P521 TLP521-1 SMD

If the input is p512 2V DC, then the output resistance should be around — ohms. First of all thanks for sharing such an useful information. This site uses Akismet to reduce spam. 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 dtasheet be high open circuit or at least dataseet than 1 megohm both ways, and this resistance should go down lower than ohms when voltage is applied to the LED, and should remain low even if the voltage is no longer present on the LED.

Any help would be apreciated. Nupra on March 18, at 6: These information are very good indeed. 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.

Arvind Vijaykumar on June 1, at The question is which one is the right testing method? How can i test them?

Please correct the pin numbers in image. How reliable is it?

The alcohol never solved anything, but neither did water or milk. Thx and best regards, Geert. I have optocopuler it below: P Optocoupler is not necessary. Hi, Both methods are correct. Distorted Sine output from Transformer 8. PV charger battery circuit 4. Heat sinks, Part 2: I was wondering if i could just bypass the optcoupler and see if it works. What is the main use of optocoupler 5p21 we give feedback in SMPS?

Optocoupler for measuring speed of a rotating disc 5. Shahid on August 7, at 1: I was referring to the junction resistance.

Better check the datasheet for a test circuit. I started life with nothing and I’ve still got most of it left. P Optocoupler I datashedt back at my computer so here is the link: What is the function of TR1 in this circuit 3. Similar Threads which way best to use optocoupler?
