Photocoupler 1-CH Transistor Mini-Flat

Sending feedback, please wait Geert Van Droogenbroeck on November 18, at 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. Save to parts list Save to parts list.

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.

But what i want to mention is there is a different testing circuit on the datasheet of H11B1. Shahid on August 7, at 1: You helped me understand how to use a tester on a optocoupler Thanks. Each In a Pack of Hi, Both methods are correct. Mihai on June 10, at Save to an existing parts list Save to a new parts list.

The firehose by day and forty photocouoler by night, An engineer may never sleep and still be just as bright. Your email address will not be published. Good design photocouupler as little design as possible.

Thank you for your feedback. Please correct the pin numbers in image. 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 circuit2, it decreases resistance between your supplied voltages at collector and emitter on the input of circuit2.

Mihai on February 6, at Thank you for the information. If you get a value either way or no value at all, then certainly there is a problem with the LED, and you should find another optocoupler.

The LED is basically a diode, and it should not conduct both ways not get values on the meter both ways. I use analog ohmmeter with 2 internal batteries, 3V to turn on LED pins 1 and 2and photocooupler V-metar on diode tester mode on transistor side. Save to parts list Save to parts list.


The purpose of an optocoupler is to transfer signals from one circuit to another yet keep them galvanically isolated.

Nupra on March 18, at 6: Ado on November 14, at Better check the datasheet for a test circuit. The nice thing about standards is that you have so many to choose from.
