Photocoupler 1-CH Transistor Mini-Flat
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 photocoupoer resistance value both ways if the phototransistor is good.
Ado photocoupelr November 14, at photocouplef If i give the input of V DC what will be the response of this optocoupler…. Each On a Reel of 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 purpose of an optocoupler is to transfer signals from one circuit to another yet keep them galvanically isolated. Allowing you to reduce waste and improve production efficiency.
The firehose by day and forty beers by night, An engineer may never sleep and still be just as bright. Mihai on July 16, at 5: How phltocoupler optocoupler Type SFH acts when the positive line is open. Some features may not work properly. Hi, Both methods are correct. Thank you for the information.
Here is the web site. The product does not contain any of the restricted substances in concentrations and applications banned by the Directive, and for components, the product is capable of being worked on at the higher temperatures required by lead—free soldering.

Mihai on October 28, at So when current flows through the LED, the triac is ;hotocoupler and it conducts both ways until the main current drops below a certain level.

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 this resistance should go down lower than ohms when voltage is applied to the Photlcoupler, and should remain low even if the voltage is no longer present on the LED.
Thank you for your feedback. For response time or frequency photocoipler data, check the datasheet.
