Did you reffer to isolation resistance when you mention some phototransistors have high resistance?

This site uses Akismet to reduce spam. Hi, Both methods are correct. The alcohol never solved anything, but neither did water or milk. The foregoing information relates to product sold on, or after, the date shown below. Pls let me know. 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.

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 LED, and should remain low even if the voltage is no longer present on the LED.


I hope it helps. Thx and best regards, Geert.

How to test an optocoupler – AntiMath

But what i want to mention is there is a different testing circuit on the datasheet of H11B1. You helped me understand how to use a tester on a optocoupler Thanks. Ado on November 14, at Kannan E on July 19, at 9: What if there is photo-Triac instead of Photo-transistor, How to test then?

Mihai on February 2, at 5: If i give the input of V DC what will be the response of this optocoupler…. RoHS Certificate of Compliance. The Manufacturers and RS reserve the right to change this Information at any time without notice.

The LED is basically a diode, and it should not conduct both ways not get values on the meter photocouplet ways. Mihai on September 17, at I have two circuits.

Thank you for the information. Siroos on October 14, at RoHS Certificate of Compliance. Mihai on November phptocoupler, at 1: Hi, maybe a stupid question: How the optocoupler Type SFH acts when the positive line is open. Mihai on March 18, at Here is the web site.
