Muhammad Akhlaq on May 30, at 9: 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.

A photocoupler, or optical isolator or an opto – isolator is a component that transfers electrical signals between two isolated circuits by using light. It transforms useful input signal into light, sends it across the dielectric channel, captures light on the output side and transforms it back into electric signal.

Here is the web site. There is no law governing all things. Delivery options see all. The question is which one is the right testing method?

Compact small outline package. Thanks for the easy to follow explanation of how to rest an optocoupler.

If i give the input of V DC what will be the response of this optocoupler…. Mihai on July 19, at 3: Mihai on February 6, at Signal transmission between circuits of different potentials and impedances. The optocoupler is FL Phptocoupler F, should i just join the emittor and collector pins?

I was referring to the junction resistance. Hi, Both methods are correct. Some features may not work properly. Thank you for the information… and i have one photockupler clarifications.

Mihai on February 2, at 5: Hi, maybe a stupid question: Emprical method you mention above or the testing circuit on the datasheet of H11B1?

If the input is at 2V DC, then the output resistance should be around — ohms. I like the way you explain things. Skip to main content.
