electronic components kp1010 817b
Mihai on March 18, at You helped me understand how to use a tester on a optocoupler Thanks. 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.
Nupra on March 18, at 6: Here is the web site. High accuracy and high sensitivity enable the dedication in automotive applications as well as consumer products. For response time or frequency response data, check the datasheet. Sanu sebastian on August 19, at I only have a digital multi meter.
kp optocoupler datasheet & applicatoin notes – Datasheet Archive
The LED is basically a diode, and it should not conduct both ways not get values on the meter both ways. I hope it helps.
Ado on November 14, at But what i want to mention is there is a different testing circuit on the datasheet of H11B1. If the input is at 2V DC, then the output resistance should be around — ohms.
The purpose of an optocoupler is to transfer signals from one circuit to another yet keep them galvanically isolated. Absolute Pressure Sensor IC. Better check the datasheet for a test circuit.
Blumen on October 26, at 7: Wade on February 5, at 9: I like the way you explain things. Hi, maybe a stupid question: Your email address will not be published. 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. Infineon Technologies Electronic Components Datasheet.
If the LED is good datasneet we should check the phototransistor, you could measure xatasheet 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. High accuracy and high sensitivity enable the. Mihai on March 6, at 2: The firehose by day and forty beers by night, An engineer may never sleep and still be just as bright.

I was referring to the junction resistance. Hi, The MOC, is a phototriac coupler, meaning that instead of the phototransistor, it has a phototriac, which is basically a datasneet with the gate driven by the LED. Sarfaraz on November 8, at 9: Emprical method you mention above or the testing circuit on the datasheet of H11B1? Mihai on June 10, at It is surface micromachined with a monolithic integrated signal conditioning.
Shahid on August 7, at 1: This site uses Akismet to reduce spam. In my example an dwtasheet is connected at the output, in order to see the change in resistance. Muhammad Akhlaq on May 30, at 9: How can i test them?
What if there is photo-Triac instead of Photo-transistor, How to test then? The optocoupler is FL C F, should i just join the emittor and collector pins?
