I appriciate… I tried that emprical method for H11B1 optocoupler. Transistor Output – Bipolar, Cosmo Electronics. These information are very good indeed. Mihai on February 2, at 5: HTML is not translated! Sign in with Login with Facebook. Got one to sell?

Images shown is only for representation. Single, Dual and Quad format transistor output optocouplers from Lite-On. Sarfaraz on November 8, at 9: Show only see all. Delivery options see all.


Mihai on July 15, at 8: The actual product may vary with the picture shown. Did you reffer to isolation resistance when you mention ;hotocoupler phototransistors have high resistance? Current Transfer Ratio Typ: 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.

Here at Keatronics we have many years experience in the electronics industry. Ado on November 14, at Michael on January 21, at 3: Good design is as little design as possible. Your support will keep us moving forward forever.

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. 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.

It uses the PC optoisolator. Item location see all.


Mihai on July 16, at 5: Better check the datasheet for a test circuit. You have JavaScript disabled or are viewing the site on a photovoupler that does no support JavaScript.

Both single and dual through-hole devices are available as well as a single-channel SMT version. You helped me understand how to use a tester on a optocoupler Thanks. Forward Current If AV: 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.


Hi, The MOC, is a phofocoupler coupler, meaning that instead of the phototransistor, it has photocouplrr phototriac, which is basically a triac with the gate driven by the LED.

Add to Wish List Compare this Product. The EL Phototransistor Photocoupler series of devices each consist of an infrared emitting diodes, optically coupled to a phototransistor detector.

Please provide a valid price range. In my example an ohmmeter is connected at the output, in order to see the change in resistance.

All Auction Buy it now. If i give the input of V DC what will be the response of this optocoupler…. I like the way you explain things. Thx and best regards, Geert. Mihai on March 6, at 2:
