And that is also important. You will have values well inside the spec of the opto. Posted by rjjenkins in forum: The second part of circuits work on 5VDC, because there are some TTL components like shift registers, microcontroller etc. Jan 22, 4. Jan 22, 5.

Use anything from 1Kohm to to 10K. I will use a trimmer instead a resistor.

Optocoupler fails after month. By using a 4.

There is a simple formula to calculate the two resistor for each optocoupler? Assume using figure 2 chy74-2 the datasheet. I do not know were you got the nA from. Jan 20, 1. But the transistor in the opto will be more or less full on with a LED current of 15mA.

CNY74-4 Optocoupler

From the datasheet I think a LED current in range mA should be enough to turn the transistor into saturation. I guess a 4. We see that the Saturation voltage, collector emitter dataaheet be at typical.

This will show the voltage drop versus current. Jan 22, 9. Tales from 80s Tech: And you will no problem at all.

TEMIC – datasheet pdf

No need to have the transistor conducting max current. Quote of the day.

Jan 22, 8. If the opto is connected to some 5 volt logic gate or controller. Hence the emitter resistor will control the current. No, create an account now.

OptoCoupler Posted by mpuvdd in forum: The LED will also have a voltage drop. In summary, hereafter you can see the formulas for resistors wattage: The higher Vce voltage drop. But use a emitter resistor in the range of 4. Go for a LED current equal to 15mA. Find the voltage drop at 15 mA and take this into your calculations please. You have got how to fny74-2 the LED series resistor correct.
