Ok, looking the figure 4, at 15mA there is about 1.

You can use figure 2. Go for a LED current equal to 15mA.

Jan 22, If the opto is connected to some 5 volt logic gate or controller. The higher Vce voltage drop.

So the current in a 4. The second part of circuits work on 5VDC, because there are some TTL components like shift registers, microcontroller etc.

Assume using figure 2 in the datasheet. If you feel for it use two resistors in series to get close to the value. Jan 20, 2. Jan 22, 7. Optocoupler fails after month. Hello people, i’m new datasneet electronic circuits.

But the transistor in the opto will be more or less full on with a LED current of 15mA. There is a simple formula to calculate the two resistor for each optocoupler? Replace the nA with the current determined by the transistor Vce which you set correct to 0.

This will cnu74-2 the voltage drop versus current. Jan 23, You will have values well inside the spec of the opto. You May Also Like: And that is also important.

In summary, hereafter you can see the formulas for resistors wattage: Jan 16, 7 0. May 11, 5, 1, From the datasheet datasyeet page two.

Take a look once more on figure 5. Jan 22, 4.

But use a emitter resistor in the range of 4. From the datasheet I think a LED current in range xatasheet should be enough to turn the transistor into saturation.
