How To Calculate Optocoupler Resistor at Samantha Atherton blog

How To Calculate Optocoupler Resistor. R2 is the load resistor for the. If i understood the optocoupler concepts correctly, i need about 10ma at 5v to get 100% ctr: Also, what current is required to operate the reed relay? In choosing appropriate values for r1, the value for the current limiting resistor is set to produce the correct forward current (i f) through the infrared led in the optocoupler. For the led is 1.6v: The worse case of forward v. According to the data sheet with if=1ma minimum ctr is 34%. The gain of the optocoupler is expressed as a current transfer ratio (ctr), which is the collector current (ic) of the output divided by the forward. Given the voltage drop of the led at 1.2 v, for 5 v, then 4v divided by 5 ma is 800 ohms, a common value is 820 ohms (and there is no. Divide it to ctr and the result is your needed input current. You have to know load current (output current). After defining rf and the forward current, you can determine the value of rc. So the resistor math would be:
