Optocoupler Resistor Calculation at Dustin Padilla blog

Optocoupler Resistor Calculation. I have used the calculator available here: Using series resistor of 1.5k at 3.3v. The resistance to let 400 ua through at an instantaneous mains voltage level vm down to,. Can someone recommend a resistor value, thank you very much. Equations 1 and 2 calculate the required current range through the optocoupler photo detector, assuming that you use a 1kω resistor with a 1%. In the optocoupler, or photon coupled pair, the coupling is achieved by light being generated on one side of a transparent insulating. 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. According to the data sheet with if=1ma minimum ctr is 34%. R2 is the load resistor for the.
