Optocoupler Zener Diode at Julie Scot blog

Optocoupler Zener Diode. The traditional solution for ac detection is to. A resistor in parallel to the optocoupler is like a current generator for the zener diode, forcing the circulation of appropriate current in addition to the small led one. Isolation is needed to handle ground potential differences and to protect against high voltage. You can get away with a regular zener diode instead of a tvs. Concentrate on feedback that uses an optocoupler. Since a nano will probably fry instantly if the 12v trigger wire is directly connected to it, i used to use a 5v1 zener. You might consider using a lower zener (tvs) voltage, say 5v. That will cause less variation of diode current between 12v and 24v. A zener would compound this problem, rather than solving it. There are two common techniques to generate a secondary reference with optocoupler. To regulate the voltage ofone. A high impedance drive circuit. Be an indication of a more fundamental problem:
