Opto Coupler Zener Diode at Sheryl Butler blog

Opto Coupler Zener Diode. 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. There are special surge supressor diodes for this usage. You might consider using a lower zener (tvs) voltage, say 5v. That will cause less variation of diode current between 12v and 24v input voltage. Optoisolators tend to age poorly, and the ctr will. One cheap way to force a bias current in the zener diode is to wire a resistor in parallel with the led. Since a nano will probably fry instantly if the 12v trigger wire is directly connected to it, i used to use a 5v1 zener. Isolation is needed to handle ground potential differences and to protect against high voltage. The traditional solution for ac detection is to. To regulate the voltage ofone. Your dealer should be able to help to find the right. As the led drop is around 1 v, then the injected current is \$\approx.
