WebMar 17, 2024 · Zener impedance should ideally be zero, but in reality, a Zener diode has some impedance. What is dynamic resistance of Zener diode at zener voltage? Dynamic resistance can be as low as a couple of ohms at that current, with zener voltages around 5 – 6V giving the best result. Note that this coincides with the best thermal performance as well. WebKey Takeaways. An impedance mismatch in a circuit or along a transmission line will produce a reflection back to the source of the signal. When a signal reflects, the power transferred downstream towards a load is reduced. Impedance matching provides a dual role of enabling power transfer into a load by suppressing reflections. time warner magazines
