the current should not exceed rated current
zener diodes behave much the same as standard rectifying diodes: they have a forward voltage drop which follows the “diode equation” and is about 0.7 volts. In reverse-bias mode, they do not conduct until the applied voltage reaches or exceeds the so-called zener voltage, at which point the diode is able to conduct substantial current, and in doing so will try to limit the voltage dropped across it to that zener voltage point. So long as the power dissipated by this reverse current does not exceed the diode’s thermal limits, the diode will not be harmed.
apply a capacitor in parallel
The Current should not exceed the Rated Value otherwise the diode will get destroyed
All diodes allow current to pass in one direction only. In normal use, diodes never suffer a reverse breakdown which would destroy the diode. Zener diodes are special because they can break down without being damaged. They do this at a specific voltage (the Zener voltage) which is accurately determined by the manufacturing process.
don't exceed max current, and don't exceed reverse (knee) breakdown voltage
you need to put a series resistor with the zener diode
If you are using it in forward bias condition then it doesn't exceeds breakdown voltage
It depends on your circuit, maybe you can give further information about it.
Most of the times, you need to put a serial resistor with the zener, calculate the maximum current in the resistor and check in the zener data sheet if it is compliant.
To ensure that a zener diode does not get destroyed. ... the applied voltage should not exceed breakdown voltage, False. the current should not exceed rated
