reverse voltage applied
Yes diode is useful after break down because it flows current from one direction to other direction
because of its high break down voltage.
A Germanium diode has a much lower breakdown voltage than a silicone diode.
Peak reverse voltage of a diode is the maximum reverse bias voltage can be applied to diode which does not cause break down.
In a reverse bias higher than the break down voltage.
The effect is quite simple, to be honest. When putting a leaked diode in a circuit, it will cause the other ones to break down.
The breakdown voltage point for a Zener diode is 17 volts
A: Yes it does since the break down is not exactly very linear.
the energy required to break covalent bond in si is 1.1ev and in ge is 0.7ev
Since they are in parallel, the 3.3V zener diode will "kick in" first when you reach 3.3V, and the circuit will pretty much act the same as if the 7V zener diode isn't there at all.
A Thyrector is essentially two zener diodes connected back-to-back in opposing polarity which means it will not conduct until an over-voltage above its break-down voltage rating occurs. This is used to trap voltage spikes and suppress them.
When light falls on the junction of a pn junction/diode the potential barrier gets break down due to majorty of electrons flow and they release energy in the form of light.
