breakdown voltage (uncountable)
The minimum voltage that causes part of an insulator to become electrically conductive.
Examples
; Avalanche diodes :These are diodes that conduct in the reverse direction when the reverse bias voltage exceeds the breakdown voltage.
Depending on the breakdown voltage of the spark gap, it may fire many times during a mains AC cycle.
Like a typical diode, there is a fixed anode and cathode in a Zener diode, but it will conduct current in the reverse direction (electrons flow from anode to cathode) if its breakdown voltage or "Zener voltage" is exceeded.
In a solid, the breakdown voltage is proportional to the band gap energy.
There is always some voltage (called the breakdown voltage ) that gives electrons enough energy to be excited into this band.
The reverse bias breakdown voltage to the base may be an order of magnitude lower in this region.
