WebDec 11, 2024 · At high reverse bias, the exact mechanism that creates breakdown and drives current flow is different in various diodes (pn diode, Schottkey, or Zener). When looking at the equation describing current in a diode, only the forward current is considered; the reverse current resulting from breakdown in the diode is not present in this equation. WebA Zener diode is a special type of diode designed to reliably allow current to flow "backwards" (inverted polarity) when a certain set reverse voltage, known as the Zener voltage, is reached. Zener diodes are manufactured …
