The main idea is to create the diode using high doped n + and p + regions, thereby ensuring the low triggering voltage. Jun 19, 2016 · Zener diodes are a special type of semiconductor diode– devices that allow current to flow in one direction only –that also allow current to flow in the opposite direction, but only when exposed to enough voltage. 7 volts. Developed By While for practical purposes, the Zener diode breaks down at its rated voltage and allows current through at any voltage over that, the reality is a little different. Log In Sign Up. It is a specific diode that works in reverse bias conditions. The following figures show the schematic symbols of a zener diode. When forward-biased, 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. The previous experience has made us understand that if a Zener diode inversely polarized goes to conduction, there is a fixed voltage, Vz, on it. For example, if there is always a voltage of 12 V on a 12-V Zener, regardless of the supply voltage, then the Zener can be used as a voltage stabilizer.
