Basis For Comparison	PN Junction Diode	Zener Diode
Definition	It is a semiconductor diode which conducts only in one direction, i.e., in forward direction.	The diode which allows the current to flow in both the direction i.e., forward and reverse, such type of diode is known as the Zener diode.
Symbol	<a href="https://circuitglobe.com/wp-content/uploads/2017/05/diode-symbol.jpg"></a>	<a href="https://circuitglobe.com/wp-content/uploads/2017/05/zener-diode.jpg"></a>
Reverse Current Effect	Damage the junction.	Do not damage the junction.
Doping Level	Low	High
Breakdown	Occurs in higher voltage.	Occur in lower voltage.
Ohms Law	Obey	Do not obey.
Applications	For rectification	Voltage stabilizer, motor protection and wave shaping.
