$\huge{\boxed{\mathfrak\pink{\fcolorbox{blue}{lawngreen}{Answer \:}}}}$

The Avalanche Breakdown and Zener Breakdown are two different mechanisms by which a PN junction breaks. The Zener and Avalanche breakdown both occur in diode under reverse bias. The avalanche breakdown occurs because of the ionisation of electrons and hole pairs whereas the Zener diode occurs because of heavy doping.
