What is Zener vs Avalanche Breakdown Explained about?

There are two types of reverse breakdown in diodes: Zener breakdown and avalanche breakdown. Zener breakdown occurs in heavily doped diodes and results from quantum mechanical tunneling. Avalanche breakdown occurs in lightly doped diodes and results from impact ionization causing an avalanche effect. The key differences are that Zener breakdown has a negative temperature coefficient while avalanche breakdown has a positive temperature coefficient. Neither type of breakdown damages the diode crystal lattice,
