SEMICONDUCTORS

SEMICONDUCTORS. Zener diodes. SEMICONDUCTORS. Ordinary PN junction diodes can be damaged if they are subjected to their respective breakdown voltages. The reverse current produces more heat than the diodes can safely dissipate. Zener diodes are different in this regard. SEMICONDUCTORS.
