WEBMay 24, 2019 · Although standard diodes and Zener diodes can both be used for transient protection, they are actually designed for rectification and voltage regulation, and, therefore, are not as reliable or robust as transient voltage suppressor diodes. Transient Voltage Suppressor (TVS) Diode Symbols: Unidirectional (left) and bidirectional (right).
