5 Selecting the Correct Protection Diode

As mentioned in past sections, there are various types of diodes that include Junction, Schottky, Zener and others. For the purposes of this application note, this document focuses on the following protection diode categories designed to protect against excessive voltage and current – zener diode, electrostatic discharge (ESD) diode, and transient voltage suppression (TVS) diode, how to properly select the right diode for an application.
