WebA Zener diode can use any of these two breakdown mechanisms. Although there are two types of breakdown mechanism, still only name Zener is preferred. Silicon and Germanium both can be used for the construction of Zener diode, but Silicon is often used because of it can operate at higher temperature, and current capability of silicon is high. WebThe breakdown diode is a two-terminal electrical component which is anode as well as the cathode. The diode allows the current flow in only one direction and blocks in the opposite direction. An electrical breakdown takes place due to two types of occurrences like Zener as well as an avalanche. snip the tip reviews
