20 x Zener Diode BZX55 500mW (0.5W) Various Voltages


SKU: N/A Category:


Zener Diode is a circuit component that only enables current to flow in one direction. Diodes come in different sizes, and they typically have a black cylindrical body with two leads coming to the sides (Anode and Cathode) and a stripe at the Cathode end. Diodes are like one-way streets. The current can only move from the Cathode end to the Anode end through the diode. This occurs because the diode prevents current from flowing in the opposite direction from the Anode side. A diode is reverse biased when it acts as an insulator and forward biased when it allows current flow. A diode’s anode and cathode are its two terminals. Diodes are used in circuits to limit voltage and convert AC to DC. Semiconductors like silicon and germanium are employed to get the most out of diodes. Even though they both transfer power in the same direction, the way they do so is different. Diodes come in various shapes and sizes, each with its own set of applications, such as Zener diodes. Switches, signal modulators, signal mixers, rectifiers, signal limiters, voltage regulators, etc., are all examples of diode applications.
