One of the basic parts of all electronics you’d find, diodes play a role in directing the direction of current through circuits. They act as one way (unidirectional) valves of electrical current, allowing electrical current in one direction only and the sensitive component from reverse voltage damage. There are many types of diodes such as Zener, light emitting (LED), and Schottky diode types which perform special functions. However, due to their contribution to energy efficiency, voltage regulation, and signal modulation, it is important to understand their properties in order to apply them in an effective circuit design.

Diodes are indispensible throughout modern day technology, from personal devices to industrial systems. For example, LEDs are actually diodes that light up with current. On the other hand, Zener diodes have the role of maintaining the voltage levels at a constant level in order to enable stable power to the electronic devices. When both novices and advanced electronic enthusiasts want to optimise their circuits or to widen the knowledge on how components will interact, familiarity with the different types and apps of diodes is crucial.
