A diode is a semiconductor device consisting of two electrodes, namely the anode and the cathode. Its primary function is to allow the flow of current in one direction while impeding the current in the reverse direction. This non-linear electrical characteristic enables diodes to serve various roles in electronic circuits, such as rectification, light emission, logic gates, circuit protection, and more.
