semiconductors 1 E. COATES 2016 Semiconductor Diodes Module Diodes Introduction Diodes are one of the simplest, but most useful of all Semiconductor devices. Many types of diode are used for a wide range of applications. Rectifier Diodes are a vital component in power supplies where they are used to convert AC mains (line) voltage to DC. Zener Diodes are used for voltage stabilisation, preventing unwanted variations in DC supplies within a circuit, and to supply accurate reference voltages for many circuits.
red: Yellow and green indicator LEDs, an infra red photodiode, a 5mm warm white LED and a 10mm high luminosity blue LED. Diode Circuit Symbols A diode is a one-way conductor. It has two terminals, the anode or positive terminal and the cathode or negative terminal.
