A diode is an electronic component that allows current to flow only in one direction between its two connectors. Semiconductors diodes are the most popular type of diodes. There are multiple types of diodes to consider when selecting a diode for your application such as; Bridge Rectifier Diodes, Current Regulator Diodes, Microwave Mixer Diodes, Microwave Special Purpose Diodes, PIN Diodes, Rectifier Diodes, as well as, Other Diodes. Other classifications for diodes include Light-emitting diodes (LED), Photodiodes, Schottky diodes, Transient-voltage-suppression diodes (TVS), Tunnel diodes, Varicaps, and Zener diodes.
