Diodes A broad family of semiconductor devices that allow current to flow in one direction and block it in the opposite direction. They are used to control, convert, and protect electrical signals in a wide range of products. Key benefits Protect circuits from reverse polarity and voltage spikes, helping extend component life Enable efficient rectification to convert AC to DC in power supplies Provide fast switching for timing and speed digital circuits Offer voltage regulation and clamping with Zener and transient suppression diodes Available in multiple materials and speeds to suit different designs Flexible form factors with through hole and surface mount packaging Function and performance Forward conduction characteristics vary by type; silicon diodes provide standard conduction, Schottky diodes deliver lower forward voltage drop for higher efficiency Reverse voltage ratings range from low to to meet different design requirements Switching speeds range from standard to ultrafast for timing, protection, and signal integrity Surge and peak current handling is available across a range of diodes to absorb transient events Compatibility and forms Works with common PCB footprints and assembly processes Available in silicon, Schottky, fast recovery, and Zener diode variants Multiple package styles and mounting options to fit board density and thermal design Materials and size Diodes are built from silicon or other semiconductor materials depending on type and rating Available in compact surface mount packages and through hole styles to fit various product dimensions Use scenarios Power supply rectification in consumer electronics, LED drivers, and charging circuits Reverse polarity protection in automotive, industrial, and portable devices Voltage regulation and clamping using Zener diodes or transient suppression diodes
