A diode is an essential component in electronics that allow current to flow in only one direction. They are commonly used for rectification (changing AC to DC), voltage regulation, and protection in circuits. This quick reference covers diode symbols, polarity, and two common types: the 1N4148 (signal diode) and 1N4007 (rectifier diode). Common Diodes for … Continue reading Diode Quick Reference for Beginners in Electronics
