1N4007 Rectifier Diode

The 1N4007 Diode is one of the most popular and reliable general-purpose rectifier diodes used in electronics. It’s designed to handle high reverse voltage and moderate forward current, making it ideal for AC to DC conversion, power supply rectification, and reverse polarity protection in a wide range of electronic circuits. Due to its robust construction and affordability, the 1N4007 is widely used by engineers, students, and hobbyists in power electronics, chargers, adapters, and embedded systems.

1N4007 Diode Polarity and Pinout

The 1N4007 diode has two terminals: an anode (+) and a cathode (–). The cathode is marked with a silver or white band on the diode body for easy identification. Current flows only in one direction—from the anode to the cathode—allowing the diode to act as a one-way valve for electrical current. This property makes the 1N4007 diode ideal for rectifier bridge circuits, where four diodes are connected to convert AC (alternating current) into DC (direct current). Correct polarity ensures proper circuit operation and prevents damage to electronic components.
