1N4007 Rectifier Diode

Polarity and Pinout

The 1N4007 diode has two terminals: a cathode (–) and an anode (+). In the schematic symbol, the tip of the triangle with the line on top of it represents the cathode. On the actual body of the 1N4007, the cathode is marked with a band, making it easy to identify during circuit assembly.

1N4007 Diode Polarity

The 1N4007 diode allows current to flow only in one direction—from the anode to the cathode—and blocks reverse flow. This behavior makes the 1N4007 diode act like a one-way valve in electronic circuits. Due to this property, it is commonly used in rectifier diode bridge circuits for converting AC to DC.
