diode symbol meaning
A diode has two terminals. The positive side is called the anode, and the negative one is called the cathode. The diode circuit symbol, with the anode and cathode marked. Current through a diode can only flow from the anode to the cathode, which would explain why itâs important for a diode to be connected in the correct direction. Physically, every diode should have some sort of indication for either the anode or cathode pin.
