Working Principle

CDBA5819-HF uses the process of rectification, which is the conversion of alternating current (AC) to direct current (DC) and is the most common type of power conversion used in most electronic circuits. The CDBA5819-HF diode functions as a unidirectional valve that will only allow current to flow in one direction. The CDBA5819-HF diode has a built-in anode and cathode which can be easily identified due to its forward bias. When the CDBA5819-HF forward biased, it will allow the current to flow from anode to cathode. During the forward biased process, the charge carriers (electron and hole) recombine and this recombination process will convert the AC power to DC power. In addition to this, the purpose of the CDBA5819-HF diode is to prevent current from flowing in the opposite direction, known as reverse bias operation. This reverse bias function will protect the electronic circuit from unwanted electricity or static electricity.
