# MDD72-18N1B application field and working principleThe MDD72-18N1B is a type of diode rectifier array, which consists of three separate sections. The first section is made up of two separate diodes, also referred to as a "half-wave rectifier" configuration. This configuration allows for positive voltage to flow in one direction while blocking negative voltage from flowing in the opposite direction. The second section is made up of four diodes which make up the bridge rectifier configuration. This configuration allows for a full-wave rectification of voltage, allowing both positive and negative voltages to flow in each direction, thus increasing the efficiency of the power conversion. The third section is made up of eighteen individual diodes which offer reverse current protection for the circuit.The MDD72-18N1B can be used in a variety of different applications, including automotive, consumer, industrial, and medical electronics. Its most common application is as a rectifier in power supplies, where it is often used to convert alternating current (AC) into direct current (DC). Other applications include DC-AC and AC-DC conversions, power switching, and signal processing. The MDD72-18N1B is particularly suited to replacing 78Mxx series diodes, MOSFETs, and relay contacts.The MDD72-18N1B\'s working principle is based on the physics of the P-N junction diode. A P-N junction diode is a two-terminal semiconductor device which allows current to flow in one direction only. When a voltage is applied to the diode such that its anode is more positive than its cathode, it will become forward-biased, allowing current to flow. The diode will only allow current to flow in one direction (from anode to cathode in this case), and block any current flowing in the other direction, making it an ideal candidate for rectifying AC voltage into DC voltage.The MDD72-18N1B offers several benefits such as: low forward voltage drop; low power loss; low leakage current; reverse voltage protection; zero voltage switching; and fast switching speeds. It also has a wide operating temperature range and is RoHS compliant, making it an ideal choice for a variety of applications.The MDD72-18N1B can be used in a wide range of applications, from automotive to consumer electronics, but is best suited for applications requiring efficient power conversion or signal restoration. It has a wide operating temperature range, low power loss, reverse voltage protection, and fast switching speeds, making it an ideal choice for a variety of power conversion and signal processing tasks.
