MD70K16D1-BP is a type of diode rectifier array. Diodes are used for the purpose of rectification, the process of converting alternating current (AC) to direct current (DC) and to provide a non-conductive path for current passing in one direction only.

Application

MD70K16D1-BP is specifically designed for high frequency and high current rectification applications in telecom power systems. This type of rectifier is smaller in size and suitable for high frequency boost or buck regulators, or can be used in 2 and 3 stages of forward converters. It is a good choice for telecommunication applications and is widely used in LNB (Low Noise Block) converters and satellite TV receivers.

Working Principle

The MD70K16D1-BP consists of 16 rectifying diodes connected in parallel. The diodes are in an array of 8 pairs of diodes that are connected in series. Each pair of diodes has different polarity and is used to convert incoming AC power to DC. Due to the parallel connection, the forward voltage drop of each diode is reduced resulting in a lower forward voltage drop across the entire package.

In the event of a high voltage input, the diodes will form a path for the current to flow through and rectify the incoming power. Each pair of diodes within the package is in a reversed voltage polarity, therefore, during the positive cycle of the AC power, one diode will open and allow the current to pass while the opposing diode within the pair will close and block the current flow. During the negative cycle of the AC power, the previously closed diode within the pair will open and allow the current to pass, while the opposing diode will close and block the current flow.

In this manner, the diodes within the package act as a bridge rectifier and allow for rectified current through the device and simultaneously prevent loss of energy due to the current flowing back into the source. This type of rectifier requires fewer components, making it a good choice for high frequency applications.

The MD70K16D1-BP has a maximum forward bias surge current rating of 20A and a maximum reverse breakdown voltage of 500V. It also has a thermal resistance of 121°C/W, allowing it to handle a large amount of heat and current without being damaged.

In conclusion, MD70K16D1-BP is a popular rectifier array used in telecommunication applications. Its small size and high current and frequency ratings make it suitable for high frequency boost or buck regulators and for use in two or three stage forward converters. It is able to convert AC power to DC and is able to prevent energy loss due to the current flowing back into the AC source. It has a high maximum forward bias surge current rating and a high thermal resistance rating as well, making it a good choice for high-powered rectification applications.
