Diodes - Rectifiers - Arrays

MBRF30H50CTHE3/45 is the part number for an array, a type of rectifier diode. A rectifier diode is an electronic component that consists of an anode and a cathode, and increases the flow of electricity in one direction when a voltage is applied. Although diodes generally use two dissimilar materials, if two identical materials are used, they form a diode array.

Application

A diode array such as the MBRF30H50CTHE3/45 is often used in applications such as television circuits, CATV, satellite receivers, communications systems, birdcalls and radios. The diode array has a higher yielding current capacity than traditional diodes, and its ability to withstand inrush currents without failing likewise exceeds the capacity of a standard diode.

Working Principle

As mentioned earlier, a diode array consists of two identical materials, which are typically silicon. These two materials are joined in a single junction, and the materials combine to form a PN junction. This PN junction is essential to understand the process of conduction, rectification and signal isolation.

The MBRF30H50CTHE3/45 represents the mesa design of a diode array. This design allows each diode to be connected in parallel with one another, to form an array. The array is then connected in a series, creating a single large diode. Thus, MBRF30H50CTHE3/45 allows multiple isolated diodes to be connected in series, achieving the same effect as a single large diode.

In this design, the current passes through the connecting wire between the two PN junctions. As the voltage changes, the current is then rectified, as the circuit acts as a filter, allowing the current to flow through in only one direction. As such, a voltage spike generated by a television, radio or other electrical circuit can be easily rectified and isolated to power the circuit without suffering any damage.

The MBRF30H50CTHE3/45 diode array is ideal for applications that require a high voltage spike, a high current rating and reliable rectification. It can be used in consumer electronics and other applications that require a reliable, large capacity diode.
