MBRD320T4G Discrete Semiconductor Products

The MBRD320T4G is a rectifier diode within the single diode family. It is typically used as an input rectifier to boost power factor and its associated power applications. The diode is also used to limit the reverse voltage on inputs and outputs.

The MBRD320T4G is a silicon junction epitaxial rectifier. It consists of a single silicon injection layer (epi layer) and a single ultra thin junction layer (sub layer). The rectifier has a maximum reverse voltage rating of 300 volts (V), a maximum forward current rating of 320 amp (A) and an average forward current rating of 1.2A. Its maximum forward voltage drop is 0.8V.

The application fields of MBRD320T4G involve device protection from electrical spikes and small impulse current. It is used as a surge protector in consumer electronics and industrial machinery. The diode also finds application in motor circuits to reduce the noise generated by the engine, as it limits the current flow through the inductor.

The working principle of the MBRD320T4G is to accept and hold only a designated level of current at the point of contact until it encounters the reverse voltage threshold. When the reverse voltage threshold is reached, the diode shuts down and holds the current, preventing further voltage from entering the circuit. This provides protection from excessive current in the circuit.

The MBRD320T4G also serves as a switch in a power converter. When in the “on” state, the diode will allow current to flow, boosting the power factor. When in the “off” state, the diode will not allow current to flow, thus limiting the power factor. It is also used as a voltage clamp in power supplies to limit the voltage potential across the device.

The MBRD320T4G is a popular choice of rectifier diode due its high current capabilities, small size, and excellent surge protection. The diode is reliable and efficient in its application fields and provides a great amount of protection in electronic circuits.
