Introduction to UH2D-E3/5BT Rectifier

UH2D-E3/5BT is a single rectifier diode module with a plastic case and a series of interlocking tabs for easy mounting to a printed circuit board. It is designed for use in a wide range of applications where a single diode is needed for rectifying a variety of alternating voltages.UH2D-E3/5BT is manufactured by Toshiba and is their current flagship rectifier diode module. It has a number of features that make it ideal for use in a variety of applications. Among these are its high-efficiency, compact size and rugged design.

UH2D-E3/5BT Application Fields

The UH2D-E3/5BT rectifier diode is commonly used to provide uni-directional current in industrial and automotive applications. It can be used in high-power AC/DC converters, power supplies, inverters and DC-to-DC converters. The diode also sees use in the rectification of radio frequency (RF) signals, and in the generation of variable-voltage sources.In automotive applications, the UH2D-E3/5BT can be used for the rectification of voltage signals produced by electric motors and alternators. In this application, the diode must be capable of withstanding high frequency and high temperature.The UH2D-E3/5BT is also suitable for use in military and aerospace applications, due to its rugged design. It can be used in the generation of regulated voltage sources and for rectifying the signals generated by radar systems.

UH2D-E3/5BT Working Principle

The UH2D-E3/5BT rectifier diode works by passing current in only one direction. When the forward voltage exceeds the established reverse breakdown voltage of the diode, it begins to allow current to flow through it in the forward direction. As the forward voltage continues to increase, the current through the diode also increases.When the forward voltage decreases or current is removed, the diode begins to block current in the reverse direction. This is known as the "reverse recovery time" of the diode. After this time has elapsed, the diode will start to conduct in the reverse direction again.The UH2D-E3/5BT rectifier diode has a low forward voltage drop, making it ideal for applications that demand minimal power loss. The diode has a low reverse recovery time, allowing it to switch quickly and efficiently. As a result, it can handle high frequencies and high temperatures, making it suitable for use in high-power converter applications.

Conclusion

The UH2D-E3/5BT rectifier diode is a reliable, high-efficiency device for use in a wide range of industrial and automotive applications. Due to its low forward voltage drop and fast reverse recovery time, it can handle high frequencies and temperatures, making it suitable for use in power supplies, inverters, DC-to-DC converters and other applications.
