UH2DHE3_A/I application field and working principle

UH2DHE3_A/I is a type of high-voltage rectifier diode, which is mainly used in harsh environmental applications that require reliable performance. It provides a rugged unidirectional current conduction with high electrical stability in high temperature applications, such as car ignition systems, automotive airbags, and motor control systems. It is also used in applications that require high overvoltage protection, such as power supply systems and communication networks.

Working principle

A UH2DHE3_A/I rectifier diode consists of two p-type and two n-type semiconductor regions, which are separated by a thin layer of an insulating material. When an external voltage is applied to the device, current flows from the P-type region to the N-type region, producing a rectified current waveform. The process is known as rectification, and the UH2DHE3_A/I diode is designed to allow current to pass only in the forward direction.

The major distinctive feature of the UH2DHE3_A/I rectifier diode is its high voltage and temperature capability. This enables it to maintain a high level of reliability and performance in high-temperature applications, where the performance of other rectifier diodes may become compromised. The UH2DHE3_A/I diode can operate over a wide range of voltages, from several hundred volts up to a few thousand volts, with a reverse leakage current of less than 100μA.
