Working Principle

The ESH3DHE3_A/H diode rectifier is a three-terminal diode rectifier module that features an isolated baseplate, a high-speed soft-recovery silicon diode, and an integrated boost inductor. The module is designed to provide low EMI noise, high-efficiency power conversion, and low-voltage stress. The three-terminal design eliminates the need for an external snubber network, resulting in reduced cost and simplified design.

The device operates by passing a current pulse through the integrated boost inductor and then through the two cathode nodes, resulting in a voltage drop across the three terminals. This voltage drop allows the rectifier to efficiently convert the pulsed current into a continuous DC current, as required by the application. As the current passes through the rectifier, the EMI noise associated with the current is reduced significantly, thus leading to higher efficiency and improved power quality.

In addition to the three-terminal configuration, the device also features adjacently mounted thermistors which help to reduce junction temperature during sustained operation. The diode features an integrated temperature sensor, allowing for accurate control of the junction temperature. This feature helps to ensure reliable operation even in demanding high-temperature environments.

Conclusion

The ESH3DHE3_A/H diode rectifier is a robust high-efficiency rectifier solution designed to offer a variety of performance advantages over traditional two-terminal rectifier solutions. Thanks to its three-terminal configuration, integrated boost inductor, and adjacently mounted thermistors, the device is able to provide efficient, low-noise rectification for a variety of power conversion applications.
