A SDURD530TR is a single-phase, ultrafast reverse recovery rectifier diode. This package is suitable for automated assembly through the use of infrared and vapour phase reflow soldering. It is made with a high temperature alloyed construction and features a high current capability and low power losses in switching applications.

SDURD530TR’s application field includes power supplies, DC/AC inverters, VSDs, and all kinds of high frequency circuits. It is an ideal choice for industrial applications with medium voltage requirements and high current load.

The device is designed to provide efficient and fast conduction of current for use in applications such as solar inverters, UPS systems, power supplies and other power control applications. The built-in protection feature allows the device to protect the device from over-current and over-voltage stresses.

The SDURD530TR rectifier diode’s operating principle is based on the controlled recombination of minority carriers. When a forward current passes through the diode, electrons and holes recombine, causing the voltage across the diode to drop rapidly. This creates a fast reverse recovery current pulse which provides improved power efficiency.

The diodes’ reverse recovery properties are also improved by the use of diffusion capacitance. This capacitance helps to limit current to a defined limit and improves reliability over applications in repetitive cycling operations. The devices also feature low leakage current and are designed to operate in high temperature applications.

In order to ensure optimal performance, the SDURD530TR includes a high power Silicon chip which allows the device to efficiently survive repetitive stressing conditions. The chip also ensures the device can operate continuously in high temperature environments.

The SDURD530TR device is also designed to provide optimised surge capability and improved reliability in applications that require switching at high frequency and in high temperature conditions. The built in heat sink offers improved heat transfer for higher current applications.

The SDURD530TR integrates a fast and efficient reverse recovery time and improved surge capabilities. It also has a high frequency operation and a low on-state turn-on time for improved system efficiency. Combined with a robust design and high temperature tolerance, this product becomes an ideal choice for a range of applications.
