Diodes have been a critical component throughout the history of electronics, providing a reliable and efficient means to match a range of component applications. The SDUR60P60WT is a state-of-the-art rectifier array that integrates Schottky diodes into a range of configurations. The sophisticated architecture of this rectifier complex provides a remarkable ability to match a wide range of application requirements.

The SDUR60P60WT contains six Schottky diodes, matched and integrated into a three-phase configuration. This configuration allows lower voltage operation and improved efficiency compared to standard silicon diode rectifiers. Each phase of the device has its own reverse voltage protection, allowing it to handle high current levels at a nominal 18V DC input. The SDUR60P60WT also features a unique bridge design that reduces the common mode EMI generated by rectifier arrays during switching operations. This is especially important in applications where the presence of EMI can cause unwanted noise or unintentional interference with other microelectronic components.

The various components of the SDUR60P60WT and their respective roles in the overall operation of the rectifier array are described below.

The Schottky Diode

The Schottky diode is a type of diode that contains a metal-semiconductor junction instead of a p-n junction. This allows for substantially lower voltage drop across the junction, the result being improved system efficiency at low operating voltages. The SDUR60P60WT uses six Schottky diodes that are integrated into its three-phase configuration, resulting in improved efficiency compared to standard silicon diode rectifier arrays.

The Gate Turn-Off Switch

The gate turn-off switch (GTO) is used to control power to the rectifier array. In the SDUR60P60WT, the GTO includes a reverse voltage protection feature that prevents current from flowing backwards through the device. This is especially useful in applications that involve high current levels. The GTO also ensures that the rectifier array switches quickly and efficiently.

The Low Noise Driver

The low noise driver is used to control the gate turn-off switch. It is responsible for taking the input voltage and turning it into a user-defined output voltage profile. This is done by controlling the gate turn-off switch with precision, resulting in low switching speed noise and lower EMI generation.

The Voltage Regulator

The voltage regulator is responsible for providing the proper voltage level to the diodes. It ensures that the Schottky diodes are operating within the specified range, which results in improved efficiency. The voltage regulator also offers reverse voltage protection and over-temperature protection.

The Bus Bar

The bus bar is used to connect all of the components of the rectifier array to each other. It ensures a reliable electrical connection between each component, allowing the rectifier array to function correctly. The bus bar also helps to dissipate heat, which is necessary for a reliable operation in high power environments.

Application and Working Principles

The SDUR60P60WT rectifier array is a great solution for applications that require a reliable and efficient means of rectifying AC current into DC current. The integrated Schottky diodes allow for improved efficiency and lower voltage operation, while the reverse voltage protection and low noise driver ensure reliable operation in high current environments. The voltage regulator and bus bar provide further reliability and safety, making the SDUR60P60WT an ideal rectifier solution for a variety of applications.
