Application Field

The STTH8R06D rectifier is designed to be used in ac-dc power converters, motor control, switched power supplies and other power management applications where high current and high voltage ratings are desired. The device also helps reduce losses in applications where high switching frequency are employed.

It is mainly used in appliance control, ballast/ lighting control, dimming/ LED lighting, pulse/ brushed motor control, welding power control, uninterruptible power supply, switched mode power supply, power factor correction and solar/ wind power control applications. It has extended temperature operation range of 0°C to 70°C, which makes the device suitable for use in high temperature and harsh industrial environment.

Working Principle

A rectifier is a device or tool designed to convert an alternating current or AC signal into a direct current or DC signal. The major component of the STTH8R06D bridge rectifier is the Schottky diode which is a semiconductor rectifier. It operates on the principle of majority carriers. This means that the electrons flow across the entire width of the semiconductor, allowing the device to operate at lower voltages and higher current levels than more traditional rectifiers.

The Schottky diode also acts as a very fast switch, allowing it to be used in applications involving higher switching frequency which in turn leads to improved efficiency. The device\'s low forward voltage drop also contributes to improved efficiency. The device requires no external diodes or components for operation, making it compact and easy to use.

The STTH8R06D bridge rectifier is designed to cope with very high operating temperature conditions and its large junction temperature range ensures that its operation is reliable in extreme temperatures. The device has a maximum current rating of 8A and a maximum voltage rating of 800V.

The device has a reverse leakage current of less than 50nA, which is important to its efficient operation because it helps to reduce power loss. This device is also relatively inexpensive, making it an economical choice for power applications.

In conclusion, the STTH8R06D single-phase bridge rectifier is the ideal choice for applications requiring high current and high voltage ratings, as well as improved efficiency and low cost. This device is suitable for power supply systems, power electronics circuits, switched-mode power supplies, capacitive and inductive loads, and other similar applications.
