The SDUR840 is a high-efficiency rectifier bridge with a single type construction that is suitable for switching frequency applications, providing excellent performance in an industry-standard package. The device is ideal for power control, overvoltage protection and multiple-phase rectification applications. It has been designed to provide a low-distortion voltage waveform with minimal power losses, enabling high efficiency applications.

The main characteristics of the SDUR840 are its low on-state resistance in parallel operation, low power loss in switching applications, and its low turn-on voltage. The device is also capable of supplying up to 20 A of current, and is able to operate with up to 0.5 A of continuous current. The device is rated at 40°C, and is capable of delivering 8 A @ 6V or 4 A @ 12V. There are also several other ratings available, allowing the device to be tailored to fit many different application requirements.

The SDUR840 is both efficient and reliable, and can be used in a wide range of applications, including power supplies, DC-DC converters, AC-DC converters, uninterruptible power supplies, motor drive power supplies, battery chargers, inverters and DC motor drives. It is well-suited for use in applications that require high frequency operation and a low voltage drop, as well as applications that require high efficiency and low noise.

The SDUR840 is a bridge rectifier, meaning it has four diodes that are connected in an alternating bridge-like pattern. This circuit configuration allows it to switch off during the negative half of the input power cycle, while allowing current to flow when the positive half of the input power cycle is applied. When the diode is in its conduction state, it operates with a voltage drop of around 0.45V, allowing for high-efficiency applications. The device can also operate at high switching frequencies, making it ideal for high-frequency applications.

The device contains built-in protection features, including built-in overvoltage protection and a thermal shutoff circuit. In addition, the device features a short-circuit protection circuit, which prevents the device from going into thermal runaway in an overload situation. The device also features polarity protection, which prevents the device from operating if the input polarity is reversed.

The SDUR840 is widely used in a variety of industries, from consumer electronics to large-scale industrial production. It is a versatile and cost-effective device, and allows for high efficiency and low losses, making it a popular choice for all manner of power control and rectification applications.
