Diodes are semiconductor devices that allow electricity to flow with only one direction, and rectifiers are used to convert alternating current (AC) power into direct current (DC) power. Arrays of diodes in a rectifier bridge are known as rectifier bridges. The MBR30H100CT-E3/4W is a current-limiting rectifier bridge array that is constructed with two downward shielded MOSFETs and four rectifying diodes.

The MBR30H100CT-E3/4W is designed for applications where a large input-to-output voltage drop is required for maximum current protection, such as in automotive, telecom, and power supply systems. The device is designed to limit the fault current to 30A in the event of an output short circuit, enabling it to provide maximum protection to system components. The device also has temperature protection capabilities, providing over-temperature protection in the range of 125C to 150C.

The working principle of the MBR30H100CT-E3/4W is based on the four rectifying diodes forming a bridge rectifier that converts AC power into DC power. The four diodes are arranged in a square, with the two downward shielded MOSFETs placed on either side of the square. When power is applied to the rectifier bridge, the diodes conduct current in one direction, while blocking current in the reverse direction. This prevents power from flowing back into the AC source. The two MOSFETs limit the output current, preventing excessive current from being supplied to system components. This also helps protect the MOSFETs from thermal overload, as the MOSFETs are designed to handle up to 30A of current.

In applications where a high input-to-output voltage is required, such as in automotive, telecom, and power supply system applications, the MBR30H100CT-E3/4W is an ideal device to provide maximum current protection. The device is designed to limit the current to 30A, ensuring that no more than 30A of current is delivered to the system components during a short circuit event. The device also provides temperature protection, further protecting the system components from excessive temperature events.
