CDBMH180-HF Application Field and Working Principle

Diodes - Rectifiers - Single

CDBMH180-HF is a single diode-rectifier product with a forward current of 180A and a forward voltage range of 250V to 600V. It is a surface mount device that features high frequency performance, low reverse leakage current, and very low forward voltage drop.The CDBMH180-HF can be used in a wide range of applications, including AC-DC power conversion, DC-DC power conversion, switched-mode power supplies (SMPS), laptop chargers, LED lighting, and automotive applications.

Basic Working Principle

The working principle of the CDBMH180-HF is based on a simple diode-rectifier circuit. When a voltage exceeding the forward voltage drop is applied across the two terminals of the device, electrical current passes through the device. This current passes through the junction of two dissimilar semiconductors (p-type and n-type), also known as the PN junction, which creates a diode-like effect.When a positive voltage is applied, current passes through the junction and charges up the PN junction. This charge prevents the current from passing in the reverse direction, creating the diode’s rectification effect. The voltage across the two junctions builds up to the forward voltage drop when the current reaches the device’s maximum forward current limit of 180A.

Additional Features

Aside from its basic rectification properties, the CDBMH180-HF also offers some additional features that improve its performance:

• Low Reverse Leakage Current. The device is designed to have a very low reverse leakage current, which is important for efficient operation.
