The Working Principle of the CDSW4448-G

The CDSW4448-G is a rectification device which consists of two half-pitched components, an anode and a cathode. It’s basically a junction diode made up of semiconductor materials, such as gallium arsenide (GaAs), silicon (Si) or germanium (Ge). It has a characteristic do-shape cross-section which allows it to pass electric current in one direction.

In order to achieve forward biasing, the anode of the diode must be physically connected to the positive terminal of the power supply, while the cathode is connected to the ground or negative terminal of the power supply. Similarly, reverse biasing requires the anode to be connected to the negative terminal of the power supply and the cathode to the ground or positive terminal of the power supply.

In forward biasing mode, the electric current passes through the diode effortlessly and in a uniform manner. This state is referred to as the low resistance state. Whereas, in reverse biasing mode, the electric current is blocked from passing through the diode since the diode offers a high resistance to this current. As the electric current passes through the diode, it is modified to better serve the purpose of the application.

The CDSW4448-G is highly reliable and offers high performance even with changing temperature conditions. To reduce EMI, it is also equipped with ESD protection capability. It has also been designed with a special Isolation Zone structure which provides robust insulation for voltage, current and temperature rise.
