CGRM4001-G Discrete Semiconductor Products

CGRM4001-G is a general purpose silicon rectifier with integrated guardring for overvoltage protection. It is a single-phase, silicon series connection device that is mostly used for general purpose and Hobbyist applications.

The CGRM4001-G is capable of rectifying power and currents up to 400V and 1.0A respectively. These rectifiers are composed of four branches: Anode, Cathode, Guardring, and Leadframe. The anode and cathode agree to the same diffusion physics principles. The intrinsic resistance of the anode and cathode terminals are determined by their length, thickness and doping level. Similarly, the guardring features a higher doping level as compared to anode and cathode. The leadframe plays an important role in both adhesion of the guardring and the layout of the package.

Essentially, the CGRM4001-G rectifier consists of a single diode connected between two terminals, the anode and the cathode. When a voltage is applied, the electric current is allowed to flow from the anode to the cathode. This allows the rectifier to equip a current of higher magnitude as compared to normal diodes. The current is controlled by varying the voltage, and the rate of current flow is determined by the resistance between the anode and the cathode. The current will naturally encounter a much higher resistance when trying to flow from the cathode to the anode, thus preventing current from deviating in the opposite direction. This component is mainly used in voltage regulation, AC peak detection, rectification of power supplies, and the regulation of pulsed signals.

The CGRM4001-G features a thermal pad and leadframe construction, allowing quick thermal dissipation and sustaining long-term reliability. It is capable of operating in temperatures up to +175C without compromising its power ratings. This rectifier is best suitable when installed on magnetic substrates and copper surfaces for better performance and stability. Furthermore, the mounting format for the CGRM4001-G is TO-220 IS, which is small and compact, making it both easy and reliable to install.

In conclusion, the CGRM4001-G is an excellent choice for general purpose and hobbyist applications and is a strong and reliable component in low voltage and current stages. Its low thermal and electrical losses, along with its robust thermal design, makes it an ideal choice for rectifier needs in these areas.
