Working Principle

The working principle of CMSH2-100 TR13 is based on the physics of thermionic emission. A thermionic emission occurs when a hot cathode releases electrons into its surroundings due to the higher temperature. The thermionic emission is dependent on a number of factors, such as the material of the cathode and its work function, the temperature at which it is operated and the applied electric field. The electrons traveling from the cathode are known as thermionic electrons. These thermionic electrons traverse the space between the cathode and the anode and recombine with the positive ions in the space.

To keep the thermionic emission occurring, the temperature of the cathode has to remain high. This is achieved by the application of an electric field across the diode junction. This electric field causes electrons to be released from the cathode side, while the positive ions move towards the anode side. This phenomenon is known as the avalanche breakdown effect and is the basis of rectifier diodes. The electrons are then either passed through or blocked, depending on the polarity of the electric field. In the case of CMSH2-100 TR13, the electrons are blocked when the electric field is in one polarity and passed through when the electric field is in another.

Conclusion

The CMSH2-100 TR13 is a low voltage drop single rectifier diode, designed to offer high surge current capability and have a high power density. Its applications range from automotive systems to industrial power supplies and high efficiency switching power supplies. The working principle of the rectifier diode is based on thermionic emission, in which the electrons are blocked when the electric field is in one polarity and passed through when the electric field is in another.
