CDST-21A-G Application Field and Working Principle

CDST-21A-G (Common Cathode Surface Mount Rectifier Array) belongs to the Diodes - Rectifiers - Arrays family. It is a small signal rectifier array with very low voltage drop, extremely low incremental-capacitive-current, fast reverse-recovery time, and radiation hardening. It is available in different versions such as uni-directional, two-terminal, and three-terminal edge card type.

CDST-21A-G has two terminals in a single package, including an anode and a common cathode. CDST-21A-G can be applied in many different fields, such as communication, electronic industry, and automation. When used, the anode of CDST-21A-G should be directed to the positive power sources, and the cathode should be grounded.

CDST-21A-G\'s working principle is to provide very favorable leakage paths for electrons. The anion in the empty space of CDST-21A-G\'s p-type material will be attracted by the anode, while the electron in the n-type material will be attracted by the cathode. As the resistance of the p-type material is much higher than the n-type, the majority of the electrons will flow through the n-type material, making it a low-resistance path for current to flow through.

CDST-21A-G also has very fast reverse recovery time. Due to its small size and low capacitance, it can rapidly switch between anode and cathode, allowing current to flow through swiftly. Furthermore, it has very low incremental-capacitive-current, preventing large voltage drops between the anode and cathode.

Due to its outstanding performance, CDST-21A-G is widely used in applications such as low-power switching, automotive applications, medical and healthcare equipments, industrial automation, sensors, and instrumentation. In addition, since it has built-in radiation hardening, it is also suitable for aerospace applications in which radiation protection is necessary.

In conclusion, CDST-21A-G is a reliable and efficient low-power rectifier, which can be widely used in different fields due to its favorable features. The combination of its anode and common cathode, radiation hardening, and fast reverse recovery time makes it an ideal choice for a variety of applications.
