CDSU400B is a type of single rectifier diode commonly used in many circuits. It is a three-terminal device with two anodes and one cathode: the anode is marked with the letter A, the cathode is marked with the letter K, and the common terminal is marked with a dot. The diode has an outstanding surge capability, making it suitable for use in harsh environments and applications where the operational voltage is higher than expected.

The CDSU400B has a voltage breakdown of 400V, with a maximum reverse voltage of 200V. It has a forward current of 4A, a maximum repetitive peak reverse voltage of 600V and a maximum reverse recovery time of 10µs. Its peak-temperature coefficient of the forward voltage is 0.009V/K and a maximum operating temperature of 175°C.

The working principle of the CDSU400B is very simple. When forward biased, it acts as a closed switch and allows electrical current to flow from the anode terminal to the cathode terminal. This is possible because the diode is embedded with an intrinsic layer of P-type material between the two terminals and because it is manufactured with an impurity concentration gradient which, when exposed to forward bias, allows electron depletion and current flow. When the reverse bias is applied, the electric current is blocked, because the depletion layer extends to the entire junction and electrons cannot get across.

The CDSU400B can be used in numerous applications, such as full-wave rectification, motor control and AC/DC motor speed control. It is also suitable for applications related to Zener diode regulation, frequency modulation and oscillators, as well as electronics switch in either on or off mode. In addition, the diode can be used in lighting systems, telecommunication and automotive industries.

For maximum performance and reliability, it is very important to consider some important parameters when selecting the CDSU400B, such as the peak repetitive reverse voltage and maximum operating temperature. A good understanding of these parameters is also essential for an efficient assembly.
