Introduction

CZRSC55C4V7-G is a single Zener diode from C3 Technologies that features an impressive range of features including enhanced maximum power dissipation, an extended reverse leakage current range, and a significantly improved voltage coefficient. In this article, we will discuss the application fields and working principle of CZRSC55C4V7-G.

Application Fields

CZRSC55C4V7-G is most commonly used in applications where an enhanced peak power dissipation, improved temperature stability, and a strong reverse leakage are required. These applications include electronic meter performance, power supply design, automotive electrical system design, and precision voltage regulation. It is also a great choice for use in general purpose applications that require nominal power dissipation.

Working Principle

The CZRSC55C4V7-G is a single Zener diode which operates on the principle of reverse breakdown voltage, also known as avalanche breakdown. This works when excessive current is forced through a P-N junction, thereby creating a depletion region that allows the electrons to cross the junction. The greater the applied electric field, the lower the resistance and the greater the current flow. When this current reaches the diode\'s threshold, it causes the diode to go into the reverse breakdown voltage mode and thus the voltage keeps increasing until it reaches the Zener voltage. This excessive current and voltage then produces a discharging effect between the anode and cathode of the diode and stabilizes the reverse voltage that appears across it.

Conclusion

CZRSC55C4V7-G is a single Zener diode from C3 Technologies that features an impressive range of features including enhanced maximum power dissipation, an extended reverse leakage current range, and a significantly improved voltage coefficient. It is most commonly used in applications where an enhanced peak power dissipation, improved temperature stability, and a strong reverse leakage are required. Its working principle is based on the reverse breakdown voltage, which allows for the control of the voltage and current that appears across it.
