Diodes are commonly used in circuits for a variety of purposes, including amplification, rectification, voltage regulation, and signal switching. In most cases, two diodes are needed to form a complete circuit. Zener single diodes are unique in that they are capable of regulating the voltage in circuits, making them very useful in a variety of applications. In this article, we will focus on the application field and working principle of one type of Zener single diode, the BZD27B200P-E3-18.

Application Field

The BZD27B200P-E3-18 Zener single diode is designed to be used in low-voltage to medium-voltage applications. It has a wide range of operating temperature ranges, from -65°C to +200°C, making it suitable for many different types of electronic systems. It can be used in circuits for high-frequency switching, voltage switching, voltage regulation, and signal conditioning. This single diode is also used in applications where a high level of protection against Short Circuit and Overload effects is required.

Working Principle

The Zener effect is the basis for the operation of the BZD27B200P-E3-18 Zener single diode. This phenomenon occurs in semiconductor rectifier devices when a reverse voltage greater than the breakdown voltage of the device is applied. This causes an increase in the electric current running through the diode, resulting in a stabilized output voltage and current. This effect is simply known as the Zener voltage.

The BZD27B200P-E3-18 Zener single diode utilizes this Zener effect to regulate the voltage in a circuit. It works by allowing current to flow in the forward direction, but when a reverse voltage reaches the Zener voltage, the current is forced to flow through a second diode. This second diode provides reverse active protection, which acts as a clamp to limit the voltage output. In this way, the BZD27B200P-E3-18 acts as a voltage regulator, ensuring that the output voltage does not exceed the maximum rated working voltage.

Conclusion

The BZD27B200P-E3-18 Zener single diode is an excellent choice for low to medium voltage applications due to its wide temperature range and high level of protection. It can be used in circuits for high-frequency switching, voltage switching, voltage regulation, and signal conditioning. The diode is capable of regulating the voltage in circuits by utilizing the Zener effect, which allows for a stabilized output voltage and current.
