The BZX84C47ET1 is a zener diode from Swedish manufacturer, Larsen, that has a wide range of applications. It is also commonly used for voltage regulation and in low current applications. In this article, we will look at the application field and working principle of the BZX84C47ET1.

Application Field

The BZX84C47ET1 is specifically designed for use in low-current applications. It is suitable for soft start and overload protection, as well as providing voltage regulation. This diode can provide a stable voltage output in AC supply systems and can handle up to 1.5W of power.The BZX84C47ET1 is a very reliable device and has a high efficiency with minimum noise. It is used in many circuits as it is easy to design, install, and maintain. It provides protection against short circuits and over-currents and is commonly used in power systems.

Working Principle

The BZX84C47ET1 is an N-channel zener diode that works on the principle of reverse biasing. It has a limited reverse breakdown voltage, and when the voltage across the diode is greater than the breakdown voltage, an avalanche breakdown occurs, allowing current to flow. In the off state, no current flows and the device acts as an open circuit. The voltage applied to the diode is regulated by the controlled breakdown voltage of the device. This breakdown voltage is determined by the doping level of the semiconductor material used in the device. The BZX84C47ET1 can provide very stable voltage output in both AC and DC applications, and it has low output impedance and good temperature stability. This makes it a good choice for voltage regulation.

Conclusion

The BZX84C47ET1 is a zener diode from Larsen that is commonly used in low-current applications for voltage regulation, overload protection, and soft start. It works on the principle of reverse biasing and has a controlled breakdown voltage determined by the doping level of the semiconductor material used in the device. It has a good response time, low output impedance, and high efficiency with minimum noise. It is easy to design, install, and maintain and provides protection against short circuits and over-currents.
