Introduction to BZT52B47-HE3-18 Diodes - Zener - Single

The BZT52B47-HE3-18 is a single diode that belongs to the Zener series. It is manufactured by STMicroelectronics and is mainly used for the purpose of voltage regulation. It is a surface mountable device that comes in a small 2-pin package. The device is capable of dissipating 180mW of power and can operate at temperatures ranging from -55℃ to 125℃.

Application Field and Working Principle

The BZT52B47-HE3-18 diode is mainly used in voltage regulation applications. They are one of the few components which can maintain the output at a constant voltage across a wide range of input voltages. This makes them perfect for applications such as battery backed supplies, power supplies, and voltage references. They are also commonly used in voltage clamping and current limiting circuits.The working principle of the Zener diode is similar to that of a normal diode. When a forward voltage is applied, it starts to conduct current. However, when a reverse voltage that exceeds the diode’s breakdown voltage is applied, the diode will start to conduct current in the reverse direction. This is done in order to regulate the voltage across the diode and thus maintain the voltage at the desired level.

Features

The BZT52B47-HE3-18 has many features which makes it an ideal choice for voltage regulators. It has a breakdown voltage of 5.1V, which allows it to regulate a wide range of voltages. It also has a low temperature coefficient of -0.05V/℃, which ensures stable regulation even during temperature variations. Its small size and lead free design also make it perfect for use in modern circuit designs.

Conclusion

The BZT52B47-HE3-18 diode is a versatile component which can be used in a variety of different applications. Its ability to regulate a wide range of voltages makes it ideal for use in voltage regulation circuits. It can also be used in voltage clamping and current limiting circuits.
