BZX55F20-TR

BZX55F20-TR Application Field and Working Principle

The BZX55F20-TR is a single, low-noise, Zener diode manufactured by Vishay Semiconductor. It is mainly used for voltage regulation, voltage measurement, and overvoltage protection.

The BZX55F20-TR diode is capable of handling currents up to a maximum of 100 mA and is available in a wide variety of voltages from 5.1 V to 200 V. It also features a low reverse leakage current of a maximum of 100 µA and a low noise level of 400 nV/√Hz. The device is packaged in a SOD-123 package.

The working principle of the BZX55F20-TR diode is based on the Zener diode principle. The diode works like a normal diode when current is flowing in the forward direction. When a voltage greater than the breakdown voltage is applied to it, current starts to flow in the reverse direction. This is known as the Zener breakdown phenomenon. The Zener diode is designed to have a reverse breakdown voltage in a specific range, thus allowing it to be used in applications such as voltage regulation and protection from overvoltage.

The BZX55F20-TR diode is mainly used for voltage regulation and overvoltage protection. In voltage regulation, it is used for providing a constant voltage even when the external power source varies. This is done by applying the desired voltage across the diode, and then by controlling or limiting the current by inserting a resistor in series. This allows the device to provide a constant voltage. In overvoltage protection applications, the diode is used to protect an electronic circuit from being damaged due to high voltages. When the voltage across the Zener diode exceeds the breakdown voltage, the diode will conduct current and limit the voltage to the breakdown voltage, thus preventing the circuit from being damaged.
