The device has an reverse breakdown voltage of 18 volts and is suitable for a wide variety of applications, including interface protection, high-power regulators, and surge protection.In this article, we will discuss the applications and working principle of the TDZTR18B Zener diode.ApplicationsThe TDZTR18B is ideal for medium-power applications. It can be used to protect circuits and components against large overloads. It is used in interface protection, high-power regulators, surge protection and other applications where its reverse breakdown voltage of 18 volts is needed.The TDZTR18B is also suitable for use in series with resistors to provide an adjustable voltage reference source. This is often used in power supplies and other regulators for precision voltage reference.The TDZTR18B can also be used in voltage multiplication circuits, where its reverse breakdown voltage of 18 volts allows for multiple voltage levels to be created from a single power source.Working PrincipleThe TDZTR18B Zener diode has a reverse breakdown voltage of 18 volts. This is the voltage at which the diode begins to conduct in the reverse direction.When the voltage across the diode reaches the breakdown voltage, current will begin to flow in the reverse direction. This current flow is limited by the resistance of the diode, thus creating a stable voltage across the diode that is equal to its breakdown voltage.The TDZTR18B can handle up to 1 watt of power in its reverse breakdown state. This means that it can handle large currents without burning out or failing.ConclusionThe TDZTR18B Zener diode is ideal for medium-power applications. It is specifically designed for a wide range of uses, providing excellent power handling and guaranteed protection against large overloads. The device\'s reverse breakdown voltage of 18 volts is suitable for a wide range of applications, including interface protection, high-power regulators, and surge protection. The TDZTR18B is also perfect for use in series with resistors to create precision voltage references, as well as for use in voltage multiplication circuits.
