Diodes - Zener - Single

A Zener diode is a type of diode that allows current to flow in either direction and is used for voltage regulation and other applications. One type of single Zener diode is the TZM5254F-GS18.

Application of the TZM5254F-GS18

The TZM5254F-GS18 is a single Zener diode used in a variety of applications, such as voltage regulation, bidirectional overvoltage protection, and reverse bias protection. Thanks to its high reverse breakdown voltage of 18 volts, it is commonly used in circuits that operate at higher voltages. Additionally, it has an operating temperature range from -55 to +150°C and an operating power dissipation of 500 mW, making it suitable for use in a wide range of conditions and environments.

Working Principle of the TZM5254F-GS18

The TZM5254F-GS18 is a single Zener diode, which means that when the reverse voltage is below the Zener voltage, no current will flow. When the reverse voltage is above the Zener voltage, the Zener diode begins to conduct and current starts to flow. This current is limited by the internal resistance of the diode, so the voltage remains constant, allowing it to regulate the voltage.In addition, it also has its own internal nonlinear (“Zener”) breakdown characteristics. This breakdown characteristics is usually described as a linear voltage increasing exponentially when the reverse voltage is above the Zener voltage. This allows the diode to withstand a much higher reverse voltage than it is designed for, making it highly reliable and durable.

Conclusion

The TZM5254F-GS18 is a single Zener diode that is commonly used for voltage regulation, bidirectional overvoltage protection, and reverse bias protection. Thanks to its high reverse breakdown voltage, it can be used in circuits that require high voltages and its wide operating temperature range and power dissipation make it suitable for a variety of applications. Furthermore, its internal nonlinear “Zener” breakdown characteristics allows it to withstand higher voltages and make it highly reliable.
