TZQ5231B-GS18 Datasheet/PDFDiodes - Zener - Single
The TZQ5231B-GS18 is a single Zener diode in a SOD-123 package, ideal for a wide range of applications. It is a single Zener diode that is used for surge protection and for controlling the stress applied to the system. The TZQ5231B-GS18 has a breakover voltage of 5.6 V, with a maximum forward voltage of 1.3 V, a power rating of 50 mW, and a maximum reverse current of 1.0 mA.
Application Field
The TZQ5231B-GS18 can be used in a variety of applications, such as surge protection circuits and voltage regulator circuits. It can also be used as an effective protection device in high-frequency circuits, such as radio receivers and transmitters, since it can handle very high surge and reverse voltage. The TZQ5231B-GS18 can also be utilized in automotive applications, such as in the protection of vehicle electronics. It is also ideal for circuit protection, such as in the protection of CPUs, high-power converters, and other sensitive components.
Working Principle
The TZQ5231B-GS18 works on the principle of a Zener diode, which is an unidirectional device that allows current to only flow from anode to cathode. It works by preventing a reverse current from flowing, which is followed by a breakover voltage when the voltage reaches a certain level. This breakover voltage is when the Zener diode suddenly allows current to flow in the reverse direction. This is followed by a “Zener effect,” where the reverse current quickly drops and the voltage remains consistent.
When a Zener diode is operating in reverse bias mode, it acts as a voltage regulator. A reverse current is applied and when the voltage reaches the breakdown voltage of the Zener diode, the Zener effect occurs. This creates a stable voltage level, which is ideal for many applications, such as voltage regulators in appliances, or as a voltage reference in logic gates and oscillators.
The TZQ5231B-GS18 also works effectively in high-frequency circuits. The diode\'s low forward voltage helps protect against surges and rapidly decreasing reverse voltages. These surges can be caused by any sudden overvoltage in the circuit, such as a lightning strike or an electromagnetic pulse. The TZQ5231B-GS18 is able to withstand a reverse voltage of up to 5.6 V, making it an effective protection device for any system.
Conclusion
The TZQ5231B-GS18 is an effective single Zener diode ideal for a wide range of applications. It is used in surge protection circuits and voltage regulator circuits, as well as in high-frequency circuits. It works on the principle of a Zener diode, which allows current to only flow in one direction, followed by a breakover voltage when the voltage reaches a certain point. The TZQ5231B-GS18 is also able to withstand a reverse voltage of up to 5.6 V, making it an ideal protection device in any system.
