Within the large category of diodes, zener types are a special type that offer some unique benefits for different application areas. The TZQ5241B-GS08 by Diodes Incorporated is a 300mW axial-format zener diode, designed primarily for voltage regulation and, within limits, clipper applications. Here, we aim to discuss the applications and working principle of this product.

Overview

The TZQ5241B-GS08 can be used as a voltage-regulating device, a series regulator and a clipper, depending on the circuit. It is offered in a DO-204AL axial package for convenient mounting and is capable of tolerating peak repetition reverse voltages of up to 25V. The desirable features of this product include a low dynamic impedance for fast response, and a low zener breakdown voltage for greater accuracy to meet the requirements of many different applications.

Applications

Notably, this zener diode is used in the automotive industries due to its reliable performance in similar applications. It is suitable for use in applications such as voltage regulation, current regulation, clipping and surge protection, depending on the particular circumstances. In terms of automotive and home application, it can be used to control the voltages, as it is designed for a nominal breakdown voltage of 5.1V with a tolerance of 5%. It is also used in the database, communications, sensing and measuring instrument industries, particularly in moments where a reliable protection would be needed.

Working Principle

A zener diode is a component that allows current to flow in either direction, depending on different operating conditions. Unlike other diode types, it has a reduced barrier voltage when connected in a reverse biased condition. This prevents any current from passing through the junction until the voltage reaches a certain level where the breakdown voltage occurs, hence the name "zener". This device is used in multiple applications depending upon its breakdown voltage, whereby its unintentional low power voltage regulation and advanced characteristics become advantages.

The TZQ5241B-GS08 follows the same principles as any zener diode. When the diode is forward biased, the current flows easily across the diode, as with any regularly biased diode. However, even reverse biased, it will still conduct current below the predetermined set breakdown voltage, thereby regulating the voltage in the circuit. The breakdown voltage can be determined by the position of the components within the integrated circuit. When the voltage is reached, the current will be the same regardless of whether the voltage continues to increase.

Conclusion

The TZQ5241B-GS08 diode is a single zener diode that is used in multiple applications. Its ability to withstand a peak repetition reverve voltage of up to 25V and breakdown at a predetermined voltage makes it a useful device for voltage regulation, clip limiting and surge protection. The zener diode works by allowing a current to flow in either direction, depending on the set operating conditions, and switching off once it reaches the predetermined set breakdown voltage.
