TZQ5238B-GS08

Diodes - Zener - Single

The TZQ5238B-GS08 is a single zener diode. It is mainly used for stabilizing and clipping circuits to provide a reference voltage, or overvoltage protection.

Application Field of TZQ5238B-GS08

The TZQ5238B-GS08 is widely used in various fields, such as in precision regulators, transistor saturators, peak limiting circuits, or television receivers. Other uses are in power supply circuits, telephone line protection, static short-circuit protection, and clipping circuits.

Working Principle of TZQ5238B-GS08

The TZQ5238B-GS08 works by taking advantage of the voltage versus current "knee" in the Zener breakdown region (also known as Zener effect). The Zener breakdown region is the characteristic in which when the applied voltage exceeds the specified breakdown voltage (VZ) of the component, a sudden increase of current is experienced as the component attempts to reduce the applied voltage difference. This sudden increase of current is limited by external components.

When the component is turned on, a forward current (IF) is established by the component, and a reverse current (IR) is provided by the external components to maintain the component within the breakdown region (i.e., keep the voltage at or below the VZ rating). This reverse current is what allows the component to provide a constant reference voltage. As the load conditions change, the component adjusts its current to maintain the VZ voltage.

Advantages and Maintenance of the TZQ5238B-GS08

The TZQ5238B-GS08 is particularly attractive due to its high power and temperature ratings. The component is also relatively low cost and can easily be integrated into modern digital designs. The component is designed to be maintenance free, but care should be taken to ensure that it is not overstressed. It is important to ensure that the component is not subjected to voltages greater than the VZ breakdown voltage and that the power dissipation rating is not exceeded.

The TZQ5238B-GS08 has proven to be a reliable and versatile single zener diode that can be used in a variety of applications. With the proper care, the component can provide years of reliable service.
