CZRU4V7B-HF Datasheet/PDFOverview
The CZRU4V7B-HF is a single Zener diode with an incredibly robust package, specifically designed to be used in a variety of applications. Due to its Advanced Silicon OxyNITRIDE Passivated Junction Structure and its ability to operate in an environment with a maximal steady-state power dissipation up to 1.3 Watts, it is ideal for both commercial and industrial applications. This Zener diode features an alloy junction, a maximum operating temperature rating of 175 degrees Celsius, and a maximum reverse voltage of 7.5 V.
Application Field
The CZRU4V7B-HF is often used in voltage regulation and surge suppression applications. Due to its optimal thermal resistance, it is capable of withstanding an incredible amount of heat that is generated when the power pass is heavy. This makes it an ideal display solution for both commercial and industrial applications. Its incredible thermal dissipation capabilities also make it useful in applications where a higher voltage output is desired.
The CZRU4V7B-HF is also extremely useful in temperature-sensing applications, such as in temperature monitoring systems, where it can accurately detect temperatures within a certain range and activate a thermoelectric device, such as a heat-pump, to maintain high temperatures. Furthermore, it is often used in emergency circuit protection due to its ability to regulate the current at a certain level when the input voltage is varying.
Working Principle
The CZRU4V7B-HF is basically a solid-state component that works similarly to a thermistor. In operation, the Zener diode creates an avalanche breakdown, which can regulate the ohmic resistance to keep the current flowing in one direction. When the voltage passes a certain threshold, the breakdown occurs, allowing the current to be restricted.
Elements such as the type of semiconductor material, the thickness of the depletion region, and the junction temperature will all determine the breakdown voltage. As a result, when the input voltage exceeds the breakdown voltage, the diode causes the current to flow in one direction and regulates the current, allowing the user to set the desired voltage output.
Conclusion
The CZRU4V7B-HF single Zener diode is an excellent choice due to its impressive thermal performance and its ability to regulate current and voltage in a variety of applications. Additionally, its alloy junction and robust package make it ideal for commercial and industrial applications.
