ACZRA4762-HF

Diodes - Zener - Single:

The ACZRA4762-HF is a single zener diode that is used to regulate a specified voltage level and protect against excessive current flow. It works by using reverse conduction and a breakdown voltage that turns it into a current regulation device. Zener diodes are designed to have a low leakage current and have a low temperature coefficient. The ACZRA4762-HF is a rugged, high-performance device that features a high peak current rating, which make it suitable for applications with high amplitude current transients.

Application Fields:

The ACZRA4762-HF has a wide range of applications. It is an ideal choice for many types of electronic circuit designs, especially power supply regulation and voltage protection. The device can also be used in traditional applications such as temperature sensing. Additionally, it is also suitable for laser power supply control and switching applications in computers, motor control, lighting systems, automotive electronics, and instrumentation.

Working Principle:

Zener diodes work by conducting current in the reverse bias direction. When the voltage applied to the device exceeds a certain “breakdown voltage”, it quickly begins conduction and it will remain in the conducting state until the applied voltage drops below the breakdown voltage. This breakdown voltage is determined by the design of the Zener diode and doesn’t change with temperature or current. This breakdown voltage is also known as the Zener voltage and is the important factor that makes a Zener diode useful to control voltage.

The flow of current is not the same in both directions. When the voltage is below the breakdown threshold, the diode behaves as an ordinary diode and will not conduct much current. In contrast, when the voltage reaching the device exceeds the breakdown voltage, current begins to flow in the reverse direction in a process know as Zener Avalanche Breakdown. The amount of current that flows depends on the amount of voltage applied and the characteristics of the diode itself.

The ACZRA4762-HF can be used in applications where the current must be limited to a particular level. The device is able to handle high peak currents, making it suitable for applications with high amplitude current transients.

Conclusion:

The ACZRA4762-HF is an excellent Zener diode for voltage regulation and protection applications. It features high peak current ratings and low leakage current, making it suitable for a variety of applications, such as power supply regulation, temperature sensing, laser power supply control, switching applications in computers, motor control, lighting systems, automotive electronics, and instrumentation.
