It is also suitable for the regulation of load with low dropout voltage and high current. It is especially suitable for circuitry with high peak current, ultra-high dynamic response, and high frequency, where the ACZRA4738-HF diode has an advantage over other options.

Working Principle

The ACZRA4738-HF diode is a single Zener diode. It utilizes the Zener effect, which is a reversible breakdown effect that occurs when the voltage across a PN junction exceeds a certain value known as the Zener voltage. When the reverse bias voltage increases beyond the Zener voltage, carriers of opposite type generated in the depletion layer are accelerated from the P and the N sides of the diode towards the junction until they meet, resulting in the conduction of current and the regulation of voltage. The ACZRA4738-HF diode is programmable, meaning that the Zener voltage can be set to a desired value.

Conclusion

In conclusion, the ACZRA4738-HF diode is a single Zener diode with a wide application field and great performance. It is a perfect choice for DC to DC conversion, high peak current, ultra-high dynamic response, and high frequency circuits. Utilizing the Zener effect, it is capable of protecting existing circuits from reverse bias voltages, and its programmable element allows for setting the Zener voltage as required.
