Introduction

The DFLZ10-7 is a Zener diode, commonly used for voltage regulation and voltage protection applications. It is a single-package device that features a two-terminal reverse-biased breakdown operating region. The DFLZ10-7 is unique in that it contains an integrated Junction Temperature Regulator (JTR) that allows for precise control of the breakdown voltage for applications over a wide temperature range.

Application

The DFLZ10-7 is typically used as a voltage regulator and voltage protector. It offers very precise breakdown voltage control, as well as temperature compensation, making it ideal for use in a wide range of applications across many different industries. The most common applications for the DFLZ10-7 include voltage regulation for power supplies, electronic current switches, AC/DC adaptors, motor controls and converters. Additionally, the DFLZ10-7 is well-suited for power offset, buffer integration and signal conditioning applications.

Working Principle

The DFLZ10-7 is a two-terminal device that operates on the principle of reverse biased breakdown. When the applied voltage exceeds a predetermined value, the voltage-drop or breakdown voltage, the internal resistance of the device rapidly decreases. This causes a current to flow from anode to cathode, and the diode adjusts its breakdown voltage in an attempt to maintain a constant voltage drop. In order for the DFLZ10-7 to maintain its temperature compensation, the Integrated Junction Temperature Regulator (JTR) allows the diode to adjust its breakdown voltage with changes in ambient temperature. The breakdown voltage is then kept within a range of ±1% over a wide temperature range.In addition to keeping the breakdown voltage within a specified range, the DFLZ10-7 is also capable of blocking current output. This is known as the “Clip” effect and occurs when the diode is biased in the reverse breakdown region in a manner that a secondary current is limited to a safety level. This feature makes it ideal for use in applications where electrical shorts or malfunctions could otherwise cause a significant amount of damage.

Conclusion

The DFLZ10-7 is a two-terminal Zener diode that offers a great level of precision and temperature-compensation in its breakdown voltage performance, making it suitable for a broad range of voltage regulation and voltage protection applications across different industries. This diode is equipped with the integrated Junction Temperature Regulator (JTR) that allows it to adjust the breakdown voltage according to temperature changes and also block current output in the event of any malfunctions.
