Diodes - Zener - Single

DZ2J39000L is a high-precision, single zener diode. It is specially designed to provide exceptionally high regulator accuracy and power dissipation for use in commercial, industrial, and consumer applications.

Application Field

DZ2J39000L is used in a wide range of applications, such as voltage reference and voltage voltage regulation. It can be used as a voltage regulator in power supplies, voltage-level shifting, voltage-level clamping, overvoltage/reverse polarity protection, and other related applications.

It is also used model trimming in radio frequency circuits, wireless systems, and consumer electronic applications.

Working Principle

DZ2J39000L works based on the Zener breakdown phenomenon. Zener breakdown occurs when a reverse-biased voltage is applied across a Zener diode, and a breakdown current flows. The reverse breakdown voltage is determined by the Zener diode’s geometry, doping level, and method of manufacture.

When the voltage across the DZ2J39000L reaches the Zener breakdown voltage (which is usually nominally around 3.9 V), the voltage remains approximately constant, no matter how much current is drawn. This makes it suitable for applications where a precise voltage reference is needed.

The Zener diode also has a maximum power rating, which limits the maximum current that can be drawn from the diode. Exceeding the maximum power can result in the diode failing, so it is important to design circuits around the DZ2J39000L appropriately.
