Bidirectional Zener diode 8. Application information High-voltage Zener diodes can be used as overvoltage protection diodes for Integrated Circuits (IC) due to their ability to cut off the applied voltage at a well-defined value. One important application is the protection of EL driver circuits where a driver IC is connected to an EL foil Zener Diode Explanation. A Zener Diode, also known as a breakdown diode, is a heavily doped semiconductor device that is designed to operate in the reverse direction. When the voltage across the terminals of a Zener diode is reversed and the potential reaches the Zener Voltage (knee voltage), the junction breaks down and the current flows in. Applications and Uses of Zener Diode can be seen in the following: As a voltage regulator. Protects from over voltage. Used in clipping circuits. Used to shift voltage. Due to the voltage drop across the diode remains constant over a wide range of voltages, Zener diode is suitable for voltage regulation Zener diode applications. Zener diodes are used for voltage regulation, as reference elements, surge suppressors, and in switching applications and clipper circuits. Voltage regulator. The load voltage equals breakdown voltage VZ of the diode. The series resistor limits the current through the diode and drops the excess voltage when the diode.

Zener Diode Properties The Zener diode is a unique device which exploits a property of diodes that is generally avoided in standard diode applications. Typical diodes have a very high reverse breakdown voltage, the voltage at which the diode begins to conduct in the reverse direction. This voltage is generally avoided in standard diodes, but. , A 6.8 V Zener diode exhibits a TC +2 mV/˚C, which is complementary to a forward biased diode! sometimes called Temco This leads to a popular strategy for compensating for the temperature dependence of Zener diodes depicted below: Here, the diode current is nearly independent of T (over a useful range of i)

The Zener Diode (blue trace, Vz) has a much sharper knee, steeper slope and tighter voltage tolerance (dashed lines and shaded region) than a TVS device. These differences come from design and optimization - the purpose of a Zener Diode is to provide an accurate voltage clamp within a signal circuit, or as a reference or regulator. A Zener.
