For example, a diode with a Zener breakdown voltage of 3.2 V exhibits a voltage drop of very nearly 3.2 V across a wide range of reverse currents. The Zener diode is therefore well suited for applications such as the generation of a reference voltage (e.g. for an amplifier stage), or as a voltage stabilizer for low-current applications. [2]
The diode is made in axial-lead DO-35 glass package. [1] Regulating voltages varies from 2.4 V to 75 V with a total power dissipation maximum of 500 mW. In some datasheets, the series is labelled as zener diode , [ 2 ] but this is not always the case as the series relies on avalanche breakdown for higher voltage.
The LTZ1000 is a high-precision, ultra-stable Zener diode voltage reference originally developed by Carl Nelson for Linear Technology (now Analog Devices). It consists of a Zener reference packaged along with an integrated heater and temperature sensor designed to hold the device at a constant temperature for improved stability. [1] [2]
These diodes can indefinitely sustain a moderate level of current during breakdown. The voltage at which the breakdown occurs is called the breakdown voltage . There is a hysteresis effect; once avalanche breakdown has occurred, the material will continue to conduct even if the voltage across it drops below the breakdown voltage.
In electronics, the Zener effect (employed most notably in the appropriately named Zener diode) is a type of electrical breakdown, discovered by Clarence Melvin Zener. It occurs in a reverse biased p-n diode when the electric field enables tunneling of electrons from the valence to the conduction band of a semiconductor , leading to numerous ...
Zener diode based noise source. A noise generator is a circuit that produces electrical noise (i.e., a random signal). Noise generators are used to test signals for measuring noise figure, frequency response, and other parameters.
