TZX18C-TR

Diodes - Zener - Single

The TZX18C-TR is a Zener diode specifically designed for voltage reference applications. It has the ability to provide a stable voltage when the current varies over a wide range. This type of diode plays an important role in the operation of logic circuits and various other electronic devices, and is widely used in many industrial automation applications.

Working Principle

The TZX18C-TR is a two-terminal device that operates on an internal breakdown voltage. As the voltage across its two terminals exceeds this breakdown voltage, current begins to flow through it in the reverse direction. This phenomenon is known as reverse breakdown. The current flow increases exponentially with the applied voltage until the diode reaches a maximum current rating.

When the current flows in the reverse direction, it is called the reverse bias current. Its current-limiting properties prevent the device from exceeding the maximum current. This current-limiting property helps prevent it from heating up and collapsing due to excessive current. As the reverse bias current is limited, a certain voltage develops across the device, independent of the applied voltage. This voltage is of the desired magnitude and is used for reference purposes in a circuit.
