Single Zener Diodes

A single Zener diode, such as TZM5244C-GS18, is a component used to regulate and control the voltage levels in electrical circuits. It is a form of ‘low dynamic resistance’ diode primarily designed for voltage regulation.

Application Fields

A single Zener diode, such as TZM5244C-GS18, is used in many application fields, including power supply applications, regulated power supplies, transient suppression, ESD protection and circuit protection.

TZM5244C-GS18 is also suitable for use in industrial and consumer electronics, medical applications, instrumentation and automotive electronics.

Thanks to its wide operating temperature range of -55°C to 175°C, this component is highly effective in numerous temperature-sensitive or high-temperature applications.

Working Principle

A single Zener diode is a semiconductor component composed of two regions, i.e., the ‘p-type’ and ‘n-type’ regions. The p-type region, which consists of positive charge carriers referred to as ‘holes’, is closest to the anode, i.e., for TZM5244C-GS18, it is on the striped side of the component. The n-type region, which consists of negative charged particles referred to as ‘electrons’, is closest to the cathode, i.e., on the unmarked side of the component.

The working principle of a single Zener diode is based on the fact that, when a certain voltage across its two terminals, called the ‘Zener breakdown voltage’ is reached, an avalanche current flows in the opposite direction to the diode’s normal direction of current.

For TZM5244C-GS18, the Zener breakdown voltage is approximately 4.7V. This means that when a voltage of 4.7V or greater is imposed across this component, the Zener-favorable current will flow from the anode to the cathode, allowing voltage regulation in the circuit.

Single Zener diodes, such as TZM5244C-GS18, are widely used in applications that require voltage stabilization and protection against unwanted transients, such as in power supplies and in automotive electronics, thanks to their high durability and stable performance.
