Diodes - Zener - Single

The GLL4758A-E3/97 is an example of a single Zener diode, a diode specifically designed for voltage regulation and voltage stabilization. This diode is designed to provide extremely accurate reference voltages and maintains its other operating characteristics over the long-term and is widely used in the control circuitry of many different devices.

Application Field

Single Zener diodes are designed to regulate or stabilize the flow of current and voltage. This type of diode is ideal for Voltage Regulation and Noise Suppression, so it is often used in the control circuitry of integrated circuits, amplifiers, or any device that needs a steady, reliable voltage source. Additionally, this diode is also designed to limit current to a safe level in the event of an overvoltage.

Working Principle

The working principle of the single Zener diode can be explained by looking at its construction. The diode is divided into two sections, the p-type section and the n-type section. A small forward current is applied to the diode, which causes a depletion region to form at the junction of the two sections, creating a special type of tunnel diode. This depletion region creates a barrier which allows a certain level of voltage to pass through. When the forward voltage applied to the diode reaches a certain predetermined voltage, known as the Zener voltage, the conduction of current increases significantly. The Zener region acts to regulate the current, eliminating fluctuations and thus stabilizing the voltage at its predetermined level.

In conclusion, the GLL4758A-E3/97 single Zener diode is an essential component for maintaining a steady output voltage. By regulating the forward current and stabilizing the output voltage, the single Zener diode is the key component for many of today\'s electronic devices.
