Diodes - Zener - Single

The 1N4480US is one of the most popular and widely used Zener diode. Zener diodes are essential components used in countless electronic devices, from power supplies and voltage regulators to signal clampers and voltage multipliers -- in essence, any circuit which requires a steady, predictable voltage level. The unique properties of Zener diodes make them the go-to electronic component in applications which require a controlled voltage reference.

Structure

The 1N4480US is a three-layer diode that\'s m ade up of p-type and n-type layers sandwiched together. One of the terminal outputs is connected to the p-type layer and the other terminal output is connected to the n-type layer. This arrangement is referred to as a p-n junction.The junction between the p-type and n-type layers, or PN junction, forms the actual diode.

Working Principle

The Zener diode\'s working principle is very simple. The diode operates in the reverse breakdown condition when the voltage exceeds a certain level. When the diode is in the reverse breakdown condition, electrons start to flow from n-type to p-type layer. This flow of electrons results in a voltage drop across the diode. This voltage drop is called the Zener voltage.

When the voltage exceeds the Zener voltage, current starts to flow through the diode. This current is the result of the flow of electrons from the p-type layer to the n-type layer. This current is called Zener current. In order to maintain a constant Zener voltage, Zener current must be maintained at a constant level. This is due to the fact that Zener diode has negative temperature coefficient.

Application Fields

The 1N4480US are commonly used in applications where a precise and stable voltage is required. Such applications are oscillators and regulators for small digital circuits, LED LED LED LED LED LED LED LED LED lighting systems, and power supplies.
