Working Principle

The JANTXV1N5524CUR-1 is a silicon planar epitaxial Zener diode. Its conduction is the result of a combination of two mechanisms – avalanche breakdown and Zener breakdown. In avalanche breakdown, when the diode is reverse biased, the PN junction becomes weaker and electrons quickly accelerate across the junction. As the electron velocity increases, an avalanche of charge carriers is created, resulting in conduction of current through the junction. Zener breakdown occurs when a Zener junction is reverse biased. When the voltage across the junction reaches a certain level, the high electric field causes electrons to be emitted from the N-type material at the junction and injected into the P-type material, allowing current to flow through the junction. The JANTXV1N5524CUR-1 has a breakdown voltage of 5.5 Volts.

In its normal operation, the JANTXV1N5524CUR-1 conducts current in one direction only, from anode to cathode. In this way, it can be used to serve as a voltage regulator or voltage reference. When the voltage across the diode reaches its Zener voltage, the current through the diode decreases drastically, preventing any further increase in the applied voltage. This helps to provide a stable voltage across the diode, even in the presence of voltage fluctuations.

The JANTXV1N5524CUR-1 is designed to operate over a wide temperature range of -55°C to +125°C and can withstand a maximum reverse voltage of 5.5 Volts. It also features a tight tolerance of ±3% for Zener Voltage and ±1.5% for Maximum Forward Voltage.
