• Over-voltage protection
• Voltage stabilization
• Ringing chokes

The JANTXV1N3826AUR-1 is mainly used in automotive and consumer electronics due to its excellent light tolerance and thermal-mechanical stability. It is also used in LED lighting and communication systems.

Working Principle

When the anode of the diode is at a positive voltage, then holes and electrons are injected into the junction. This results in the formation of a depletion layer in the junction which keeps the electrons and holes from recombining. This phenomenon makes the diode to act as an insulating material in forward bias.

When the Zener diode is reverse biased, then the depleted region depth increases, which results in a wide bandgap in the junction. This is because the role of the Zener voltage changes due to the flow of heavy current. When a voltage is applied to the junction, it reaches the Zener voltage level and enables the current to flow during the breakdown. This is known as the Zener tunneling effect and it results in the diode exhibiting a linear voltage-current characteristics.

As the name suggests, the JANTXV1N3826AUR-1 is a Zener diode which produces an output voltage that remains linear over a very wide range of currents. This makes it ideal for use in power supplies and voltage regulators that require a stable output voltage. The Zener process allows the component to maintain a relatively low temperature even at high current loads.

Conclusion

The JANTXV1N3826AUR-1 is a high stability and wide temperature range Zener diode with a voltage rating of 3.3V, a Zener current of 500 mW, and a voltage reverse current of 500 nA. It is typically used in applications that require linear regulation of power, such as regulated DC power supplies, automatic protection circuits, and voltage limiting and clipper circuits. This component also has excellent light and thermal-mechanical stability, making it suitable for use in automotive, lighting, communication system, and consumer electronics applications.
