Diodes - Zener - Single: JANTXV1N4131C-1 Application Field and Working Principle

The JANTXV1N4131C-1 is a silicon planar, junction passivated, high power, voltage-regulating diode designed for applications requiring low-leakage (<1nA) high-voltage capability. Offering excellent low-leakage characteristics and stable, predictable zener-type operation with only 1.2V of zener voltage (Vz), the JANTXV1N4131C-1 is a popular choice for regulated power supplies.When integrated in a power supply, this diode can be used to maintain a desired output voltage with low voltage-drop across the zener diode. Thanks to its low-leakage design, the JANTXV1N4131C-1 is also suitable for high-voltage medical equipment and precision instrumentation applications. In this article, we will cover the application field and working principle of the JANTXV1N4131C-1 diode.

Application

The JANTXV1N4131C-1 is well-suited for power supplies and other applications requiring strict voltage regulation and/or low-leakage current. Typical applications include medical equipment, precision instrumentation, circuit protection, voltage regulation, and military/avionics equipment.

Working Principle

The JANTXV1N4131C-1 operates in a zener-type fashion, allowing voltage to be regulated through a reverse-biased diode. The diode can be controlled by adjusting the applied reverse-bias voltage. When a regulated output voltage is required, the diode is operated at its zener voltage (Vz), which is 1.2V for this specific diode.When reverse-biased, the voltage applied to the diode is greater than the zener voltage, thus producing the breakdown of the junction, resulting in a zener-type current flow. This zener current is limited by the ohmic resistance of the current-limiting resistor, resulting in a stable, regulated output voltage.

Conclusion

The JANTXV1N4131C-1 diode is designed for applications requiring low-leakage and high-voltage operation, such as circuit protection, precision instrumentation, and medical equipment. The diode operates in a zener-type fashion and maintains a regulated output voltage with only 1.2V of zener voltage.
