Diodes are a type of semiconductor devices that allow current to flow in only one direction. Zener diodes are specialized diodes, which regulate voltage in a circuit. JANTXV1N974DUR-1 is a type of Zener diode designed to feature a high-voltage breakdown, small size, and excellent temperature stability. In this article, we are going to take a look at the application field and working principle of JANTXV1N974DUR-1.

Application Field

The JANTXV1N974DUR-1 Zener diode is specifically designed for microprocessor- and logic-device protection that requires high-voltage breakdown and very small size. With a maximum rated power of 450 mW, the JANTXV1N974DUR-1 is suitable for low-current, high-voltage applications. It can effectively regulate voltages in circuits that require stable, low-ripple voltages over wide temperature ranges. The JANTXV1N974DUR-1 can also be used in DC-to-DC converters, voltage-clamping applications, overvoltage protection, and circuit protection.

Working Principle

The JANTXV1N974DUR-1 operates by maintaining a constant voltage across its terminals regardless of the current running through the device. When the circuit is connected to a source, the diode behaves like an open circuit in the forward direction (from anode to cathode positive), and the voltage across it remains essentially at zero. When the voltage applied between the anode and cathode exceeds the forward breakover voltage, current starts to flow in the forward direction. This voltage is known as the Zener voltage, and it is the voltage at which the current through the device is equal to the maximum specified current for the device. Above the Zener voltage, the voltage across the diode remains essentially constant regardless of the applied current.

In the reverse direction, the JANTXV1N974DUR-1 exhibits a low reverse leakage. This ensures that the breakdown voltage of the diode remains within specified limits regardless of the temperature. The diode\'s resistance also remains relatively low, since it is dependent on the current flowing through the device. This allows the JANTXV1N974DUR-1 to remain stable over a wide range of temperatures and be used in applications that require precise regulation of the input or output voltage.

Conclusion

To summarize, JANTXV1N974DUR-1 is a type of Zener diode designed for microprocessor- and logic-device protection that requires high-voltage breakdown and very small size. The diode features a high-voltage breakdown and excellent temperature stability, and is suitable for low-current, high-voltage applications. It can be used in DC-to-DC converters, voltage-clamping applications, overvoltage protection, and circuit protection. The diode works by maintaining a constant voltage across its terminals regardless of the current running through the device, thus allowing for precise voltage regulation.
