JANTX1N4122UR-1

Diodes - Zener - Single

JANTX1N4122UR-1 is a single Zener diode manufactured by Microsemi Corporation. It is designed for low-power voltage stabilization applications. The device is equipped with a wide forward current range and provides a full suite of protection characteristics for circuit protection. The diode is constructed using planar technology and utilizes a self-aligned N-diffusion layer for improved doping and low operating power dissipation.

Application Field of JANTX1N4122UR-1

The low power dissipation and wide forward current range of the JANTX1N4122UR-1 makes it suitable for use in voltage regulation circuits. It is especially well-suited for applications that require a voltage drop of between 0.5 and 1.5V and in circuits that can provide a continuous forward current of 500mA or less. The device can also be used in a wide range of circuit protection applications, such as surge, over-voltage, and short circuit protection.

Working Principle of JANTX1N4122UR-1

The forward voltage of a Zener diode, like the JANTX1N4122UR-1, is typically independent of the amount of current through it, meaning it will have a much lower forward voltage drop than other types of diodes. This allows the device to serve as a regulator, maintaining a constant output regardless of changes in input. The device works best when operated in the avalanche breakdown region, where it will convert excess voltage into heat and dissipate it. This ensures that the output voltage stays within the specified limits.

Benefits and Limitations of JANTX1N4122UR-1

One of the main benefits of the JANTX1N4122UR-1 is its low power dissipation, which makes it an ideal choice for low-power voltage stabilization applications. It is also resistant to electrical field and static shock, protecting it from damage in high-voltage environments. The device also features a built-in short circuit protection, ensuring that it is not damaged by excessive current.

However, this device is not suitable for use in applications with higher current levels. It is also susceptible to thermal drift, which limits its accuracy. Additionally, the device should be kept away from moisture and corrosive environments to ensure proper operation.
