Diodes - Zener - Single

JANTX1N4129UR-1 is a 28-volt 5.1-watt Zener diode that finds extensive applications in markets such as industrial, military and automotive. This diode is intended for use in applications such as clippers, clampers and voltage-regulator circuits and offers outstanding performance, high reliability and excellent electrical characteristics.

JANTX1N4129UR-1 is designed to operate over a wide range of temperatures ranging from -65℃ up to 175℃. It also comes with built-in protection against electrical transient disturbances which helps to ensure its reliable performance in computer-driven circuits and other critical applications.

The JANTX1N4129UR-1 is a single low-power Zener diode with an extremely small power dissipation rating. It is the perfect solution for radiation-hardened applications, where compact size and low profile of the device are important. It also features a low-noise operation and high-efficiency properties.

The working principle of a Zener diode is based on two basic principles: the first principle is that when a reverse voltage is applied to the diode, a narrow depletion layer (also known as a depletion region or depletion zone) forms and the second principle, which is that the junction between the semiconductor material and anode of the Zener diode acts as an energy barrier. The voltage applied to the diode causes electrons and holes to cross the barrier and reduces the internal energy of the junction. This causes a change in the electrical properties of the diode and allows current to flow in the reverse direction.

The JANTX1N4129UR-1 is employed in a wide range of applications such as switching, clipping and clapping, voltage regulation and voltage-limiting in order to protect sensitive components from voltage spikes.

The Zener diode is traditionally used in power supplies and linear regulators, acting as the main dissipator of negative voltage spikes. The JANTX1N4129UR-1 is designed specifically to cope with negative voltage spikes, eliminating the need for expensive and bulky solutions like protection diodes or protection circuits.

The JANTX1N4129UR-1 is also used in a variety of voltage-limiting applications and provides an economical, low-noise, and high-efficiency solution for these applications. It offers greater efficiency when compared to other diodes in the same power range, due to its minimal power loss owing to its low-voltage operation.

In conclusion, the JANTX1N4129UR-1 is an ideal solution for many common applications, including: low-current switching, clipping, clamping, voltage regulation, and voltage-limiting. Its wide operating temperature range and built-in protection against transient disturbances ensures reliable performance even under extreme environmental conditions. The Zener diode, with its working principle based on the two basic principles of a reversed voltage and the energy barrier, provides an efficient and economical voltage-limiting solution, while eliminating the need for expensive and bulky components.
