JANTX1N4125DUR-1

Diodes - Zener - Single

JANTX1N4125DUR-1 is a single-element zinc oxide varistor. It is a disc-shaped device constructed from a homogeneously solated material pressed into a can-shaped structure. The features of JANTX1N4125DUR-1 are high electrical endurance, high repetitive rate, and high surge current capability.

The primary application areas of JANTX1N4125DUR-1 include transient protection, noise reduction, circuit isolation, and regulator bypass. It is an excellent solution for suppressing transients and EMI/RFI interference in communication and power systems.

Working Principle

JANTX1N4125DUR-1 is a zener diode, which facilitates the flow of current in one direction. When an external voltage is applied to the device, at a predetermined value it induces an avalanche breakdown in the P-N junction of the device. This breakdown is caused by electrons having sufficient energy to cross the junction barrier, and when this happens, a voltage drop will occur across the device.

This breakdown enables the current to flow from the anode to the cathode in the reverse bias and allows a sizable current to be conducted in both the forward and reverse bias. The voltage clamping provided by JANTX1N4125DUR-1 is based on the zener voltage. The Zener voltage is the voltage at which the avalanche breakdown occurs and is determined by the characteristics of the material used in the construction of the device.

The device also enables the current to reverse bias to the anode side. The current will flow from the anode to the cathode, and back from the cathode to the anode along the same resistance. This circuit is known as a Zener diode, and the voltage clamping it provides is based on the Zener voltage.

The Zener voltage is determined by the characteristics of the material used in the construction of the diode, and the current will be limited to the current rating of the diode. In addition to the voltage clamping, JANTX1N4125DUR-1 also provides isolation from transient disturbances, noise reduction, and other advantages offered by other types of varistors.

Conclusion

JANTX1N4125DUR-1 is a single-element zinc oxide varistor which is the ideal choice for transient protection and noise reduction in communication and power systems. It utilizes a Zener diode to provide clamping action at a predetermined voltage. The Zener voltage of the diode is determined by the characteristics of the material used in the construction of the device and the current will be limited to the current rating of the diode.
