Introduction

JANTXV1N747CUR-1 belongs to the Diodes - Zener - Single category. It is a single silicon Zener diode in a two-lead low-profile surface mount (SOD-123) package. This device provides very cost-effective solutions for Zener voltage regulation in low-current applications.

Application Field

This product is mainly used in high-frequency rectifiers, voltage regulation, voltage reference, reverse protection, communication circuits, etc. It has the advantages of high stability, low leakage current, and fast switching speed. This product is also suitable for use in various radio communications, consumer electronics, and various other devices which demand Zener voltage regulation.

Working Principle

JANTXV1N747CUR-1 is a Zener diode, which works when it is connected in reverse bias. In a reverse bias circuit, the p-type layers of the diode are mainly connected to the anode and the n-type layers are connected to cathode. As a result, the applied voltage at the diode will be concentrating on the p-n junction of the diode and causes high electric field across the junction. As a result, the majority carriers, electrons and holes, will be accelerated to recombine at the junction. When the majority carriers recombines, a small amount of energy will be released, thus introducing a Zener voltage across the diode.

When no current flows in the circuit, the Zener voltage across the diode remains constant until the applied voltage is greater than the maximum breakdown voltage (typically 6-56V). When the required voltage across the diode exceeds the Zener voltage, the Zener diode will start to conduct current and thus maintaining the required voltage across the diode to the breakdown voltage.

Conclusion

JANTXV1N747CUR-1 is a single silicon Zener diode in a two-lead low-profile surface mount package. It is mainly used for high-frequency rectifiers and voltage regulation in low-current applications. It works by breaking down the p-n junction and maintaining a constant Zener voltage across the diode.
