Introduction

The JANTX1N4971CUS is a surface mount Zenner-type diode, offering low leakage current and highly reliable performance in surface mount applications. It offers excellent electrical characteristics, including good reverse polarity protection and reverse voltage capability. Additionally, the JANTX1N4971CUS offers a higher power rating than other Zenner-type diodes in a similar package size.

ApplicationFields

JANTX1N4971CUS is suitable for device protection circuits, voltage level shifters, power management, and ESD protection circuits as well as for automotive applications. It can also be used for general purpose switching, interference suppression, and signal level shifting. The diode also provides superior noise immunity and dead-time protection from transients in power supply lines and circuit protection applications.

Working Principle

Zenner-type diodes are used mainly to control voltage. They are designed to have a very specific breakdown voltage that is known as the Zener voltage. When this Zener voltage is reached, a large amount of current will start to flow through the diode, creating a voltage droop that limited to the Zener voltage, thus controlling the voltage. The JANTX1N4971CUS is constructed with a reversed recovery time so that the diode can respond quickly to transient signals in order to provide superior noise immunity and dead-time protection.The diode can also be used in other applications such as AC/DC conversion, buck-boost converters, DC/DC converters, and voltage regulation.

Conclusion

The JANTX1N4971CUS is a surface mount Zenner-type diode with a higher power rating than other Zenner-type diodes in a similar package size. It offers excellent electrical characteristics with low leakage current and reliable performance in surface mount applications. The diode is suitable for device protection circuits, voltage level shifters, power management, and ESD protection circuits. It can also be used for general purpose switching, interference suppression, and signal level shifting as well as AC/DC conversion, buck-boost converters, DC/DC converters, and voltage regulation.
