Diodes - Zener - Single

JANTX1N982CUR-1 is a single Zener diode, which is used to regulate voltage in a circuit. The Zener diode acts as a voltage regular and allows low level current to flow through it, while blocking higher level currents.

Application Field

The JANTX1N982CUR-1 is available in three different voltage ratings, 5.1V, 6.2V, and 7.5V, and the symbol UN is used to denote the rated voltage. The device has a power dissipation rating of 350mW, reverse voltage of 6V, and a maximum current rating of 200mA. It can operate between -65°C to 175°C.

JANTX1N982CUR-1 has a wide range of applications and can be used in high-grade audio systems, telecommunications systems, mobile phones, cellphone chargers, and security systems, among others. The device is also suitable for temperature compensation in oscillator circuits and for forming protective circuits. It is well-suited for high noise immunity and low power dissipation.

Working Principle

A Zener diode consists of a heavy doping of p-type and n-type semiconductors, which are connected through a junction. When the voltage applied across the junction is greater than the breakdown voltage, the Zener diode conducts and equalizes the voltage across the junction. When used to regulate voltage, the Zener diode usually placed in reverse bias, where its avalanche breakdown point acts as a fixed voltage reference.

When the voltage applied to a reverse biased Zener diode is lower than its breakdown voltage, current will not flow through it. However, if the voltage exceeds its breakdown voltage, the diode will conduct and adjust the voltage across the junction to its breakdown voltage. As a result, the diode will not allow any additional current to pass, which helps maintain the breakdown voltage or a preset voltage.

In addition, Zener diodes are used to protect sensitive electronics devices. This occurs when input voltage exceeds the breakdown voltage of the Zener diode, allowing the excess current to be diverted to the diode instead of damaging the device. This also prevents large transients from overwhelming the device.

Conclusion

The JANTX1N982CUR-1 is a single Zener diode from Microsemi Corporation, suitable for controlling reverse voltage and providing noise immunity. The device is available in three voltage ratings and has wide range of applications for high-grade audio systems, telecommunications systems, mobile phones, and security systems, among others.
