Working Principle

The working principle of JANTX1N4979US consists of a reverse biased P-N junction. It works under a specific breakdown voltage, known as Zener Breakdown Voltage or Zener Voltage. This voltage is fixed and quite generally corresponds to the voltage at which the diode will breakdown.

In the reverse bias condition of the P-N Junction, the depletion region increases which leads to more recombination centers. This leads to more electrons reaching the conduction band and thus the diode starts conducting. However, the amount of current passing through the diode is limited by the external circuit. The current progressively increases as the applied voltage increases and exceeds the Zener breakdown voltage, and then stabilizes to hold the voltage constant at the zener breakdown voltage.

The Zener Voltage of JANTX1N4979US is 24 volts, which ensures that the output voltage remains constant after it reaches the breakdown voltage.

To summarize, JANTX1N4979US is a single Zener diode of type Zener diodes series, offering well-regulated and steady voltage regulation in commercial and industrial areas. It has great tolerance over temperature and other variations, an extremely low dynamic impedance, high reliability and it is perfect for a wide range of application such as AC-DC adaptors, telecom, industrial and HVAC equipment as well as flight applications.
