Working Principle

The JANTX1N2982B is a single Zener diode device based on the principle of avalanche breakdown, featuring a very low operating and reverse breakdown voltages. When forward biased, the junction region of the device will experience a decrease of potential barrier size due to the avalanche breakdown. The current then flows from the anode to the cathode of the diode, allowing the transfer of the potential variation from one junction to the other.

When the diode is reverse biased, the PN junction is formed and the potential barrier increases. The current then cannot flow from the anode to the cathode and instead will stay within the junction region. In this situation, the electrical energy stored in the junction region will reach a point where the avalanche breakdown occurs, resulting in a significant portion of the current being dissipated as heat.

The Zener breakdown is the property of the JANTX1N2982B device that makes it suitable for overvoltage protection and lightning protection. When the voltage at the diode exceeds the Zener voltage, a large amount of current will be quickly released from the device, thus protecting any component connected behind the diode.
