JAN1N4132C-1

JAN1N4132C-1 Application Field and Working Principle

The JAN1N4132C-1 is a single Zener diode. Specifically, this device is a voltage regulator that is made from a lightly-doped p-n junction of silicon. Zener diodes are used as voltage regulators in electronic circuits that require very low power or to stabilize power supply lines. The JAN1N4132C-1 can function at a current up to 350 milliamps (mA), and it features a reverse breakdown voltage of 8.2 volts (V).

How Zener Diodes Work

At voltages below their specified reverse breakdown voltage, Zener diodes behave just like regular diodes. In this reverse bias mode, the majority charges on the donor side of the junction are surrounded by the majority charges on the acceptor side, thus forming a very thin depletion region. This depletion region acts as an insulating barrier between the two sides of the junction, preventing any current from flowing through the diode.However, when the reverse bias voltage applied across the diode becomes greater than the specified breakdown voltage, a state known as reverse breakdown occurs. In this state, the depletion region is restructured so that electrons on the donor side can easily flow across the junction and combine with holes on the acceptor side. This flow of electrons creates a current in the reverse direction, and the resulting voltage across the junction remains relatively stable, near the specified breakdown voltage.

Applications of the JAN1N4132C-1

Given its excellent reversing breakdown characteristics and low power requirements, the JAN1N4132C-1 is an ideal voltage regulator for a wide variety of applications. These include DC-DC voltage regulation, power supply regulation and voltage doubling, providing a stable voltage output with minimal power losses. It can also be used for over- and under-voltage protection circuits to protect sensitive components from sudden voltage spikes.

Conclusion

The JAN1N4132C-1 Zener diode is an efficient voltage regulator that is well-suited for low-power applications. Its low power requirement and robust, consistent reverse breakdown voltage makes it an ideal choice for power supply, voltage regulation and over/under-voltage protection.
