Diodes, also known as semi-conductors, are electronic devices that are used to direct the flow of electric current. A single diode, such as the JAN1N4975C Zener diode, is designed to control the flow of electric current through a single junction, redirecting the flow when necessary. This article will discuss the application field and working principle of the JAN1N4975C Zener diode.

The JAN1N4975C is a single Zener diode with a maximum low current rating of 0.5mA, a maximum high current rating of 15mA, and a maximum power rating of 500mW and a breakdown voltage of 4.7V. The Zener diode is a special type of diode that allows the current to flow both ways, and the reverse breakdown voltage allows the current to move in the opposite direction. This process is called “clamping”, and it allows the voltage to stay at a certain level, regardless of the current, thus acting as a voltage regulator.

The JAN1N4975C Zener diode is most commonly used in handheld power sources, such as mobile phones and other portable devices, as a voltage regulator to maintain stable voltage, even when the current fluctuates, thus protecting the electronic device from damage. The JAN1N4975C Zener diode is also used in television sets, computer monitors, and other home entertainment systems as a voltage regulator.

The JAN1N4975C Zener diode is characterized by its V-I curves, which show the relationship between the Voltage and Current. The V-I curve shows three regions of operation; the forward-biased region, the reverse-biased region, and the breakdown region. In the forward-biased region, current flows from anode to cathode, whereas in the reverse-biased region, current flows from cathode to anode. In the breakdown region, the voltage can drop to near zero and the current can be significantly higher than in the forward-biased region. This is what is known as the “clamping” effect, and this is what makes the JAN1N4975C Zener diode so effective as a voltage regulator.

In summary, the JAN1N4975C Zener diode is a single-junction diode designed to regulate voltage and protect devices from damage. The JAN1N4975C has a maximum low current rating of 0.5mA and a maximum high current rating of 15mA, with a maximum power rating of 500mW. Its V-I curve shows three regions of operation: forward-biased, reverse-biased, and breakdown, and it is most commonly used in handheld power sources, television sets, and computer monitors.
