Diodes come in many different shapes and sizes, and they are used in numerous astounding applications. One such diode is the JAN1N4967D (also known as a 1N4749A), which is a zener diode with a single junction. It is primarily used in regulating and/or buffering voltage to limit current as well as for over-voltage protection.

The JAN1N4967D is an addition to the very well known family of 1N4148 silicon diodes. This diode has a reverse breakdown voltage of 4.7 volts, and it has a high power rating of 500 mW (with respect to 125°C). This diode has a maximum continuous forward current of 500 mA and a maximum forward voltage drop of 1.1V.

This diode is commonly used in automatic sets, where it can help protect the TV sets from being damaged due to over-voltage caused by lightning and other voltage spikes. When used in sets, the JAN1N4967D will protect the sets from these hazardous power spikes and prevent damage to the electrical components.

The JAN1N4967D also finds use in circuitry related to personal electronics, when the capacity needs to be limited, but the voltage needs to remain consistent. This is why the diode is often used in cell phones, tablets, portable computers and other mobile devices. The device is small and convenient, yet can handle a fairly high current and is highly reliable.

In terms of its working principle, the JAN1N4967D follows the principle of a diode\'s junction voltage drop, which is the voltage drop through the diode, when it is forward biased. If a voltage is applied to the diode\'s anode (positive) side, and it is higher than the forward voltage of the diode, an electric current will flow through the device. This electric current is limited, depending on the power rating of the diode, thus protecting the other device from being damaged.

At the same time, when the voltage is applied to the reverse side (negative) of the diode, the voltage drop decreases and the electric current that flows through it is also limited. This is to prevent over-voltage and over-current from reaching the other device, thus protecting it from being damaged.

The JAN1N4967D is thus useful and important in protecting other devices from over-voltage and over-current and it is usually easy to find and inexpensive to buy. It is also highly reliable and has a high power rating and a low reverse breakdown voltage, making it an ideal choice for many applications, including personal electronics and automatic sets.
