The 1N2814A is a type of diode that is part of the Zener family and classified as single. It is specially designed to function within variety of applications, notably in circuits where it is used as a protective or stabilizing element. Particularly, the main purpose of the 1N2814A is voltage regulation.

The 1N2814A features a silicon planar based junction with a broader voltage range compared to its 2N1305 and 2N1307 counterparts. It is characterized by an operating temperature range of -55°C to +200°C and its mechanical data rating is between 28 and 69 mW. Although voltage operating range is of 6.2 to 83 volts, its peak power dissipation is often at a fixed level sufficiently above this range hence allowing its use as a protective device where overvoltage may occur. Other particularities of the diode include a maximum working voltage of 73 volts, a nominal zener voltage between 6 and 8 volts and a tolerance of 5 percent.

In terms of its working principle, the 1N2814A acts in the following way: Once a current of 10 milliamperes is passed through it, it gets to the point of coefficient breakdown. This initiates the Zener effect, which has the purpose of keeping the total voltage constant despite changes in the voltage of the incoming power line. This happens due to the fact that once the voltage reaches the diode breakdown voltage, an avalanche of electrons quickly produces enough current to provide a base level of voltage stability and regulation. This also notably allows the 1N2814A to regulate the voltage found preceding it at the same level as its own.

Due to its particular characteristics, the 1N2814A diode is used within central heating, control and instrumentation, industrial, audio and other industrial and consumer applications. Such use includes things such as voltage regulation of power supplies, frequency multiplier, ripple suppression, polarity protection, and other actuation applications.

Moreover, the 1N2814A can also act as a voltage reference, since it maintains a consistent voltage once the Zener affect takes place in it. This makes the 1N2814A suitable for a number of reference applications such as linear regulators or stabilized supplies.

The 1N2814A diode type conforms to standard military specifications and can be used in almost any application as long as it is operated within its working parameters, which allow for a wide range of operation. Commonly, 1N2814A zeners are mounted in series and connected to a regular voltage source, allowing the 1N2814A to be used as a voltage shunt regulator.
