The 1N4982 is a specific type of diode within the larger family of Zener diodes. Zener diodes, also known as voltage regulators, are a type of semiconductor device which regulates an electrical current by allowing it to pass in a single direction and resist in an opposite direction. In other words, when AC electricity flows in one direction, the diode will block it from flowing in the opposite direction. This is beneficial in certain types of circuits that require a steady voltage.

The 1N4982 diode is specifically designed and engineered to rreegulate voltage by utilizing a specially designed Zener breakdown phenomenon that enables this Zener diode to have a higher breakdown voltage in comparison to other devices. This breakdown occurs when the applied voltage, also known as the Zener voltage, exceeds a certain threshold. The 1N4982 diode has a guaranteed Zener voltage range between 9.2 to 11.7 Volts which gives this device its unique capability of being able to maintain a stable, predetermined voltage level.

Beyond simple voltage regulation, the 1N4982 diode also includes numerous other characteristics such as reverse current, dynamic resistance, and avalanche. The reverse current is the amount of current in an opposite direction, the avalanche is the trigger voltage for the diode breakdown, and the dynamic resistance is the diode resistance in the region of breakdown. Specifically, this diode has a reverse current of 50 nano-Amperes (nA), an avalanche voltage at 10 mA of 5.70 volts, and a dynamic resistance of 15 ohms with a 5 volt variance.

One of the key features of the 1N4982 Zener diode is the design of its energy consumption, making it ideal for small electronics and devices. This particular diode has an energy consumption rating of 175 milliwatts, making it an ideal choice for applications where energy consumption is a key factor. The device also has a wide range of operating temperatures, ranging from -65°C - 150°C.

Several other properties make the 1N4982 an ideal choice for a variety of applications. One is the low capacitance which makes it an ideal solution for high frequency applications. Additionally, the device has a low leakage current which is beneficial for the stability of the device. As a matter of fact, this diode has one of the lowest leakage currents when compared to other similar diodes, enhancing its functioning capabilities.

The 1N4982 diode is an ideal choice for a variety of applications due to its versatility and performance. It is a great solution for voltage regulation in a range of audio and video equipment, such as amplifiers and video processors, as well as medical, military, and aerospace applications. Aside from simply controlling the flow of current, this Zener diode also eliminates oscillations with its low-capacitance properties.

In summary, the 1N4982 diode is a highly-versatile diode primarily used for voltage regulation in electronic circuits. The device includes characteristics such as reverse current, dynamic resistance, avalanche, low capacitance and leakage current, and a wide range of operating temperatures. It can be used in a variety of applications such as audio and video equipment, medical, military, and aerospace equipment, and for eliminating oscillations.
