Diodes - Zener - Single is one type of many different categories of semiconductor diodes. The patented KDZVTR8.2B part is a special application example of this type commanding great interest from electrical enthusiasts and hobbyists because of its unique qualities and abilities. This article provides a comprehensive overview of this part, beginning with its application field and ending with its working principle.

Application Field and Purpose

A KDZVTR8.2B is a Zener Diode designed to be used in many different types of AC/DC circuits as a voltage regulator with high reliability. This diode can be used as a protection device in high power switching applications and is particularly suitable for high frequency, high power applications. It is designed to protect equipment and components from damage by limiting the voltage within the circuit. It can also be used to provide stable voltage for systems which need a steady stream of power.

Materials and Specifications

The KDZVTR8.2B is a single-terminal type diode made up of a semiconductor material. It is available in a variety of sub-types, each slightly different in terms of its breakdown voltage, peak current and surge current ratings. It is built to be used in a variety of voltage levels and under a variety of temperature ranges. Its package type is an isolated metal case with 8 mm of pitch.

The rated breakdown voltage (also known as its Zener voltage) is 8.2 volts, and its maximum working current is 110 mA. The Zener resistance is 2.2 ohms and its maximum power dissipation is 800 mW. The surge current capability is 5 A and its maximum operating temperature is +85 degrees Celsius.

Mechanics, Structure and Interface

The KDZVTR8.2B is an internally-stabilized diode with a hermetically-sealed metallic case and a lead frame, with a copper alloy contact. The diode is contained in a 1.2mm thick package of high-temperature plastic, which provides insulation from environmental elements. Its physical dimension is 4.0×6.35mm both in length and width. The end terminal is the cathode of the diode.

The KDZVTR8.2B features a glass-filled thermoplastic (V0) package and flammability resistance. It has a short circuit current rating of 15A, with a maximum surge current of 5A. It meets the requirements of RoHS and can be triggered with AC or DC power.

Working Principle

The KDZVTR8.2B works with the same principle as other Zener diodes: when the forward voltage applied to the terminals reaches a certain voltage, known as the Zener voltage (breakdown voltage in some cases), it bypasses the current to a different terminal, thereby regulating the voltage within the circuit and preventing damage. This also allows the diode to be used as a voltage regulator in high power applications.

The KDZVTR8.2B can withstand higher power applications due to its hermetically-sealed package, which is highly temperature-stable. In addition, its Zener resistance and short circuit current-ratings provide an assurance of the diode’s performance in high power and high frequency applications.

The KDZVTR8.2B also has its advantages: it is very efficient, with a maximum power dissipation of 800 mW, which is much greater than that of its competitor. Furthermore, it is also more reliable, thanks to its metal case, which helps to protect the parts from environmental factors. This makes it an ideal choice for high-powered applications.

Conclusion

The KDZVTR8.2B is a single-terminal, hermetically-sealed, Zener diode designed to be used in a variety of AC/DC circuit applications, particularly high power and high frequency applications. It includes an isolated metal case which makes it highly temperature-stable and reliable. This diode can be triggered with both AC and DC power. Its Zener resistance and short circuit current-ratings provide extra assurance of its performance in high power applications, making it a great choice for many projects.
