BZX55B36-TR Datasheet/PDFDiodes - Zener - Single
The BZX55B36-TR 30v 0.5w Zener diode is a breakdown diode. Its main application fields include regulating voltage, temperature compensation, and providing protection against electrostatic discharge (ESD) and electromagnetic interference (EMI). This diode is made of silicon epitaxial planar construction, and is hermetically sealed in a glass-encased SOD-27 package, thus allowing it to withstand environments of high humidity.
Application Field
The BZX55B36-TR is suitable for a variety of applications, such as regulating voltage in digital and linear circuits, providing protection against ESD and EMI, as well as temperature compensation. In addition, this diode is able to provide voltage regulation and voltage clamp with minimal power dissipation.
Working Principle
The working principle of a Zener diode is based on the ability of the semiconductor junctions to breakdown and conduct electric current in reverse biased state. As the reverse voltage increases, it reaches the breakdown voltage, which is known as the Zener voltage. After the breakdown voltage is passed, the voltage remains very stable and current starts to flow through the the diode. The result of this breakdown is known as Zener breakdown.
The Zener breakdown temperature is determined by the temperature coefficient of Zener voltage, which is defined by the Zener diode\'s thermal noise. This noise produces a variation in the Zener voltage with temperature, resulting in a noise-free operation of the diode. This temperature coefficient is heavily affected by the junction area of the diode, and its thermal resistance.
Packaging
The BZX55B36-TR is assembled in SOD-27 glass package, with gold-plated contacts to help prevent corrosion. The glass-encased diode provides hermetic sealing, which makes it ideal for applications in extreme environments. The hermetic sealing also makes it easier to connect the diode to the circuit via soldering.
