Zener diodes are commonly used as voltage references and as shunt regulators to regulate the voltage across small circuits. They are also used to protect circuits from over voltage, by allowing the current to find a path around the circuit when the voltage exceeds a certain value. BZV85-C27, 133 is a single Zener diode, designed to guard against overvoltage and provide a reference for circuit design and protection.

Overview of BZV85-C27, 133

BZV85-C27, 133 is a Zener diode with a rated voltage of 13.3V, ideal for maintaining and protecting a circuit from exposure to overvoltage. It features a tolerance of 5%, and is available in a DO-35 package, designed for ease of installation and minimal board space. The diode\'s power dissipation is 550mW, making it suitable for use in circuits that require the protection of a high-power voltage reference. It has a low reverse leakage current of 7μA and a capacitance of 7.8pF at 4V, contributing to its efficiency and performance.

Working Principle

The working principle of a Zener diode is simple, but effective. In normal operation, they behave as a normal diode, allowing current to travel in one direction. When the voltage across them exceeds the Zener voltage rating, however, the diode begins to conduct in both directions, thereby limiting the voltage to the desired value. This works by allowing a small current to flow in the opposite direction, thereby reducing the total voltage to the desired level.

When the current flowing through the diode exceeds the breakdown level, the diode gets heated and its thermal resistance increases. As a result, the current flowing through the diode is reduced, limiting the voltage across the diode. This is why BZV85-C27, 133 is designed with such a low power dissipation of 550mW, to ensure that the diode will not overheat.
