Introduction

CMDZ5249B BK is a single Zener diode typically used in various applications. It has wide range of working voltages and low breakdown voltage. It is a reliable device for applications where reverse breakdown voltage is important. It can be used in low voltage switching between loads, high speed switching, and low current operation.

Structure and Working Principle

The CMDZ5249B BK consists of a single Zener diode usually formed of two semiconductor layers forming a P-N junction. It has a diode structure with a reverse breakdown voltage at a certain point of applied voltage. In normal operation, the applied voltage is less than the breakdown voltage and the diode operates in its forward biased region. When the voltage reaches the breakdown voltage, current will start to flow through the device in the opposite direction. This phenomenon is known as the Zener breakdown. The voltage at which the reverse breakdown occurs is the Zener voltage. At this point, the resistance drops drastically, allowing the current to increase.

The working of the diode mainly depends on the voltage drop across the diode which can either be in forward or in reverse direction. When the applied voltage is low, or below the Zener voltage, a very little current flows through the diode, because the diode acts nearly as an open circuit. The current decreases exponentially with increasing voltage until it reaches the Zener Voltage, at which point the diode starts to conduct, and the current will then increase at a faster rate.

Application Fields and Uses

CMDZ5249B BK single Zener diodes are widely used in a variety of applications. It is used in voltage regulation, rectification, and pulse generation.

The diode is also used in battery-operated devices where it is used to prevent excessive voltage drain when the load is low or during high temperature conditions.

In addition to the above applications, the diode is also used in data switches, digital logic circuits and protection circuits. In all these applications, the diode ensures that the voltage remains within the correct limits, allowing the device to work reliably and efficiently.
