These applications include: reverse polarity protection, low noise power supplies and AC/DC converters. As mentioned above, it is also ideal for applications in which a given voltage level must be maintained even if the applied voltage fluctuates. Due to its high surge current and temperature stability, CMDZ5246B BK is also suitable for use in high-dynamic electricity grids, and it is often used in automotive electronics, where it ensures the longevity of the vehicle\'s components by providing a satisfyingly clean electrical power supply. Furthermore, CMDZ5246B BK is also used for powering LED lights, LED drivers and LED controllers.

Working Principle:

The CMDZ5246B BK is a single Zener diode, meaning that it is a two-terminal element which, when operated, allows a current to flow in one direction, known as the forward direction, while blocking any current flow in the opposite direction, the reversed direction. This is due to the operation of a PN junction in the silicon semiconductor of the diode. In the forward direction, the diode behaves as an ordinary diode, allowing a small voltage drop across the diode. But when the reverse voltage across the diode exceeds the breakdown voltage, which can be controlled by the doping concentration in the PN junction of the diode, the diode begins to conduct in the search direction, resulting in a low voltage drop. This results in a constant voltage reference that cannot be exceeded by the applied voltage, ensuring a stable flow of electricity.

Conclusion:

The CMDZ5246B BK is a single Zener diode manufactured by CMOS Technologies. This diode is used in a variety of applications, with its primary function being to provide a reliable voltage reference. It can be used in a wide range of applications, from reverse polarity protection through to LED controllers. The CMDZ5246B BK is ideal for applications that require a reliable voltage reference and high surge current capability, due to its low dynamic resistance and temperature stability.
