Diodes are semiconductor devices which conduct electric current in one direction, allowing flow from an anode to a cathode. Zener diodes are specialized diodes which allow current to flow in either direction, depending on the voltage applied to them. A single Zener diode is a diode made up of a single p-n junction. The CMPZ5252B BK is a single Zener diode designed and manufactured by ON Semiconductor. This diode is designed primarily for use in power conversion, or power management, applications.

The CMPZ5252B BK is a high voltage, high power, single Zener diode, with a breakdown voltage of 2.5V. It is made with an epitaxial planar process, which is a method of introducing impurities into a silicon substrate. The diode is rated at a current of 10A, and has a power dissipation of 16 watt.

The CMPZ5252B BK is generally used in applications where a low dropout voltage and high output current are required. It is often used in DC-DC converters, switching regulators, and isolated DC-DCs. The diode can also be used for Zener clamp applications, which are used to protect circuits from transient overvoltage. The diode features a low total capacitance and an integrated EMI filter. It also comes in an SOT-223 package, making it suitable for use in various types of applications.

The working principle of the CMPZ5252B BK is fairly simple. When the diode is forward biased, the voltage applied across its terminals causes the current to flow from anode to cathode, as it normally would. When the diode is reverse biased, it begins to break down at a certain voltage, known as the breakdown voltage. The current released in breakdown can be anywhere between a few milliamps to several hundred amperes.

The CMPZ5252B BK is a versatile and reliable single Zener diode with several applications in the power management field. It offers a breakdown voltage of 2.5 volts, and is rated for a current of 10 amps and a power dissipation of 16 watts. It features a low total capacitance and an integrated EMI filter, as well as an SOT-223 package for easy integration and mounting. Along with its simplicity, these features make the CMPZ5252B BK an ideal diode for many power management applications.
