The MMBZ5225BS-7 is a two-terminal Zener diode array that provides very low on-chip capacitance and low reverse leakage. It offers higher power dissipation and a better temperature coefficient than a single diode. It can provide a good temperature stability across a wide temperature range and good avalanche capability.

Application Field

MMBZ5225BS-7 diodes are commonly used for a variety of applications such as voltage regulation, automotive under-the-hood, handheld, laptop and notebook computers, digital displays, and power regulators. They are also used in high frequency switching, power management applications, over-voltage protection and other applications that require high reliability and durability.

Working Principle

The MMBZ5225BS-7 diode array is based on the Zener breakdown principle. Zener breakdown is a phenomenon in which a high electric field breakdown occurs in a reverse-biased junction, resulting in a device that looks like a conventional diode but exhibits reverse breakdown behavior. The Zener diode provides a low voltage drop and low reverse current while allowing conduction during the reverse bias. The device features an epitaxial zinc oxide layer that is highly resistant to breakdown and has a higher temperature coefficient than an ordinary silicon diode. It also has a high differential resistance that helps minimize switching losses.

The MMBZ5225BS-7 is a multi-diode array with a single common anode and separate cathode connections for each diode. It operates with a forward voltage drop of 0.3 volts, a maximum reverse voltage of 24 volts, and a maximum junction temperature of 175°C. The device can handle a range of currents up to 500mA, making it suitable for higher power applications. The device is packaged in a flat flexible carrier (FFC) package that makes it easy to connect and assemble. The device is manufactured using advanced planar Zener diode technology to ensure reliability and consistency.

The MMBZ5225BS-7 diode array is the ideal choice for applications that require low on-chip capacitance and low reverse leakage, such as voltage regulation, power management, and automotive under-the-hood applications. This diode array is able to provide a low voltage drop and low reverse current, even at high temperatures, making it an excellent choice for a wide variety of applications.
