Introduction of MMBZ5248BTS-7-F

The MMBZ5248BTS-7-F is a integrated Zenoer diode array IC from Diodes Inc. It consists of four independent Zener diode, each with a breakdown voltage of 7.0 volts for a total package breakdown voltage of 28.0 volts. The MMBZ5248BTS-7-F is available in a convenient SOT-563 package, making it a reliable and cost-effective solution for applications requiring board space efficiency.

Application Field

The MMBZ5248BTS-7-F is an all-in-one solution for overvoltage protection and can be used in a wide variety of applications including automotive, industrial, medical, and consumer electronics. It can be used in combination with a TVS diode or other protective device to guard against errors or spikes in voltage. The MMBZ5248BTS-7-F is especially useful in power supplies, voltage regulators, and battery-charging circuitry, providing protection against reverse voltages and overvoltage.

Working Principle

The MMBZ5248BTS-7-F operates by limiting the voltage across it to the breakdown voltage, typically 7.0V. When the applied voltage reaches the Zener voltage of 7.0V, a small current starts to flow and the voltage is limited to its breakdown voltage. This voltage stabilizing process is commonly referred to as "clamping." With a single Zener diode, the voltage will remain at its clamping point once the breakdown voltage is reached. The MMBZ5248BTS-7-F, however, is an integrated diode array and thus uses multiple Zener diodes in parallel for higher current capacity and to reduce the effects of temperature and process variation. The MMBZ5248BTS-7-F is designed to operate at temperatures ranging from -55C to 150C and offers a low dynamic impedance of 0.2 W. It is rated to handle up to 5A of peak current flowing through the device.

Conclusion

The MMBZ5248BTS-7-F is an integrated Zener diode array IC designed to protect against overvoltage and reverse voltage. It is suitable for a wide range of applications such as automotive, industrial, medical, and consumer electronics. The MMBZ5248BTS-7-F offers a breakdown voltage of 28.0V, supports operating temperatures from -55C to 150C, and is rated up to 5A of peak current. With its small SOT-563 package, the MMBZ5248BTS-7-F is an economical and reliable solution requiring minimal board space.
