Introduction to SZMMBZ47VALT1G

The SZMMBZ47VALT1G is a type of diode array developed by NXP Semiconductore, a leading multinational semiconductor manufacturer. This diode array is part of their Zener diodes range, designed to provide high-performance and robust point-of-load voltage regulation.

Application Field

The SZMMBZ47VALT1G is an excellent choice for applications that require both precision regulation and high current handling capability. It is suitable for high power applications such as power supplies, telecom equipment, computers, and automotive systems. The diode array can also be used as a circuit protection device, helping to protect delicate sensitive components from excessive voltage.The SZMMBZ47VALT1G is also suitable for higher power switching regulators. It has the ability to handle peak currents up to 4.6A and can provide precise current regulation with very low power dissipation. It is also very efficient, with a power dissipation of only 205mW at a temperature of 70°C.

Working Principle

The SZMMBZ47VALT1G is a diode array that ensures precise voltage regulation. It comprises two series-connected diodes which form a double-sided current swing regulator. These two diodes work together to form a precision regulator, regulating the primary circuit current to maintain a specific voltage on the secondary side.The two diodes used in the array are connected differently. The first diode is connected in series between the power source and the load, while the second diode is connected to the source and the load in parallel. This means that each diode functions differently, regulating both the input and output current. The main advantage of the SZMMBZ47VALT1G is its ability to precisely regulate the voltage. It uses feedback from the load circuit to adjust the voltage, maintaining it at a precise level. This is achieved by the continuous monitoring of the input voltage and the load current. If the load current changes, the regulator will respond by adjusting the voltage output in order to keep it at the desired level.

Conclusion

The SZMMBZ47VALT1G diode array is a precision regulator, suitable for use in applications that require both high power handling capability and precise regulation. It is an efficient and robust device with a power dissipation of only 205mW. It is also capable of regulating both the input and output current, ensuring precise voltage regulation.
