Diodes - Zener - Single

The MAZ251000G Zener diode is a voltage regulator created by Bourns. With a low cost, it is widely used in various switch mode power supplies (SMPS), LED drivers, load dumps, and other overvoltage protection. The MAZ251000G diode is constructed in a small SOD-123 package for compatibility in low-profile designs. It also has a temperature range of -55 to +150°C for use in thermally-disadvantaged designs.

Application Field

The MAZ251000G Zener diode is mainly used to regulate the output voltage of various electronic circuits. It is ideal for low-cost protection solutions, as it can provide protection in a variety of conditions. It is used in SMPS to improve efficiency, reduce losses, and extend the life of the SMPS. The MAZ251000G diode is also commonly used in LED drivers to prevent string current overloading, improve reliability and provide consistent levels of brightness. For automotive applications, the MAZ251000G diode is used in load dumps to provide overvoltage protection and protect against voltage spikes.

Working Principle

The MAZ251000G Zener diode uses a Zener breakdown character to regulate the output voltage. If the input voltage exceeds the rated voltage of the diode, the diode will start to conduct. This reverse current will cause the output voltage to drop, preventing any further voltage increase in the circuit. When the input voltage falls back below the rated voltage, the diode will stop conducting and the output voltage will return to normal.

The Zener breakdown character of the MAZ251000G diode is determined by the doping level. The doping level refers to the number of atoms in the semiconductor crystal lattice. A low doping level results in a lower breakdown voltage, while a high doping level results in a higher breakdown voltage. This allows the MAZ251000G diode to be used in a variety of applications with different levels of breakdown voltage.

The MAZ251000G Zener diode also provides transient protection. When a voltage spike occurs, the diode will conduct and absorb the excess energy, preventing it from traveling further and damaging other components in the circuit. This makes the MAZ251000G diode an excellent choice for overvoltage protection and surge protection applications.

Conclusion

The MAZ251000G Zener diode is a cost-effective, low-profile voltage regulator solution. It is used in a variety of applications from LED drivers to load dumps. It is also highly suited for transient protection applications due to its Zener breakdown character and its ability to absorb excess energy from voltage spikes. With its small size and reliable protection, the MAZ251000G diode is an excellent choice for a variety of applications.
