Introduction

SZMMBZ5240ELT1G is a Zener diode in a SMA (DO-214AC) package, within the Single diode family, that is widely used as a voltage regulator and current limiter in a number of electronic devices. It has a peak reverse voltage of 5.6V and an average forward current of 1A. It is an ideal device for use in demanding environments that require high performance and durability.

Application Field

SZMMBZ5240ELT1G is ideal for a variety of applications, such as automotive, consumer, computers, and industrial electronics. Its high peak reverse voltage and high forward current make it perfect for use in high-voltage, current-limited circuits. It also has wide industry-standard footprints, so it is easy to integrate into new and existing designs. Additionally, its small size makes it suitable for low-profile circuit designs, such as cell phones and tablets.

Working Principle

SZMMBZ5240ELT1G functions as a Zener diode, meaning that it acts like a standard diode, but with an adjustable breakdown voltages. When the input voltage reaches the breakdown voltage, the diode switches on and conducts electric current in the reverse direction, effectively limiting the voltage. The breakdown voltage can be determined by selecting a Zener diode with an appropriate reverse breakdown voltage.

Aside from limiting voltage, the SZMMBZ5240ELT1G can also be used to provide polarisation protection from electrical transients. Electrical transients can cause significant damage to electronic circuit boards, as they can jump over components and cause damage that is difficult to repair. By using SZMMBZ5240ELT1G to shunt the transient, the peak voltage can be reduced to a safe level, protecting the circuit board from excessive damage.

Conclusion

SZMMBZ5240ELT1G is a Zener diode which finds its application in a number of industries, and is ideal for high-voltage, current-limited circuits. It works by limiting the input voltage to a safe level, and can also provide polarisation protection. Because of its small size, it can be used in low-profile circuit designs.
