This type of diode is mainly used in Telecommunication, High-Tone and Automation Equipment, Automotive Systems, Medical Diagnostic, and various other power applications.

SZMMBZ5248ELT1G offers dual performance such as high-speed switching and low forward voltage drop along with low reverse recovery time and low capacitance. This type of diode also provides maximum thermal performance, instant-on, and high reliability.

Physical Characteristics

SZMMBZ5248ELT1G’s delivery tube contains 15 diodes. Its physical dimensions are 1.3mm x 0.8mm with a peak reflow temperature of 260°C. Its maximum operating junction and storage temperature ranges are 150°C and 150°C, respectively.

Operating Characteristics

The maximum continuous reverse voltage of SZMMBZ5248ELT1G is 5.0V. Its maximum power dissipation is 500mW. The reverse recovery time is 7.0ns and its capacitance is typically 5.8pF. The breakdown voltage of this type of diode is 5.0V.

Working Principle

SZMMBZ5248ELT1G functions as a voltage clamp to control voltage regulation based on the Zener mechanism. It mainly works as a shunt regulator by allowing the current to bypass the device when the reverse voltage exceeds the threshold. This type of diode can also be used as a voltage regulator to ensure voltage accuracy and stability.

When the voltage exceeds the breakdown voltage of SZMMBZ5248ELT1G, the electron–hole pairs created will be swept away by the electric field. The current flowing through the device will increase until the device reaches the Zener voltage. This will allow the excess current to be bypassed, protecting the device from current overloads.

Advantages

One of the main advantages of SZMMBZ5248ELT1G is its thermal performance. It is capable of efficiently transferring heat away from the device, thus allowing it to operate at higher temperatures. It also offers low capacitance and reverse-recovery time, which are important for applications requiring fast switching.

Another main advantage of SZMMBZ5248ELT1G is its high reliability. Its single-package design allows it to operate in high temperature and severe environments without compromising its performance. Its high precision also ensures accuracy and stability, making it a suitable choice for various power applications.

Disadvantages

The main disadvantage of SZMMBZ5248ELT1G is that it requires a relatively high voltage to function effectively. It also requires a large physical package, which limits its usage in some applications. Additionally, its maximum voltage is limited to 5.0V, which may not be suitable for some high-power applications.

Conclusion

SZMMBZ5248ELT1G is a single Zener diode part mainly used in Telecommunication, High-Tone, Automation and Automotive equipment, Medical Diagnostic, and various other applications. It offers high-performance capabilities such as low forward voltage drop and high-speed switching as well as high reliability. Despite its advantages, it requires a relatively high voltage to operate and its package size limits its use in some applications.
