Overview

The SMBJ4752A/TR13 is a surface-mount avalanche voltage suppressor, integrated into a single package. This Zener diode has a voltage rating of 12V, with a power dissipation of 300mW. It has a temperature range of -65 to +175 degree Celsius, allowing it to operate properly even in extreme conditions. Furthermore, it has a nominal breakover voltage of 11V and a 5-sigma segment reliability of 0.3%.

Application Field

The SMBJ4752A/TR13\'s features make it an ideal choice for a wide range of applications, such as protecting sensitive electronics from electrical surges, overvoltage, and short circuit events. It is often used in low and medium voltage power supplies, automotive electronics, telecommunication equipment, and consumer electronics. The SMBJ4752A/TR13 can also be used as a clamping device or voltage regulator in voltage-controlled circuits, further improving its versatility.

Working Principle

The SMBJ4752A/TR13 works like a typical Zener diode, using the Zener effect to control the voltage levels. When connected to a power source, the diode is designed to allow a current to flow in one direction only. Once the voltage exceeds the breaking point of 11V, the diode then becomes reverse biased and starts to conduct electricity in the opposite direction. This action generates an opposite voltage, which prevents the input voltage from exceeding the threshold.

The SMBJ4752A/TR13 also has a reverse leakage current, which is the measure of current flowing from the diode when in the reverse bias state. This is an important parameter that needs to be taken into consideration while selecting this diode, as it will affect the overall performance. Lastly, the operating temperature of the SMBJ4752A/TR13 needs to be taken into account, as it will affect the electrical characteristics of the diode.

Conclusion

In summary, the SMBJ4752A/TR13 is an ideal choice for a variety of applications due to its compact size and high power rating. Its Zener voltage of 12V and 5-sigma segment reliability of 0.3% make it exceptionally reliable and effective. Moreover, the diode has excellent temperature performance, allowing it to function in both normal and extreme conditions. By understanding the application field and working principle of the SMBJ4752A/TR13, engineers will be able to leverage its features and make the most out of it.
