TVS (Transient Voltage Suppressors) diodes are an integral component of modern electrical and electronic systems, and are used to protect sensitive electrical components from overvoltage surges. SMB10J5.0HE3/52 is a TVS diode specifically designed to provide overvoltage protection to circuits operating at 10V and below. In this article, we will discuss the application field and working principle of the SMB10J5.0HE3/52 TVS diode.

Application Field

The SMB10J5.0HE3/52 is a unidirectional TVS diode designed specifically for applications that require 10V and below. It is suitable for applications such as automotive electronics, data communications, RF circuits and other general electronic circuits. Its small size and low voltage rating make it ideal for use in space-constrained applications. It is also compatible with many surface-mount manufacturing processes and packages.

The SMB10J5.0HE3/52 is designed to provide protection from dangerous overvoltage surges, which can cause significant damage to sensitive electronic components. The diode is designed to have a high peak pulse current rating of 5.0A, allowing it to effectively protect sensitive components from overvoltage transients. This high peak pulse current rating also makes the diode suitable for use in harsh environments, such as automotive, industrial and medical applications.

Working Principle

The SMB10J5.0HE3/52 operates on the principle of diode reverse-bias breakdown. When the voltage across the diode exceeds its breakdown voltage, it starts to conduct current in the reverse direction. The current flowing through the diode is limited by the device’s internal resistance, and the diode acts as a clamp, limiting the voltage across the circuit to the diode’s reverse breakdown voltage. In this way, the SMB10J5.0HE3/52 effectively protects sensitive electronic components from overvoltage surges.

It is important to note that the TVS diode will enter a ‘non-conductive’ state as soon as the voltage across it drops to a safe level. This ensures that the circuit will remain protected against further overvoltage transients until the voltage drops to a safe level and the diode returns to its original non-conductive state. This is advantageous in that it reduces the need for secondary protection devices, such as fuses, which are often caused by multiple surges.

Conclusion

The SMB10J5.0HE3/52 is an ideal choice for applications requiring overvoltage protection at 10V and below. It is specifically designed to provide high peak pulse current protection and is suitable for use in harsh environments. Its small size and compatibility with surface-mount manufacturing processes make it an ideal choice for space-constrained applications. Moreover, its ability to switch from a non-conductive state to a conductive state ensures effective protection against further overvoltage transients.
