Introduction

The MXLUPTB10E3 is an ultra-low capacitance transient voltage suppression (TVS) diode specifically designed to protect sensitive circuit board components from electrical overstress during transient events such as \'ESD- (electrostatic discharge) induced voltage spikes.Compared to the standard TVS diodes, the MXLUPTB10E3 offers superior protection against ESD- and surge type of transients.

Application

MXLUPTB10E3 can be used in several applications.First and foremost, by installing them on the circuit board, they can be used to protect against electrostatic discharge (ESD) and fast transient surges by providing a low-impedance path to ground.This is particularly useful in electrostatically sensitive applications such as interface and peripheral devices in automotive, consumer electronics, communications, and medical applications.Furthermore, MXLUPTB10E3 is also compatible with current IEC 61000-4-2 and IEC 61000-4 standards for ESD protection.Finally, the MXLUPTB10E3 is ideally suitable for systems & applications that require very low capacitance TVS, including, but not limited to, USB3.0, Thunderbolt, and onboard buses of laptops as well as other applications where speed and maximum surge current protection is important.

Working Principle

The working principle of the MXLUPTB10E3 is relatively straightforward - it provides a low-impedance path to ground for transient pulses while allowing normal circuit operation.This is done by quickly clamping any voltage surge over a certain threshold to a near-ground voltage level.To achieve this, the MXLPUTB10E3 uses an avalanche breakdown diode.When the voltage across the TVS exceeds the threshold value, an avalanche breakdown takes place where free carriers are generated and travel in a reverse direction.This creates an avalanche current where a current of more than 10A can be supported for a short period.The avalanche current quickly clamps the overvoltage to a very low level, typically between 7V and 14V.

Conclusion

The MXLUPTB10E3 is an ultra-low capacitance transient voltage suppression diode specifically designed to protect sensitive circuit board components from electrical overstress during transient events. It offers superior protection against ESD- and surge type of transients, is compatible with current IEC 61000-4-2 and IEC 61000-4 standards for ESD protection, and is a suitable choice for applications that require very low capacitance TVS. The working principle behind the MXLUPTB10E3 involves quickly clamping any voltage surge over a certain threshold to a near-ground voltage level using an avalanche breakdown diode.
