Introduction

Transient Voltage Suppressor (TVS) diodes, also known as Transient Voltage Clamp (TVC), are electro-thermal devices used to protect high-speed data lines from electrostatic discharge (ESD), electrical overstress (EOS), and electrical transients caused by lightning, motor start-ups, and other high-voltage events. TVS diodes are available in many different configurations, including surface-mount devices (SMDs), through-hole devices (THDs), and planar technology. The NSPM0101MUT5G is a transient voltage suppressor (TVS) diode.

Application Fields

The NSPM0101MUT5G TVS diode is capable of withstanding transient voltages up to 5.2V, making it suitable for protecting components from voltage surges present in high-speed I/O buses, long-haul communications, LAN/SAN applications, and other high-speed digital or analog signals. In addition, its 125c rating makes it suitable for use in both commercial and automotive applications.

Features

The NSPM0101MUT5G is a 5V transient voltage suppressor (TVS) diode with a maximum clamping voltage of 3.0V. It features an electro-thermal protection circuit that provides protection from voltage surges without sacrificing signal integrity. It has a low stand-off voltage of 0.8V for maximum ESD protection. The device has an operating temperature range from -55°C to 125°C and is RoHS compliant.

Working Principle

TVS diodes protect sensitive electronic components from electrostatic discharge (ESD) and transient voltage spikes. When an ESD event occurs, the TVS diode conducts current to divert the surge of electricity away from the component. The diode operates in three stages: clamping, absorption, and reset. The clamping stage begins when a voltage greater than the breakdown voltage is applied to the diode. This causes the diode to conduct current, which clamps the voltage below the breakdown voltage of the diode. In the absorption stage, the diode absorbs the energy of the surge. Finally, in the reset stage, the diode returns to its normal, non-conducting state.

Conclusion

The NSPM0101MUT5G TVS diode is a robust, electro-thermal device for protecting high-speed data lines from voltage surges. It can withstand voltage levels up to 5.2V, has a low stand-off voltage of 0.8V, and operates over a wide temperature range. The device has three stages of operation: clamping, absorption, and reset. It is suitable for a wide variety of applications, including high-speed I/O buses, long-haul communications, LAN/SAN applications, and digital or analog signals.
