TVS - Diodes

Transient voltage suppressor (TVS) diodes, also known as Transient Voltage Suppression (TVS) diodes, are semiconductor components used to protect circuits from overvoltage transients, which may occur due to lightning, power faults, switching transients, or inductive loads. The SMAJ350E3/TR13 TVS diode is one such component. This article will focus on its application fields and working principle.

Application Fields

The SMAJ350E3/TR13 TVS diode is designed for use in high speed data line and computer peripheral applications such as Ethernet, USB, Serial ATA, and more. It is particularly well-suited for applications where the ESD and surge protection will be exposed to environmental temperatures ranging from -65˚C to 150˚C.This diode has a fast response time, high transient working peak voltage of 350 W, and a low dynamic resistance of 0.83 ohms. Its operating peak pulse of current 20KA (8/20 μs) makes it ideal for protecting power systems and communications lines.

Working Principle

When the voltage in a power system or communications line transiently exceeds the TVS diode\'s designed breakdown voltage, it will begin conducting. The current through the diode is limited by the external resistance connected to it. The excess energy is then dissipated as heat. This prevents the transient voltage from damaging the connected components or circuits. TVS diodes feature low capacitance and low let-through voltage characteristics, which limit the amount of current and voltage that can pass through the component and to the device under protection.Once the voltage has dropped to a safe level, the diode will automatically switch off. This reduces the potential for further damage to the device, as well as any connected circuit boards or systems.

Conclusion

The SMAJ350E3/TR13 TVS diode is a useful component for the protection of power systems, communications lines, and other vulnerable electronics from overvoltage transients. It has a high transient working peak voltage, a low dynamic resistance, a low capacitance, and a low let-through voltage. This helps to ensure that the device and the connected components are protected from damage due to voltage or current overloads.
