Transient Voltage Suppressors (TVS) are components designed to protect electronic circuits from voltage spikes such as electrostatic discharge (ESD), lightning, or induced surges. TVS diodes are one of the main types of TVS used in protecting circuits from voltage transients. SM30T28AY is a type of TVS diode commonly used in circuit applications. This article will discuss the application field and working principle of the SM30T28AY.

Application Fields of SM30T28AY

The SM30T28AY is a unidirectional bi-directional transient voltage suppression (TVS) diode. It has a low capacitance and is capable of handling up to 28A peak current. Due to these attributes, the SM30T28AY is widely used in applications such as automotive, industrial, and consumer electronic equipment, as well as in power supplies, routers, and other high-frequency applications. Its low capacitance also makes it a popular choice for use in protection against EMC disturbances in sensitive circuits. In addition, its wide operating temperature range from -55°C to 175°C makes it suitable for use in a wide range of applications.

Working Principle of SM30T28AY

SM30T28AY is a type of TVS diode designed to provide protection against transient voltage spikes. It utilizes a Zener diode as its main component. When a transient voltage spike occurs, the voltage spike causes the Zener diode to breakdown and conduct current, thus limiting the voltage spike. At the same time, the Zener diode also generates heat to dissipate the voltage spike energy.

The SM30T28AY also utilizes a low capacitance structure, enabling the device to respond to transient voltage spikes faster than standard TVS diodes. This means that the SM30T28AY can offer superior protection against high speed transient voltage spikes compared to other TVS diodes. Moreover, the SM30T28AY is also capable of handling up to 28A peak current, allowing it to protect sensitive circuits with higher transient currents.

Conclusion

The SM30T28AY is a type of TVS diode that is designed to provide protection against transient voltage spikes and can handle up to 28A peak current for superior performance. It is designed with a low capacitance to allow it to respond and dissipate the voltage spike energy faster than standard TVS diodes, and its wide operating temperature range makes it suitable for a variety of applications. The SM30T28AY is used in automotive, industrial, consumer electronic equipment, as well as in routers, power supplies, and other high-frequency applications.
