Thyristor surge protectors are an important part of TVS (transient voltage suppressor), regardless on how developed the current electronic industry is, it is still necessary to use TVS to provide the over-voltage protection for the integrated circuits, microcontrollers, discrete semiconductor devices and other usage application. In the over-voltage protection, the SMC3K60CAHM3/9A from AVX is a great choice. This component is specially designed to protect against heavy surge and ESD events. Therefore, let’s go through the application field and the working principle of the SMC3K60CAHM3/9A.

The SMC3K60CAHM3/9A is a silicon thyristor who is designed for bidirectional working. This component is featured with low trigger power, easy to trigger, and can withstand high electrical breakdowns. It is also designed with low capacitance. The substrate used for this component is planar technology. The simple construction of the component is another factor for its high reliability. With all of the features, the SMC3K60CAHM3/9A is an ideal component for ESD and surge over-voltage protection. It provides bidirectional protection, this feature is the most effective in low power signals.

In terms of application fields, the SMC3K60CAHM3/9A is mainly used in clamped protection in ESD and surge over-voltage protection. It is also perfect to be used in the automotive, communication, medical equipment, industrial equipment, military aviation, or other similar application fields. Bear in mind that this component is not suitable in low power signals, such as data line in computer and other similar application. This is due to its low capacitance. The maximum current can handle with the SMC3K60CAHM3/9A is 3A.

Now let’s talks about the working principle of the SMC3K60CAHM3/9A. It is all started when there is a thunderstrike, a high voltage surge will be produced from the ground via lightning. The lightning may also cause direct damage to your system. To prevent such situation from taking place, the TVS will start to take the action. The SMC3K60CAHM3/9A acts like a diode, it will direct the surge voltage to the ground or divert it to different circuit. When the surge is diverted, it will experience a current limiting because of the low capacitance. On the contrary, when the surge is sent to the ground, it can also be reduce the voltage and prevent the system from any damages.

The SMC3K60CAHM3/9A by AVX is a great component for over-voltage protection. It is featured with low trigger power, low capacitance, and ESD and surge protection capabilities. Its application fields are clamped protection in ESD and surge over-voltage protection, specifically automotive, communication, medical equipment, industrial equipment, military aviation, and other related fields. The working principle is simple, when there is a high voltage surge, it will converts the energy to the ground or different circuit with the help from the low capacitance.
