SMDA15C-7/TR7 Application Field and Working Principle

TVS (transient voltage suppressor) diode is an excellent device for protecting electronic circuits from over-voltage or surge events. SMDA15C-7/TR7 is a TVS diode with a peak pulse power rating of 600W and a breakdown voltage of 15V, This device is designed to provide superior protection against transient voltage and surge events. In this article, we discuss the application fields and working principles of SMDA15C-7/TR7.

Application Field

SMDA15C-7/TR7 is widely used in the integration of overvoltage protection for various types of electronic circuits, such as:

• Telecommunication systems, such as telephone lines, mobile telephones, cable networks, and data communication networks.
• Computers, such as server systems, PC networks, printers, and modems.
• Industrial control systems, such as programmable logic controllers, variable frequency drives, and controllers.

SMDA15C-7/TR7is also widely used in the integration of electronic circuits, such as automotive, aviation, medical, and consumer electronics.

Working Principle

SMDA15C-7/TR7 works by limiting the peak voltage, reducing the voltage stress of the device, and preventing the circuit from damage. The device has two lower terminals (anode and cathode), between which a voltage clamp is formed. When the voltage applied between the two terminals meets the switching threshold voltage, then an avalanche breakdown occurs, after the avalanche breakdown occurs, the diode will operate in the zener breakdown region, and the voltage applied to the diode is limited.

When the voltage applied between the anode and cathode of the diode exceeds the specified limit, then the diode will conduct the current and reduce the voltage to the safe level. This process will repeat whenever the voltage rises above the specified limit. The peak pulse power rating of a diode is the maximum peak pulse power that the diode can withstand before it fails.

In conclusion, SMDA15C-7/TR7 is a great device for the integration of overvoltage protection for various types of electronic systems, with its peak pulse power rating of 600W and breakdown voltage of 15V, it offers superior protection against transient voltage and surge events.
