TVS or Transient Voltage Suppressors are designed to protect sensitive components from exposure to high voltage surges. They are a type of semiconductor, usually a diode, that limits the voltage applied to any electrical circuit to a safe amount. SMDA03C-8/TR13 is a surface mount, bidirectional voltage clamping device specifically designed to protect sensitive equipment from damaging transients. The device is designed to withstand 8kV of electrostatic discharge (ESD) and has a peak pulse power rating of 140W.

Applications of SMDA03C-8/TR13 include automotive systems, medical equipment, communication system, consumer electronics and computers. The device has a low capacitance of 0.7pF, making it suitable for high-speed applications such as digital circuit designs. It has a breakdown voltage of 3.0V, which is suitable for protecting sensitive circuits from both positive and negative overvoltage transients.

Working Principle

The working principle of SMDA03C-8/TR13 is simple: it provides a clamping voltage of 3.0V which limits the amplitude of any voltage surges that occur on the line to keep it within a protected range. The device has a nonlinear, zener-based clamping action and reverse Stand-off voltage of 3V. This allows the voltage clamp to block any potential voltages of more than 3V, and the limited voltage allows the device to minimise any potential for damage from overvoltage transients.

Features

SMDA03C-8/TR13 includes several features that makes it an ideal device for protecting against overvoltage transients, such as:

• 8kV ESD Protection
• Bi-Directional with 3V Breakdown Voltage
• Peak Pulse Power Rating of 140W
• Low Capacitance of 0.7pF
• Surface Mount Package

The device is also RoHS compliant, which means it is manufactured to be safe for the environment and does not contain any hazardous substances.

Benefits

The benefits of using SMDA03C-8/TR13 are that it is easy to install and use, it requires minimal components and it provides reliable and robust protection. The 8kV ESD protection allows for a high level of protection and the low capacitance of 0.7pF enables fast response times. In addition, the device is surface mount which makes it suitable for use in tight spaces. The high peak pulse power rating of 140W also ensures that the device is able to handle large voltage transients.

Conclusion

SMDA03C-8/TR13 is an ideal solution for protecting sensitive equipment from overvoltage transients. The device has a breakdown voltage of 3.0V, 8kV electrostatic discharge protection, and a peak pulse power rating of 140W. It is a surface mount device with low capacitance of 0.7pF. It is RoHS compliant and provides reliable and robust protection. The main benefits of using SMDA03C-8/TR13 are its small size, low cost, and easy to use installation.
