TVS diodes are an integral part of the protection solution of systems and circuits that must operate in electrically hostile environments. Lightning, electrostatic discharges, electrical transients and other overvoltage events do not discriminate between circuits, making the need for protection from very high voltage events greater than ever. The TPD5E003DPFR TVS diode is part of the TPD family of TVS diodes from ON Semiconductor and provides the protection needed from these high voltage events.

The TPD5E003DPFR is a 2.9 W unidirectional, bi-directional or common-mode protection diode. It is available in a SOD-323 small-footprint package and provides surge protection with low capacitance, making it ideal for protection or EMI/RFI filters in today’s high-speed communication systems. The electrical characteristics of the TPD5E003DPFR make it ideal for use in automotive, industrial and consumer applications.

The TPD5E003DPFR diode is designed to protect against up to 1000W of peak pulse power and has a breakdown voltage of 16V. It has a low capacitance of 35pF typical, along with a very fast response time of less than 1ns. The TPD5E003DPFR also features excellent clamping capability with a low leakage current of 300uA at 600V.

In terms of application fields, the TPD5E003DPFR diode is suitable for a variety of applications, ranging from automotive to industrial. The TPD5E003DPFR’s low clamping voltage and fast response time make it suitable for high-speed communication systems such as USB, Thunderbolt, Ethernet, HDMI, and digital audio. It can also be used in automotive applications such as powertrain, brake, and body protection. Additionally, the diode is suitable for EMI/RFI filters used in high-power switching applications, as it can handle large di/dt with low capacitance levels, making it an ideal solution for the protection and filtering of high-frequency signals.

To understand how the TPD5E003DPFR works, it is important to understand the principles of TVS diodes. TVS diodes are basically small intravenous rectifier diodes clamped together in an array. When an overvoltage occurs, the TVS diode can clamp down to a preset voltage, thus restricting the flow of current. The overvoltage is then dissipated, or “clamped”, in the diode, allowing the circuit to safely remain on. This is accomplished due to the change of impedance the diode offers when different voltages are applied. Additionally, TVS diodes also offer excellent EMI and RFI protection.

In conclusion, the TPD5E003DPFR diode is a great solution for the protection and filtering of high voltage and high frequency signals. Its low capacitance, high peak power handling, and low leakage current make it an ideal choice for automotive, industrial, and consumer applications. Additionally, understanding the working principle of TVS diodes provides greater insight into how the TPD5E003DPFR works.
