Transient Voltage Suppressor (TVS) diodes are a type of protective technology widely used in a variety of applications. The TPD4E110DPWR is an innovative and specific type TVS diode designed to protect electronic circuits from voltage transients in high-power systems. This article will discuss the application fields and working principle of the TPD4E110DPWR.

Application

The TPD4E110DPWR is designed to protect high power circuits from transient voltage spikes due to Electrostatic Discharge (ESD), Lightning, Inductive Switching and Electrical Overstress (EOS). According to the manufacturer, the TPD4E110DPWR has an standoff voltage of 10V, with a peak pulse current of 8.5A and a maximum clamp voltage of 16.7V. This wide range of application ranges from low and medium energy systems to high power systems.

In terms of application, the TPD4E110DPWR is suitable for use in Automotive, Industrials, railway systems, power supplies, motor control systems, and medical equipment. The ESD protection of the TPD4E110DPWR is specially designed to protect electronic circuits in harsh environments. It also has a comprehensive built-in ESD protection that can protect against static discharges up to 8kV, ensuring that the enclosed circuits are protected from any kind of damage.

Working Principle

The TPD4E110DPWR works by converting a high voltage surge or transient into a low voltage, low energy signal. It does this by utilizing a unique mechanism called “clamping”, or “avalanche”, in which the avalanche breakdown process is used to absorb the energy of the voltage transient and dissipate it in the form of heat. The breakdown in the diode occurs at its rated reverse breakdown voltage (VR) and allows the current to flow in the opposite direction.

The TPD4E110DPWR also utilizes a unique structure that allows it to withstand a high level of surge energy and clamp the voltage down to a much lower level without failure. This is achieved through the use of Zener diodes embedded in the device, which are designed to activate when a certain voltage level is reached, and then clamp the voltage at a much lower level. This ensures that the surge energy is absorbed by the device without overloading the circuit.

In terms of performance, the TPD4E110DPWR stands out in its ability to operate efficiently in high power applications. Its clamping voltage is rated at 16.7V, with a peak pulse current of 8.5A and a recovery time of less than 10µs, making it an ideal choice for high power applications. Additionally, it also has a great response time to electrical overstress, making it suitable for many other applications.

Conclusion

The TPD4E110DPWR is a state-of-the-art TVS diode designed to protect a wide range of electronic systems from voltage transients. It is suitable for a variety of applications such as automotive and industrial systems, as well as medical equipment. Its unique clamping technique ensures high performance protection and long-term reliability. Its immunity to ESD, lightning, inductive switching and electrical overstress makes it the perfect choice for many high power circuits.
