TVS - Diodes

A transient voltage suppression (TVS) diode, also known as a surge-suppressor diode, is a device used to protect sensitive electronic components from harmful voltage spikes and other forms of electrical overstress. It is an important part of any modern circuit design and a key component in systems that must survive periods of overvoltage, including automotive, industrial, and telecommunications applications. The P4KE11CA-E3/73 is a TVS diode from the P4KE series manufactured by Formosa Advanced Technologies. This series is optimized for the protection of data and signal lines in industrial and telecom applications, offering higher power handling capability than traditional solutions.

Features and Benefits

The P4KE11CA-E3/73 offers a wide range of features and benefits that make it ideal for industrial and telecom applications. It has a high peak power rating of 2,400 watts, a low clamping voltage of 36 volts, and an ultra-low response time of less than one nanosecond. It also offers a low capacitance of less than 100 pF between each pin, minimizing its effect on the circuit\'s operation and signal integrity. In addition, the P4KE11CA-E3/73 offers a wide temperature range of -65°C to 150°C, enabling it to operate in extreme conditions.

Application Fields

The P4KE11CA-E3/73 is primarily used in data and signal line protection applications, such as those found in industrial and telecom applications. It can also be used in automotive, military, aerospace, and consumer electronics applications.

Working Principle

TVS diodes work by clamping the voltage that passes through them to a safe level when a voltage spike occurs. When the reverse bias voltage reaches the avalanche voltage of the diode, it begins to conduct, reducing the voltage across the circuit and protecting the device from overvoltage. The P4KE11CA-E3/73 uses a Zener diode combined with a parallel Avalanche diode to provide added protection and higher clamping voltages.

Conclusion

The P4KE11CA-E3/73 is an ideal solution for data and signal line protection in industrial and telecom applications. It offers a high peak power rating, a low clamping voltage, and an ultra-low response time. It is also capable of operating in extreme temperatures and offers a low capacitance, making it an excellent choice for applications that require reliable protection.
