TVS (transient voltage suppressor) diodes have a variety of applications and can be used to regulate, reduce, or protect the voltage of electronic Systems against overvoltage or short-circuit currents. The P4KE100CA-E3/73 is a low capacitance transient voltage suppressor made by Littelfuse, suitable for use in high-speed data lines.

The P4KE100CA-E3/73 is commonly used in high-speed data transmission systems, such as HDMI, Thunderbolt, Firewire, and USB 3.0. It can be used in situations where the voltage of the data transmission line needs to be regulated or controlled, such as in power over Ethernet. It can also be used in circuit protection applications, where it can protect the system from voltage spikes caused by lightning or power outages.

The P4KE100CA-E3/73 has an excellent clamping performance, with a maximum peak pulse current of 100A and a maximum clamping voltage of 13.1V. It is also low capacitance, with a typical capacitance of 0.3 pF, so it does not significantly affect the data signal. It also has a low operating voltage, and is rated for operation up to 10V, which further improves its compatibility with high-speed data transmission systems.

The working principle of the P4KE100CA-E3/73 is fairly simple. It acts as an electrical shunt, diverting surplus electrical current away from the system and into a safe path. When a voltage spike occurs, the diode conducts a current from the main power supply to a safety ground. This reduces the voltage at the supply source, protecting your system from damage.

The P4KE100CA-E3/73 is easy to install and use, and is an effective way of protecting your system from transient voltage spikes. It is also compact and lightweight, making it ideal for use in a wide range of applications. It is available from a variety of distributors, and can be easily found online.
