TVS diodes are voltage dependent devices mainly used to protect sensitive electronic equipment from electrostatic discharge (ESD), lightning and induced surges. P6KE180AHE3/73 is a special two-terminal non-current limiting bidirectional TVS diode that provides transient overvoltage protection. This device has been designed to protect sensitive electronic components from high levels of ESD, lightning and other destructive transients. It is particularly suitable for computer and telecom applications.

The P6KE180AHE3/73 TVS Diode has a device voltage rating of 180V and a power dissipation rating of 73W at tp=8/20μs (IEC-61000-4-5). The P6KE180AHE3/73 features a highly reliable glass passivated junction and provides transient protection up to 2.4kW. This device has low reverse leakage current and it can handle up to 200A peak pulse current. It also has high reliability and low capacitance.

The main application field of this device is for protection of digital integrated circuits against overvoltage transients. It is very useful in applications such as networking, industrial process control, radio, computers, consumer electronics and telecommunications. It is also used in the protection of power supplies, optical receivers, and other delicate and sensitive electronic systems. Its capacitance rating of 0.7pF (Typical) allows for the protection of applications with high data rates.

The working principle of the P6KE180AHE3/73 involves the use of a bidirectional diode connected across the source and load. When a transient voltage occurs on the source or load, the current will flow through the diode and be limited to a safe level. The device is able to clamp much higher transient voltages than traditional zener diodes, allowing for a higher degree of protection. The protection clamping is characterized by a zener-like knee followed by a current limiting plateau.

The P6KE180AHE3/73 TVS diode is an ideal solution for high power overvoltage protection applications. It offers a high degree of protection from overvoltage transients and offers excellent performance. It has a low reverse leakage current and a very low capacitance, making it well suited for high speed data protection. By using this device, the designer can be sure of the highest level of protection for sensitive equipment.
