TVS - Diodes

Transient voltage suppressors (TVSs) are a type of unidirectional semiconductor protection devices which are most commonly used as surge absorbers for protecting vulnerable elements in electronic systems. These surge absorbers are designed to reduce overvoltages of both positive and negative polarities, and they operate by conducting a large amount of current when the voltage reaches a certain threshold. A TVS is an effective and reliable method of providing protection against electrical overstress (EOS) and electrostatic discharge (ESD), which can cause permanent damage to sensitive components in electronic circuits. The P4KE16HE3/73 TVS diode is specifically designed to provide protection against high-voltage, high-frequency pulses in communication and power systems. It is rated at 5000W peak pulse power (tp) at 10/1000 μs waveform, and has an operating voltage range of 5V to 32V. The device is constructed using a low-inductance construction and features a surge current rating of 80A (8/20 μs). The P4KE16HE3/73 is a robust, cost-effective solution for providing protection against transient surges such as lightning strikes, fault currents, and long cable runs. The working principle of the P4KE16HE3/73 is based on the avalanche breakdown effect. When a semiconductor material’s internal electric field reaches a critical value, it will cause a region of the device to break down and rapidly conduct current. This avalanche breakdown effect allows the P4KE16HE3/73 to quickly clamp the voltage to a safe level, in order to protect the components of a circuit from potential damage. The P4KE16HE3/73 is especially well-suited for use in telecommunications and power systems where transient surges can cause significant damage. It has a fast response time (<1ns) which makes it suitable for high-frequency applications. The P4KE16HE3/73 can be used as a protective element in both AC and DC power systems, as well as in telecommunications networks. It is also suitable for protecting sensitive electronic components from electrostatic discharge, which can be caused by user interaction with external system components such as keyboards or display screens. The P4KE16HE3/73 is available in both through-hole and surface mount packages. It is engineered with a low figure of merit (Vf/Ir) of 0.8 V, which ensures that it can absorb high-energy transients without suffering from excessive power losses. The device also supports a wide temperature range and has a low leakage current, making it ideal for use in applications where high levels of reliability and safety are critical. In summary, the P4KE16HE3/73 is an effective and reliable transient voltage suppressor designed specifically for use in telecommunications and power systems. It provides protection against transient surges and electrostatic discharge, and its fast response time and low figure of merit make it a cost-effective solution for providing reliable and efficient protection against damage caused by overvoltages.
