TVS - Diodes

A transient voltage suppressor (TVS) diode, also known as a transil diode or transzen diode, is an electronic component which is designed to protect electronic circuits from high voltage transients and surges such as electrostatic discharge (ESD) and voltage spikes, and for other purposes. It is a three-terminal solid-state device consisting of two dedicated electrodes and a common electrode. The two dedicated electrodes are called anode (A) and cathode (K), and the common electrode is usually connected to the circuit’s ground.

The 5KP75-E3/73 TVS diode is a unidirectional device, also known as a spark gap diode, designed for transient voltage protection. This component is designed to protect against voltage transients much higher than its rated voltage and can withstand voltages up to 5.75kV. The 5KP75-E3/73 is a 75A TVS diode with a 600W peak pulse power capability.

Application Field & Working Principle

The 5KP75-E3/73 TVS diode is mainly used in the telecommunications, automotive, and industrial fields. Its main application is for ESD protection, overvoltage protection, and lightning surge protection. It also has other applications in automotive systems, such as in the powertrain, door modules, and control unit protection.

The 5KP75-E3/73 works by limiting the voltage peak to a safe level, reducing the amplitude of a transient pulse through three main steps; breakdown, conduction, and full recovery. When the voltage across the diode reaches the breakdown voltage, it will conduct and current will flow through in a forward direction until the voltage drops below the recovery voltage. After the current stops flowing, the diode will recover to its normal state and is ready to protect the next transient.

The 5KP75-E3/73 TVS diode also exhibits a low capacitance value in the range of 0.03~0.27pF, further reducing transient voltage transients. It also has a fast response time, on the order of 100ps. This component can also be used in automotive systems, as it can withstand the high temperatures that are encountered in these situations.

The 5KP75-E3/73 is a reliable and versatile component that can protect a wide variety of applications against voltage transients and ESD. Its relatively low price, solid performance, and small size make it a popular choice for those who need reliable and easy to use transient voltage protection.
