TVS - Diodes: 1.5KE18-E3/54 Application Field & Working PrincipleOne of the most important components in any electrical system is the Transient Voltage Suppression (TVS) Diode. Over the years, these diodes have become increasingly popular in the world of electronics, thanks to their ability to protect electrical systems from voltage spikes, current surges, and other power and performance issues.The 1.5KE18-E3/54 is a type of TVS diode, and it\'s commonly used in automotive applications. In this article, we\'ll discuss the 1.5KE18-E3/54 and its application field and working principle.Application Field The 1.5KE18-E3/54 is a bidirectional, high-voltage, high-speed diode. It is designed to protect electronic devices from damage due to transient surges in voltage. It is commonly used in automotive applications such as a surge protector for vehicle on-board computers and alternators, engine controls, and other electronic components. It can also be used in EV/HEV systems. Working PrincipleThe 1.5KE18-E3/54 diode works by providing a voltage emission path for transient surge protection. When an electrical surge occurs, the diode will conduct the surge current away from the system.It is composed of a positive electrode and a negative electrode. When the surge voltage exceeds the breakdown voltage, electrons flow through the diode from the negative to the positive electrode. This process of allowing electrons to flow through the diode from negative to positive is known as avalanche breakdown and it results in a surge of current being conducted away from the system.The 1.5KE18-E3/54 is designed to self-reset, and once the voltage is normalized it will switch back to its non-conductive state. This diode can withstand continuous high-energy transients and will provide protection against damaging current spikes.ConclusionThe 1.5KE18-E3/54 is a bidirectional, high-voltage, high-speed diode designed for transient surge protection. It is commonly used in automotive applications to protect computers, alternators, and other components from voltage spikes and current surges. It works by providing a voltage emission path for transient surge protection, allowing for the flow of electrons from the negative to the positive electrode. The 1.5KE18-E3/54 is designed to self-reset and provide protection against damaging current spikes.
