TVS - Diodes

Transient Voltage Suppression Diodes (TVS-Diodes) are a type of semiconductor device used to protect connected systems from electrical overload and short-circuit conditions. They are designed to absorb and steer excessive transient voltage away from the protected system. 3KASMC18AHE3/57T is a specific type of TVS-Diode from the wide range available that has its own unique working principles and application fields. An important application for TVS-Diodes is surge suppression in the automobile market. Due to the increase in placing ECUs and other electronic components in modern cars, there is a significant risk of spike voltages damaging the entire network. For this reason, TVS-Diodes can be found in various locations inside the car. In particular, the 3KASMC18AHE3/57T is used for overvoltage protection in various automotive applications, such as airbag systems, transmission control systems and emergency warning systems.The working principle behind the 3KASMC18AHE3/57T is based on the breakdown of the PN diode circuit in order to redirect the excessive current away from the protected circuits. As surges of voltage above a certain threshold occur, the device enters a breakdown state, becoming an efficient conductor that redirects the surge current away. This breakdown state stops once the current level is lowered and the diode reverts back to its original non-conducting state.In terms of physical characteristics, the 3KASMC18AHE3/57T is a twoterminal overvoltage control diode that is available in a SOT-23 plastic package. It has a Repetitive peak overvoltage rating (ROV) of 57V, and it also features Low Clamping Voltage and high robustness against thermal shock.In summary, the 3KASMC18AHE3/57T TVS-Diode is a highlyefficient device that can be used to protect systems from electrical overload and surge voltages. In particular, this device offers excellent performance in automotive applications, due to its high robustness and low clamping voltage capabilities. The working principle behind it is based on the breakdown of the PN diode circuit, which redirects the excessive current away and reverts back to its non-conducting state once the current is lowered.
