TVS - Diodes

TVS (Transient Voltage Suppression) diodes are vital components used to protect electronic devices from surge and ESD (electrostatic discharge). Generally, they come in the form of an axial or surface mount and are designed to protect against a wide range of voltage events. The SMAJ28CHE3/5A is a commonly used single-line transient voltage suppressor (TVS) diode intended to protect sensitive electronic components from voltage overshoots caused by transient voltage events. Its main features include low clamped voltage, low leakage current and high peak surge current ratings.

The SMAJ28CHE3/5A TVS diode is designed for use in a variety of applications. These applications include power line protection, telecommunications systems, automotive electronics, circuit board protection and any device susceptible to overvoltage due to lightning movement or power cross. The SMAJ28CHE3/5A diode is available in an axial package with two terminals and its limiter voltage is 28V. The working principle of this diode is based on a junction barrier of the p-type and n-type semiconductors. When a current passes through the diode at a level exceeded by the breakdown voltage, it starts conducting and limits the flow of current. This limits the voltage, thus preventing damage to the surrounding equipment.

This diode also features a fast response time; it can limit the voltage within a few nanoseconds, meaning it can protect devices against lightning strikes. The SMAJ28CHE3/5A diode is equipped with ESD protection, making it suitable for protecting computers and other sensitive devices against electrostatic shocks. Unlike other diodes, the SMAJ28CHE3/5A can handle high pulse currents without the risk of failure, and is also highly stable Across a wide range of temperatures (-55°C to +150°C).

The SMAJ28CHE3/5A TVS diode can be used in a wide variety of applications due to its features of low clamped voltage, low leakage current, high peak surge current and reliability across a wide range of temperatures. It is capable of protecting devices from electrostatic discharge, overvoltage and lightning surge events. This diode provides reliable protection of sensitive electronic devices against voltage overshoots, thereby minimizing the risk of component failure.
