SMAJ28-E3/61 Application Field and Working Principle

Transient Voltage Suppressor (TVS) diodes are devices used to protect electronic circuits from undesired electrical transients commonly caused by electrostatic discharge or lightning. The SMAJ28-E3/61 is an unidirectional protection diode that provides an extremely low breakdown voltage. This TVS diode is used primarily for the protection of low-voltage electronic components from transients caused by overvoltage events, such as electrostatic discharge (ESD). The SMAJ28-E3/61 is part of a larger family of TVS diodes made by Littelfuse–a major manufacturer of Overvoltage Protection (OVP) products. These devices are available in a variety of packages and are designed for a wide range of applications, including automobiles, industrial, and consumer products. The SMAJ28-E3/61 is an axial-lead, unidirectional, Transient Voltage Suppressor diode. It has a working voltage of 28V and a maximum breakdown voltage of 61V. This device is RoHS compliant and can withstand high temperature operating conditions of up to 175°C. In addition, the device features an extremely fast response time and can provide precise overvoltage protection in a wide range of applications. The SMAJ28-E3/61 is designed to protect low voltage circuits such as microcontrollers, solid-state relays, FPGAs, sensors, and other low voltage ICs from voltage transients caused by ESD or lightning. Additionally, it can be used for protecting I/O interfaces and modems in equipment with integrated circuit cards. The device is also designed with an internal clamp voltage that prevents Extremely Low voltage (ELV) conditions from damaging sensitive elements. With its low figure of merit and fast response time, the device ensures a high degree of ESD and EMC protection. The SMAJ28-E3/61 is designed to protect sensitive components and circuits from voltage transients. The device works by providing a low impedance path for any voltage transients and their related current spikes. When the voltage transient occurs, the diode activates and clamps the voltage within a safe operating range, thus protecting the circuit. The SMAJ28-E3/61 is a reliable and highly efficient solution for protecting sensitive components and circuits from transient overvoltage. It is designed to provide precise overvoltage protection in a variety of applications and its low figure of merit ensures a high degree of ESD and EMC protection. In addition, the device has a fast response time and is RoHS compliant, making it an ideal solution for high reliability applications.
