The SMAJ28A 400W Transient Voltage Suppressor (TVS) Diode from RUILON is a high-reliability surge protection device designed to safeguard sensitive electronic circuits from voltage transients, electrostatic discharge (ESD), and switching surges. Packaged in a compact SMA (DO-214AC) form factor, it delivers excellent surge handling capability while supporting efficient surface-mount PCB assembly in modern electronic systems.
The SMAJ28A provides fast response clamping action, ensuring that sudden over-voltage events are quickly suppressed before they can damage critical components such as ICs, microcontrollers, and communication interfaces. With a peak pulse power rating of 400W, it offers strong energy absorption performance suitable for demanding industrial and consumer applications.
Its low leakage current ensures minimal power loss during normal operation, improving system efficiency and stability. The device also features stable breakdown voltage characteristics and high surge endurance, making it highly reliable in environments exposed to repetitive transient stress such as inductive load switching and lightning-induced surges.
Compared to lower-rated protection devices, the SMAJ28A provides enhanced surge capacity and improved durability, making it a dependable solution for long-term circuit protection requirements.
