SMDJ16A-AT 3000W 16V TVS Diode SMDJ-AT | RUILON

The SMDJ16A-AT is a 3000W transient voltage suppressor (TVS) diode designed to provide high-reliability protection against electrostatic discharge (ESD), lightning surges, and fast transient voltage spikes. With a 16V standoff voltage, it ensures precise and stable overvoltage clamping for low-voltage power rails and signal line applications.

Encapsulated in the SMC (DO-214AB) surface-mount package, the SMDJ-AT series delivers superior surge handling capability compared to lower power TVS families such as SMBJ and SMCJ, making it ideal for circuits exposed to high-energy transients. The device features ultra-fast response time, enabling immediate suppression of transient events to protect ICs, communication interfaces, and control electronics. Its low leakage current enhances system efficiency, while the glass-passivated junction structure ensures excellent long-term reliability and thermal stability in demanding environments.

The 16V rating provides improved operating margin compared to lower-voltage devices, making it suitable for modern electronic systems requiring robust and efficient surge protection.
