SMBJ160A-AT 600W 160V TVS Diode SMBJ-AT | RUILON

The SMBJ160A-AT is a 600W transient voltage suppressor (TVS) diode designed to protect electronic circuits from electrostatic discharge (ESD), lightning-induced surges, and fast transient voltage spikes. With a 160V standoff voltage, it provides reliable overvoltage clamping while maintaining stable operation for higher-voltage power and signal line applications.

Housed in a compact SMB (DO-214AA) surface-mount package, it is optimized for high-density PCB layouts and automated assembly processes. The device features ultra-fast response time, ensuring immediate suppression of transient events to safeguard ICs, communication interfaces, and control electronics. Its low leakage current minimizes power loss during normal operation, while the glass-passivated junction structure ensures strong long-term reliability and thermal stability under demanding electrical conditions.

The 160V rating offers higher voltage tolerance, making it suitable for modern electronic systems that require robust surge protection with wide operating margins across industrial, telecom, and consumer electronics environments.
