SMBJ26A-AT 600W 26V TVS Diode SMBJ-AT | RUILON

The SMBJ26A-AT is a 600W transient voltage suppressor (TVS) diode designed to protect sensitive electronic circuits from ESD, lightning-induced surges, and fast voltage transients. With a 26V standoff voltage, it provides effective clamping performance while maintaining stable operation margin for low-voltage power and signal line applications.

Packaged in a compact SMB (DO-214AA) surface-mount format, it is optimized for high-density PCB designs and automated assembly processes. The device features ultra-fast response time, enabling immediate suppression of transient overvoltage events to protect ICs, communication interfaces, and control electronics. Its low leakage current ensures minimal power loss during normal operation, while the glass-passivated junction structure enhances long-term reliability and thermal stability under harsh electrical conditions.

The 26V rating offers increased voltage tolerance, making it suitable for modern electronic systems that require strong surge protection with wider operating margins in industrial, telecom, and consumer applications.
