SMFJ18A TVS Diode SOD-123 200W | 18V Surge Protection | RUILON

The SMFJ18A TVS Diode from RUILON is a high-performance 200W transient voltage suppressor designed to protect electronic circuits from voltage spikes, lightning surges, and electrostatic discharge (ESD). With an 18V reverse standoff voltage, it is well-suited for low to medium voltage applications that require stable operation and dependable overvoltage protection.

Built using advanced avalanche technology, the SMFJ18A delivers ultra-fast response time, low leakage current, and precise clamping characteristics. Its higher voltage rating compared to lower series variants enhances tolerance to normal voltage fluctuations, reducing false triggering while maintaining strong transient suppression performance.

Housed in a compact SOD-123 surface-mount package, this diode is optimized for space-constrained PCB layouts and high-density circuit designs. It offers efficient thermal performance and consistent operation under repeated surge conditions. Designed for durability, the SMFJ18A ensures long service life and reliable protection across a wide range of electronic applications.
