SMFJ40A TVS Diode SOD-123 200W | 40V Surge Protection | RUILON

The SMFJ40A TVS Diode from RUILON is a high-reliability 200W transient voltage suppressor designed to protect electronic circuits from voltage spikes, lightning surges, and electrostatic discharge (ESD). With a 40V reverse standoff voltage, it is well-suited for low to medium voltage applications that require stable operation and strong overvoltage protection.

Engineered using advanced avalanche technology, the SMFJ40A provides ultra-fast response time, low leakage current, and precise clamping performance. Its higher voltage rating compared to lower series variants enhances tolerance to normal voltage fluctuations, reducing false triggering while ensuring effective transient suppression.

Housed in a compact SOD-123 surface-mount package, this diode is ideal for space-constrained PCB layouts and high-density circuit designs. It offers efficient thermal performance and consistent protection under repetitive surge conditions. Built for durability, the SMFJ40A ensures long service life and dependable operation in demanding electronic environments.
