SMDJ36A-AT 3000W 36V TVS Diode SMDJ-AT | RUILON

The SMDJ36A-AT is a 3000W transient voltage suppressor (TVS) diode designed to provide strong protection against electrostatic discharge (ESD), lightning surges, and fast transient voltage spikes. With a 36V standoff voltage, it delivers accurate overvoltage clamping while maintaining stable operation for low- to mid-voltage power rails and signal line applications.

Encapsulated in the SMC (DO-214AB) surface-mount package, the SMDJ-AT series offers significantly higher surge handling capability compared to SMBJ and SMCJ families, making it ideal for circuits exposed to high-energy transient conditions. The device features ultra-fast response time, ensuring immediate suppression of voltage spikes to protect ICs, communication interfaces, and control electronics. Its low leakage current improves system efficiency, while the glass-passivated junction structure ensures excellent long-term reliability and thermal stability under harsh environments.

The 36V rating provides increased operating margin and stable protection performance, making it suitable for modern electronic systems requiring robust surge immunity.
