SMDJ30A 30V 3000W TVS Diode SMC/DO-214AB RUILON

RUILON

The RUILON SMDJ30A is a high-performance 3000W Transient Voltage Suppressor (TVS) diode designed in the robust SMC/DO-214AB package, delivering reliable protection against high-energy transient voltage events. It is engineered to safeguard sensitive electronic circuits from damage caused by lightning surges, inductive switching spikes, and electrostatic discharge (ESD), ensuring stable and long-term system operation.

With a 30V standoff voltage, the SMDJ30A is optimized for low-voltage DC power rails and signal line protection in industrial, automotive, and communication systems. It provides ultra-fast response time and excellent clamping capability, effectively limiting overvoltage spikes before they can damage critical downstream components. The device supports a peak pulse power dissipation of 3000W (10/1000µs waveform), enabling it to absorb strong transient energy while maintaining stable electrical performance and high reliability.

Compared to lower-voltage TVS diode variants, the SMDJ30A offers a higher operating margin, making it suitable for systems operating at higher nominal DC voltages or environments with wide voltage fluctuations. The SMC package ensures strong mechanical durability, efficient heat dissipation, and compatibility with automated PCB assembly, supporting compact and high-density circuit designs.
