The P3500LB Thyristor Surge Suppressor from RUILON is a high-reliability transient voltage protection device designed to protect sensitive electronic circuits from electrostatic discharge (ESD), lightning surges, and switching transients. Based on advanced thyristor surge suppression technology, it delivers ultra-fast response and precise clamping performance, making it suitable for telecom, industrial, and high-voltage protection applications.
With a breakover voltage of approximately 3500V, the P3500LB is optimized for high-voltage protection environments requiring stable and fast surge response. It remains in a high-impedance state under normal operating conditions and rapidly switches to a low-impedance conduction state during surge events, effectively diverting excess transient energy away from sensitive circuitry.
The device offers strong surge current capability, enabling it to withstand high-energy transient events such as lightning-induced surges and inductive switching spikes. Its low on-state voltage helps reduce power dissipation during conduction, improving thermal performance and long-term system reliability.
Encased in a compact SMBF surface-mount package, the P3500LB provides excellent PCB space savings, strong mechanical stability, and easy automated assembly, making it ideal for modern high-density circuit designs requiring robust surge protection.
