The TPA240 Thyristor Surge Suppressor from RUILON is a high-reliability transient voltage protection device designed to safeguard sensitive electronic circuits from electrostatic discharge (ESD), lightning surges, and switching transients. Utilizing advanced thyristor-based surge suppression technology, it provides ultra-fast response and precise clamping performance, making it ideal for telecom, industrial, and power protection applications.
With a breakover voltage of approximately 240V, the TPA240 is optimized for low-voltage protection environments requiring stable and rapid surge response. It remains in a high-impedance state during normal operation and quickly 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, allowing 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 stability and long-term reliability.
Packaged in a rugged DO-15 axial form factor, the TPA240 provides excellent mechanical strength and easy through-hole PCB mounting, making it suitable for industrial electronics, power systems, and communication protection designs requiring durable and long-lasting surge suppression.
