TPA220 Thyristor Surge Suppressor DO-15 | High-Speed Transient Voltage Protection Device | RUILON

RUILON

The TPA220 Thyristor Surge Suppressor from RUILON is a high-performance transient voltage protection device designed to safeguard sensitive electronic circuits from electrostatic discharge (ESD), lightning surges, and switching transients. Built on advanced thyristor-based surge suppression technology, it offers ultra-fast response and precise clamping behavior, making it ideal for telecom, industrial, and power system protection applications.

With a breakover voltage of approximately 220V, the TPA220 is optimized for low-voltage protection environments requiring stable and fast surge response. Under normal operating conditions, it remains in a high-impedance state, and when a surge event occurs, it rapidly switches to a low-impedance conduction state to safely divert excessive transient energy away from protected circuitry.

The device provides 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 reduces power dissipation during conduction, enhancing thermal performance and long-term system reliability.

Packaged in a robust DO-15 axial form factor, the TPA220 ensures excellent mechanical durability and easy through-hole PCB mounting, making it suitable for industrial electronics and power protection designs requiring rugged and dependable performance.
