Additional Details

The P250L20W SIDACtor device offers a robust clamping voltage, ensuring that sensitive circuits are protected from voltage spikes. Its low capacitance is critical in high-speed data communication lines, as it minimizes signal distortion. The device is designed to quickly switch to an on-state when the voltage exceeds the breakover voltage, diverting the surge current away from the protected circuitry. The Littelfuse SIDACtor technology provides a reliable alternative to other protection devices such as gas discharge tubes (GDTs) and transient voltage suppression (TVS) diodes.
