The SDP series SIDACtor^® protection thyristor from Littelfuse in the SOT23-6 package provides robust overvoltage protection for broadband/xDSL telecommunications equipment with minimal effects on connection speed and reach. Patent-pending silicon crowbar technology allows for 45 percent lower capacitance than clamping devices like transient voltage suppressors (TVSs). It also provides faster response to surges, ensuring lower overshoot voltages and improved electrostatic discharge (ESD), lightning and power fault protection.

• Lowest off-state capacitance crowbarring component on the market
• Repetitive Peak Off-State Voltage (V_DRM) is compatible with a Class H line driver and a high-voltage-level drive capability
• Small-footprint, low-profile SOT23-6 package
• Minimal impact on connection speed and reach
• Lower dynamic resistance and overshoot values than clamping devices, to help prevent xDSL driver chip failures
• Compact package makes it well-suited for high-density card designs
