S6025NTP

Overview

The Littelfuse S6025NTP is a Silicon Controlled Rectifier (SCR) designed for high-power switching applications. It features a rated repetitive peak off-state voltage of 600 V and an RMS on-state current capability of 25 A. The device utilizes a TO-220AB package with three terminals, facilitating through-hole mounting. Key electrical characteristics include a maximum non-repetitive peak surge current of 250 A and a gate trigger current of up to 35 mA. The component operates within a junction temperature range from -40 °C to +125 °C, ensuring reliability in demanding thermal environments.

Feature Summary

• High current handling capacity suitable for industrial power control
• Robust surge current tolerance for transient protection
• Sensitive gate drive requirements for efficient triggering

Applications

• Industrial motor speed control systems
• Solid-state relay circuits
• Power supply regulation modules

Procurement Notes

Verify the specific suffix designation against official Littelfuse documentation to confirm exact pinout and thermal specifications. Ensure that the procurement channel provides genuine components with traceable manufacturing data. Cross-reference the part number with the latest datasheet revisions to confirm compliance with current environmental standards and material declarations before finalizing orders.

Selection Notes

Select this component when a 600 V blocking voltage and 25 A continuous current rating are required in a standard TO-220 form factor. Consider the 250 A surge capability for applications involving inductive loads or high inrush currents. Evaluate the gate trigger parameters to ensure compatibility with the driving circuitry's output capabilities. Verify thermal management requirements based on the specified operating temperature range and package thermal resistance.

Part Context

This SCR belongs to the broader family of Littelfuse thyristor devices engineered for robust power switching. The S6025NTP shares core performance metrics with other variants in the series, differing primarily in packaging options and specific thermal characteristics. It serves as a fundamental building block for high-current AC/DC control applications where reliable latching and high voltage blocking are critical design constraints.

Replacement Considerations

Direct replacements must match the 600 V voltage rating, 25 A current rating, and TO-220 package type. Verify equivalent surge current ratings and gate trigger specifications to ensure circuit compatibility. Consult manufacturer substitution guides for confirmed cross-references.
