Overview
The Littelfuse S4016NRP is a Silicon Controlled Rectifier (SCR) from the Teccor Sxx40x series, designed for high-current power control applications. It features a rated repetitive on-state voltage of 400 V and supports a maximum RMS on-state current of 16 A. The device utilizes an SMD/SMT mounting style within an SMTO-263-2 package, ensuring compatibility with automated surface-mount assembly processes. Key electrical characteristics include a forward voltage drop of 1.8 V at rated current, a gate trigger voltage of 1.5 V, and a gate trigger current of 40 mA. It operates reliably across a temperature range from -40°C to +125°C, with a non-repetitive peak on-state current capability of 520 A.
Feature Summary
- Surface-mount construction in an SMTO-263-2 package for automated PCB integration
- High surge current handling capability up to 520 A for robust circuit protection
- Low forward voltage drop of 1.8 V to minimize conduction losses
- Wide operating temperature range suitable for demanding industrial environments
Applications
- AC motor speed control systems
- Solid-state relays and contactors
- Industrial power regulation circuits
Procurement Notes
Verify the specific suffix 'NRP' against the manufacturer's official datasheet to confirm the exact reel packaging quantity and tape-and-reel specifications. Ensure that the SMTO-263-2 footprint matches the target PCB design guidelines. Confirm RoHS compliance status through the latest component certification documents provided by Littelfuse before finalizing procurement orders.
Selection Notes
Select this component when a surface-mount SCR is required for 16 A continuous load applications with 400 V blocking capability. Compare the 40 mA gate trigger current against available drive circuitry to ensure sufficient triggering power. Evaluate the thermal management requirements based on the 1.8 V forward voltage drop and the junction-to-case thermal resistance specified in the datasheet for the chosen ambient conditions.
Part Context
This part belongs to the Littelfuse Teccor Sxx40x family of silicon controlled rectifiers. These devices are engineered for general-purpose power switching tasks. The S4016NRP specifically addresses the need for compact, high-current surface-mount solutions, replacing traditional through-hole packages in modern electronics manufacturing while maintaining equivalent electrical performance standards.
Replacement Considerations
Consult the Littelfuse replacement guide for direct equivalents within the Sxx40x series. Verify pinout compatibility and thermal characteristics when substituting with other manufacturers' SCRs in the SMTO-263-2 package.
