Overview
The Littelfuse S2040NRP is a Silicon Controlled Rectifier (SCR) from the Teccor Sxx40x series, designed for surface-mount applications in the SMTO-263-2 package. It features a rated repetitive off-state voltage (VDRM) of 200 V and an on-state RMS current (It RMS) of 40 A. The device supports a maximum non-repetitive peak on-state current of 520 A with a forward voltage drop (Vf) of 1.8 V. Gate triggering requires a maximum voltage (Vgt) of 1.5 V and current (Igt) of 40 mA. Leakage current at VDRM is limited to 10 uA, while holding current (Ih) max is 60 mA. Operating temperature ranges from -40 C to +125 C.
Feature Summary
- Surface-mount construction in SMTO-263-2 package for automated PCB assembly
- High surge current capability with 520 A non-repetitive peak rating
- Low gate trigger requirements for efficient control circuitry
Applications
- AC power control circuits
- Solid-state relays
- Motor speed control systems
Procurement Notes
Verify component authenticity by cross-referencing the manufacturer part number S2040NRP with official Littelfuse documentation. Confirm the specific suffix 'NRP' matches the required reel or cut tape packaging format. Ensure the procurement source provides valid traceability records consistent with the Teccor brand specifications.
Selection Notes
Select this SCR when a 200 V blocking voltage and 40 A continuous current are required in a compact surface-mount form factor. The SMTO-263-2 package facilitates thermal management for moderate power levels. Verify that the gate drive circuit can supply the specified 40 mA trigger current reliably across the full operating temperature range.
Part Context
This component belongs to the Littelfuse Teccor Sxx40x series of thyristors. The series offers various voltage ratings within the same physical footprint, allowing designers to standardize board layouts while adjusting voltage capabilities. The S2040NRP specifically provides the 200 V option within this standardized surface-mount family.
Replacement Considerations
Direct replacements must match the 40 A RMS current, 200 V VDRM, and SMTO-263-2 package. Verify pinout compatibility and thermal resistance characteristics before substituting with other manufacturers' SCRs.
