Overview
The S8040NRP is a Silicon Controlled Rectifier (SCR) manufactured by Littelfuse under the Teccor brand. It features an 800 V rated repetitive off-state voltage and supports a 40 A RMS on-state current. The device operates within a temperature range of -40°C to +125°C and utilizes an SMTO-263-2 surface-mount package. Key electrical characteristics include a maximum holding current of 60 mA, a forward voltage of 1.8 V, and a gate trigger current of 40 mA. It withstands non-repetitive peak currents up to 520 A.
Feature Summary
- Surface-mount construction in an isolated SMTO-263-2 package for automated PCB assembly
- High surge capability with a non-repetitive peak on-state current rating of 520 A
- Robust thermal performance supporting operation up to +125°C junction temperature
Applications
- Industrial motor control circuits
- Solid-state relay implementations
- General-purpose AC power switching applications
Procurement Notes
Verify component authenticity through authorized Littelfuse distributors or certified suppliers. Confirm RoHS compliance status via official documentation before integration. Ensure storage conditions maintain device integrity. Validate part markings against manufacturer specifications to prevent counterfeit infiltration during supply chain acquisition.
Selection Notes
Select this SCR for applications requiring high current handling in a compact surface-mount form factor. Verify that the circuit's peak transient currents remain below the 520 A limit. Ensure the gate drive circuit can supply at least 40 mA to guarantee reliable triggering. Consider the 800 V blocking voltage relative to the system's peak line voltage.
Part Context
This component belongs to the Sxx40x series of Thyristors from Littelfuse. It is designed for general-purpose power control tasks where robustness and high current capacity are required. The SMTO-263-2 package provides efficient heat dissipation compared to smaller surface-mount alternatives.
Replacement Considerations
Cross-reference with other 40A 800V SCRs in the SMTO-263-2 package. Verify pinout compatibility and thermal resistance values. Ensure substitute devices meet the same 520 A surge current requirement and gate trigger specifications.
