Overview
The Littelfuse S8040NTP is a Silicon Controlled Rectifier (SCR) from the Teccor Sxx40x series, designed for surface mount applications in the SMTO-263-2 package. It features an RMS on-state current of 40 A and a rated repetitive off-state voltage of 800 V. The device has a maximum non-repetitive peak on-state current of 520 A and a holding current of up to 60 mA. Electrical characteristics include a forward voltage of 1.8 V, a gate trigger voltage of 1.5 V, and a gate trigger current of 40 mA. It operates within a temperature range of -40°C to +125°C.
Feature Summary
- Surface Mount Design: Utilizes the SMTO-263-2 package for automated PCB assembly.
- High Voltage Blocking: Rated for 800 V repetitive off-state voltage.
- Robust Surge Handling: Supports high non-repetitive peak currents for transient protection.
Applications
- Industrial motor control circuits
- Solid state relay modules
- AC power switching systems
Procurement Notes
Verify component authenticity by checking manufacturer markings against official datasheets. Confirm RoHS compliance status via Littelfuse documentation. Ensure storage conditions maintain integrity before soldering. Validate package type matches design requirements.
Selection Notes
Select this SCR based on its 40 A RMS current capacity and 800 V blocking voltage. Consider the SMTO-263-2 package for space-constrained surface mount designs. Evaluate thermal management needs given the 125°C maximum operating temperature limit.
Part Context
The S8040NTP belongs to the Teccor Sxx40x family of thyristors manufactured by Littelfuse. This series provides standardized performance for general-purpose power control applications requiring reliable switching capabilities in compact form factors.
Replacement Considerations
Consult Littelfuse official substitution guides for verified equivalents. Cross-reference electrical parameters such as voltage ratings and current capacities when evaluating alternative components.
