Overview
The HS4040NAQ3RP is a standard recovery surface mount SCR from Littelfuse, housed in a TO-263 (D2PAK) package. It features a 400 V repetitive off-state voltage and supports a maximum RMS on-state current of 40 A. The device has a surge capability up to 520 A and a maximum average on-state current of 25 A. Gate trigger current ranges from 38 mA to 65 mA, with a maximum on-state voltage drop of 1.8 V. It operates at a maximum junction temperature of 150°C and complies with AEC-Q101 automotive standards.
Feature Summary
- Fast turn-off time for efficient switching
- AEC-Q101 qualified for automotive reliability
- RoHS compliant construction
Applications
- AC switching applications
- Phase control circuits
- Motor speed modulation
- Temperature modulation systems
Procurement Notes
Verify the specific suffix RP indicates the required tape-and-reel packaging configuration against your assembly requirements. Confirm that the TO-263 footprint matches your PCB design constraints. Ensure the 400V rating meets the peak reverse voltage demands of your AC line or load. Validate thermal management capabilities for the 150°C junction limit under expected operating conditions.
Selection Notes
Select this component when high-speed turn-off characteristics are critical for reducing switching losses. The TO-263 package offers a balance between power handling and surface-mount convenience. Consider the 40A RMS rating for continuous loads and the 520A surge capacity for transient protection scenarios requiring robust thyristor performance.
Part Context
This part belongs to the HS4040xAQx series of Teccor brand SCRs designed for high-temperature and low Tq applications. The series provides reliable solid-state switching solutions for demanding environments. The AEC-Q101 qualification ensures suitability for automotive electronics where long-term reliability and thermal stability are mandatory for system safety.
Replacement Considerations
Cross-reference with other AEC-Q101 qualified SCRs in the TO-263 package offering similar 400V ratings. Verify gate trigger current compatibility to ensure proper drive circuit interface. Check if alternative parts meet the same fast turn-off time requirements for phase control efficiency.
