Overview
The HS4040NAQRP is an automotive-grade Silicon Controlled Rectifier (SCR) from Littelfuse, designed for high-reliability applications. It features a rated repetitive off-state voltage of 400V and an on-state RMS current of 40A. The device is qualified to AEC-Q101 standards, ensuring robust performance in harsh environments. It utilizes a surface-mount TO-263 (D2PAK) package, facilitating automated assembly and compact circuit design. Key electrical parameters include a maximum gate trigger voltage of 1.5V and a holding current of 60mA, supporting efficient control in solid-state switching scenarios.
Feature Summary
- Automotive qualification compliant with AEC-Q101 standards for enhanced reliability
- Surface-mount TO-263 (D2PAK) package for space-efficient PCB integration
- High thermal stability suitable for demanding industrial and automotive environments
Applications
- Solid-state relays in automotive systems
- Industrial motor control circuits
- Power supply phase control modules
Procurement Notes
Verify the specific suffix 'QRP' confirms the AEC-Q101 automotive qualification and D2PAK surface-mount packaging configuration. Ensure the procurement order explicitly references the full part number HS4040NAQRP to distinguish it from non-automotive or through-hole variants within the same series. Confirm that the supplier provides documentation validating the AEC-Q101 compliance status required for automotive manufacturing processes.
Selection Notes
Select this component when an SCR requires both high current handling capacity and strict automotive reliability standards. The surface-mount form factor is critical for designs prioritizing board space reduction and automated placement. Consider the 400V blocking capability and 40A continuous rating against the specific load requirements of the application to ensure adequate safety margins during operation.
Part Context
This device belongs to the Teccor® series of SCRs, specifically tailored for automotive and industrial markets. It represents a shift from traditional through-hole thyristors to surface-mount solutions without compromising power handling capabilities. The inclusion of AEC-Q101 certification places it within a subset of components approved for use in vehicle electronic systems requiring stringent quality and durability testing.
Replacement Considerations
Direct substitutes must match the 400V/40A rating, TO-263 package, and AEC-Q101 qualification. Verify pinout compatibility and thermal characteristics before swapping.
