HS4040RAQTP

Overview

The HS4040RAQTP is a standard recovery silicon controlled rectifier (SCR) from Littelfuse, designed for automotive applications. It features a 400V off-state voltage rating and a 40A on-state current capability. The device operates within a junction temperature range of -40°C to 150°C. It is AEC-Q101 qualified and housed in a TO-220AB package.

Feature Summary

Automotive-grade reliability with AEC-Q101 qualification
Standard recovery characteristics for efficient switching
Robust thermal performance supporting high junction temperatures

Applications

Automotive embedded electronics systems
Industrial equipment power control
OEM production circuits requiring high surge capability

Procurement Notes

Verify the specific ordering suffix to ensure the correct package variant and compliance status. Confirm that the supplier provides official Littelfuse documentation to validate the AEC-Q101 certification. Check lead times as automotive components may have extended availability periods. Ensure storage conditions meet semiconductor standards to prevent degradation prior to assembly.

Selection Notes

Select this component when automotive-grade SCR performance is required for high-current switching. The 400V rating suits low-voltage DC distribution networks. Consider the TO-220AB package for through-hole mounting and heat dissipation needs. Validate compatibility with gate trigger requirements against system design specifications before integration.

Part Context

This part belongs to the Teccor series of SCRs by Littelfuse. It is engineered specifically for the automotive sector, ensuring durability under harsh environmental conditions. The product line emphasizes safe and efficient electrical energy transfer solutions for modern vehicle architectures.

Replacement Considerations

Check Littelfuse datasheets for direct cross-references within the HS4040 series. Verify pinout compatibility and thermal resistance values if substituting with other manufacturers' parts. Ensure any alternative meets AEC-Q101 standards for automotive use.
