HS4040RAQ3TP

Scrs Overview

The HS4040RAQ3TP is a standard recovery silicon controlled rectifier (SCR) manufactured by Littelfuse Inc. It features a rated repetitive off-state voltage of 400 V and an on-state RMS current of 40 A. The device supports a surge current capability of up to 520 A and operates within a junction temperature range of -40°C to +150°C. Packaged in a TO-220AB through-hole configuration, it is fully compliant with the AEC-Q101 automotive qualification standard.

Scrs Feature Summary

• AEC-Q101 qualified for automotive reliability standards
• Standard recovery characteristics suitable for general switching applications
• High surge current handling capability

Scrs Applications

• Automotive power control circuits
• AC motor speed regulation
• Phase control applications

Scrs Procurement Notes

Verify the specific suffix 'TP' against the official Littelfuse datasheet to confirm package type and tape/reel specifications. Ensure the selected variant meets the required AEC-Q101 compliance level if used in automotive environments. Cross-reference the 400V rating and 40A current capacity with the circuit design requirements before procurement.

Scrs Selection Notes

Select this component when a robust SCR with automotive-grade reliability is required for AC switching or phase control. The 400V blocking voltage and 40A continuous current rating define its operational limits. Consider the TO-220AB package for thermal management needs and through-hole mounting constraints in the target assembly.

Scrs Part Context

This part belongs to the Low Power SCR series from Littelfuse, designed for voltages up to 1200V. The Qxx40xx series designation indicates a 40 Amp bi-directional solid state switch family, although this specific item is an SCR. The series emphasizes high surge capability and compatibility with automotive electronic systems.

Scrs Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical ratings with alternative SCRs from Littelfuse or other manufacturers if direct substitution is necessary.
