QJ6040KH6TP

Triacs Overview

The QJ6040KH6TP is a high-temperature Alternistor TRIAC manufactured by Littelfuse. It features a peak repetitive off-state voltage of 600 V and an on-state RMS current rating of 40 A. The device utilizes a TO-218AC isolated package for through-hole mounting. Key electrical parameters include a maximum gate trigger voltage of 1.3 V and a maximum gate trigger current of 80 mA. The non-repetitive surge current capacity is 500 A. It operates within a junction temperature range of -40°C to +150°C.

Triacs Feature Summary

• High-temperature operation capability up to 150°C junction temperature
• Isolated flange mount construction for efficient thermal management
• Alternistor design optimized for high dv/dt immunity

Triacs Applications

• Industrial motor control systems
• Solid-state relay applications
• High-temperature power switching circuits

Triacs Procurement Notes

Verify the specific suffix KH6TP against official Littelfuse documentation to confirm the 600V rating and TO-218AC isolation type. Ensure that the ordering information matches the required thermal and electrical specifications for the target application environment. Cross-reference the manufacturer's latest datasheet to confirm compliance with RoHS standards and any recent process change notifications.

Triacs Selection Notes

Select this component when high thermal stability and robust switching performance are required in power electronics. The 40A RMS current and 600V blocking voltage suit medium-power industrial loads. Consider the TO-218AC package for direct heatsink mounting. Verify that the gate trigger requirements align with the driving circuit capabilities, noting the 80mA maximum gate current specification.

Triacs Part Context

This part belongs to the QJxx40xx series of high-temperature TRIACs from Littelfuse. These devices are designed as Alternistors, offering superior performance in harsh environments compared to standard TRIACs. The series provides reliable switching for AC power control applications where elevated temperatures and high di/dt stresses are present.

Triacs Replacement Considerations

Consult Littelfuse official substitution guides for verified equivalents. Generic replacements may not match the specific 150°C thermal rating or the isolated TO-218AC package characteristics. Ensure any substitute maintains the 600V VDRM and 40A IT(RMS) ratings.
