Q6040K7TP

Triacs Overview

The Littelfuse Q6040K7TP is a bidirectional triac in the Qxx40xx series, designed for high-power switching applications. It features a 600 V rated repetitive off-state voltage (VDRM) and conducts an RMS on-state current (It RMS) of 40 A. The device operates within a temperature range of -40 °C to +125 °C and utilizes an SMTO-218 through-hole package. Key electrical characteristics include a maximum holding current of 120 mA, a gate trigger voltage of 2.5 V, and a gate trigger current of 100 mA. It exhibits a low on-state voltage of 1.8 V and a leakage current of 20 µA at VDRM.

Triacs Feature Summary

• High thermal stability with a maximum junction temperature rating of +125 °C
• Sensitive gate triggering capability with defined voltage and current thresholds
• Robust construction in a standard through-hole SMTO-218 package

Triacs Applications

• Industrial motor speed control systems
• Solid-state relay implementations
• AC power regulation circuits

Triacs Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number Q6040K7TP with official Littelfuse documentation. Confirm that the SMTO-218 package matches design requirements. Ensure compliance with RoHS directives as specified in the datasheet. Validate electrical parameters against application needs before integration.

Triacs Selection Notes

Select this triac when a 600 V blocking voltage and 40 A continuous current capacity are required. The SMTO-218 package suits through-hole PCB layouts. Consider the 100 mA gate trigger current for driver compatibility. Evaluate thermal management strategies given the 125 °C operating limit and 40 A load conditions.

Triacs Part Context

This component belongs to the Littelfuse Qxx40xx series of triacs. The series offers various voltage ratings, including 400 V and 600 V options. All variants share similar current handling capabilities and packaging styles, providing designers with standardized solutions for different voltage isolation requirements in power electronics.

Triacs Replacement Considerations

The Q6040J7TP is a verified alternative within the same series. It shares identical electrical ratings and package dimensions but differs in specific gate sensitivity classifications. Verify pinout compatibility and thermal performance before substitution.
