Q6040J7TP

Triacs Overview

The Littelfuse Q6040J7TP is a high-power triac designed for robust AC switching applications. It features a 600 V rated repetitive off-state voltage (VDRM) and supports an RMS on-state current 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 operating temperature of +125 °C
• Robust surge handling capability with non-repetitive peak currents up to 400 A
• Sensitive gate drive requirements with a maximum trigger current of 100 mA

Triacs Applications

• Industrial motor speed control systems
• Solid-state relays for AC load switching
• General-purpose AC power regulation circuits

Triacs Procurement Notes

Verify the specific suffix J7TP against official Littelfuse documentation to confirm pinout configuration and isolation ratings. Ensure the procurement channel provides valid RoHS compliance data. Cross-reference the manufacturer part number with authorized distributor listings to validate authenticity and traceability before finalizing orders.

Triacs Selection Notes

Select this component when a 40 A RMS current rating and 600 V blocking voltage are required in an SMTO-218 package. Consider the 100 mA gate trigger current for driver compatibility. Evaluate thermal management needs given the 125 °C junction limit. Compare against the QJ series if higher surge capacity or lower gate sensitivity is needed.

Triacs Part Context

This triac belongs to the Littelfuse Qxx40xx series, which focuses on medium-to-high power thyristor solutions. The Q6040J7TP shares the standard 40 A form factor with variants like the Q6040K7TP, differing primarily in internal gate structure and triggering specifications while maintaining identical voltage and current ratings.

Triacs Replacement Considerations

The Q6040K7TP is a documented alternative within the same series offering similar electrical ratings but potentially different gate characteristics. Verify pinout compatibility and thermal resistance values before substitution.
