Q6040K5TP

Triacs Overview

The Littelfuse Q6040K5TP is a standard TRIAC belonging to the Qxx40xx series, designed for high-power AC switching applications. It features a 600 V rated repetitive off-state voltage and conducts a continuous RMS on-state current of 40 A. The device utilizes an isolated TO-218AC (TO-220AB) through-hole package, providing electrical isolation between the main terminals and the mounting base. Key electrical characteristics include a maximum gate trigger voltage of 1.3 V and a gate trigger current of 50 mA. It operates within a junction temperature range of -40°C to +125°C.

Triacs Feature Summary

• Isolated construction allows direct mounting to heatsinks without additional insulating hardware
• High surge capability supports inductive load switching requirements
• Standardized TO-218AC package facilitates automated assembly and thermal management

Triacs Applications

• Industrial motor speed control systems
• Solid-state relay modules
• Lighting dimmer circuits

Triacs Procurement Notes

Verify the specific suffix K5 against official Littelfuse documentation to confirm pinout configuration and isolation specifications. Ensure the procurement source provides valid traceability data. Confirm RoHS compliance status directly from the manufacturer's latest release notes prior to finalizing orders.

Triacs Selection Notes

Select this component when a 600 V rating and 40 A continuous current capacity are required. The isolated package is suitable for designs needing galvanic separation between the control circuit and the power stage. Verify that the gate drive circuit can supply at least 50 mA to ensure reliable triggering under all operating conditions.

Triacs Part Context

This part belongs to the Qxx40xx family of TRIACs from Littelfuse. These devices are engineered for robust performance in industrial environments. The Q6040K5TP shares core electrical parameters with other variants in the series but differs in packaging or specific gate sensitivity configurations defined by the manufacturer.

Triacs Replacement Considerations

Direct replacements must match the 600 V / 40 A specification and isolated TO-218AC package. Verify pin compatibility before substitution. Consult Littelfuse application notes for equivalent part numbers if exact matches are unavailable.
