Q4006LTTP

Triacs Overview

The Littelfuse Q4006LTTP is a bidirectional triac belonging to the Teccor QxxxxLTx series, designed for AC power control applications. It features a 400V repetitive peak off-state voltage and an RMS on-state current rating of 6A. The device utilizes a TO-220-2 package for thermal management and mounting. Key electrical characteristics include a maximum holding current of 25mA and a gate trigger voltage range of 1.3V to 2.5V. The component exhibits a typical on-state voltage drop of 1.6V at rated current and maintains a low off-state leakage current of 50µA under specified conditions.

Triacs Feature Summary

• Bidirectional switching capability for alternating current circuits
• Integrated thermal design within a standard TO-220-2 housing
• Defined gate sensitivity parameters for reliable triggering

Triacs Applications

• AC motor speed control systems
• Solid-state relay implementations
• Lighting dimmer circuitry

Triacs Procurement Notes

Verify the specific suffix LTTP against official Littelfuse documentation to confirm pinout configuration and packaging type. Ensure the procurement channel provides valid traceability data. Confirm that the delivered components match the exact part number specifications regarding voltage ratings and current handling capabilities before integration into production lines.

Triacs Selection Notes

Select this component when a 400V blocking voltage and 6A continuous current capacity are required in a TO-220-2 form factor. Evaluate the gate trigger requirements against the driver circuit's output capabilities. Consider thermal dissipation needs based on the expected load current and ambient operating temperature conditions during system design.

Triacs Part Context

This triac is part of the Teccor Q series, which focuses on general-purpose AC power switching. The Q4006LTTP variant specifically addresses applications requiring moderate voltage isolation and current handling. It serves as a fundamental semiconductor switch for controlling power delivery in residential and industrial AC loads.

Triacs Replacement Considerations

Cross-reference with other Q4006 variants from Littelfuse or equivalent triacs from other manufacturers offering identical 400V/6A ratings and TO-220-2 packages. Verify pin compatibility and thermal resistance values to ensure direct substitution without circuit modification.
