Q6015L552

Triacs Overview

The Littelfuse Q6015L552 is a Triac belonging to the Teccor QxxxxLTx series, designed for AC switching and phase control applications. It features an integrated Diac trigger within the package, eliminating the need for external discrete components. The device operates in a TO-220AB (TO-220-2) through-hole package with three pins. Key electrical parameters include a repetitive peak off-state voltage of 600V, an on-state RMS current rating of 15A, and a surge current capability of 200A. Gate triggering requirements specify a maximum gate trigger current of 50mA and a maximum gate trigger voltage of 2V. The device maintains a peak on-state voltage of 1.6V and supports an operating temperature range from -40°C to 125°C.

Triacs Feature Summary

• Integrated Diac trigger mechanism eliminates the requirement for separate discrete Diac components during assembly.
• Electrically isolated TO-220 package provides 2500V rms isolation between leads and mounting surface without additional insulators.
• Glass-passivated junctions ensure long-term device reliability and parameter stability under varying conditions.

Triacs Applications

• AC speed controls
• Temperature modulation controls
• Lighting controls requiring noise immunity

Triacs Procurement Notes

Verify the specific suffix '52' against official Littelfuse documentation to confirm pinout orientation or thermal pad configuration differences compared to standard variants. Ensure the selected distributor sources directly from authorized channels to guarantee component authenticity and traceability. Cross-reference the part number with the latest datasheet revision history to validate any potential design changes or obsolescence notices prior to final procurement decisions.

Triacs Selection Notes

Select this component when designing circuits that require high noise immunity and simplified assembly due to the built-in Diac trigger. The 15A current rating and 600V voltage capability make it suitable for moderate power AC loads. Consider the TO-220 package's thermal dissipation characteristics and the necessity for adequate heatsinking if continuous operation near the 15A limit is expected. Verify that the 50mA gate drive capability aligns with the control circuitry output specifications.

Triacs Part Context

This Triac is part of the Teccor QxxxxLTx family, which specializes in Quadrac devices combining a Triac and Diac. This integration reduces system cost and assembly time by removing the need for external trigger components. The series offers voltage ratings up to 600V and current capacities ranging from 4A to 15A, providing flexibility for various AC switching applications while maintaining robust performance standards.

Triacs Replacement Considerations

Direct substitutes within the same series include Q6015L5TP and Q6015LTHTP. Verify pin compatibility and thermal resistance values before substitution. Other manufacturers may offer equivalent 15A/600V Triacs with integrated triggers, but functional equivalence must be confirmed via detailed datasheet comparison.
