Q6010L555TP

Triacs Overview

The Littelfuse Q6010L555TP is a three-terminal triac belonging to the Qxx10xx series, designed for general-purpose AC power control applications. It features a rated repetitive off-state voltage (VDRM) of 600 V and an RMS on-state current (It RMS) of 10 A. The device operates within a junction temperature range of -40°C to +125°C and utilizes a TO-220-3 through-hole package. Key electrical parameters include a maximum holding current of 50 mA, a gate trigger voltage of 2.5 V, and a gate trigger current ranging from 50 mA to 75 mA. Non-repetitive peak on-state currents are specified at 100 A and 120 A under different conditions, with an on-state voltage of 1.6 V and a leakage current of 50 uA.

Triacs Feature Summary

• High thermal stability supporting operation up to +125°C junction temperature
• Sensitive gate triggering capability for direct microprocessor interface compatibility
• Robust surge handling with defined non-repetitive peak current ratings
• Standardized TO-220-3 leaded package for efficient heat dissipation

Triacs Applications

• Solid-state relays for industrial switching
• Lighting dimmer circuits for residential and commercial use
• Motor speed control systems for small appliances
• Temperature control regulators in heating equipment

Triacs Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number Q6010L555TP with official Littelfuse documentation. Confirm RoHS compliance status and specific packaging details such as tube quantities against current distributor listings. Ensure the supplier provides traceable origin data to mitigate counterfeiting risks during acquisition.

Triacs Selection Notes

Select this component when a 600 V blocking voltage and 10 A continuous current capacity are required in a TO-220-3 form factor. Consider the 50 mA holding current limit for low-load applications and verify that the gate drive circuit can supply the specified 2.5 V trigger voltage. Evaluate thermal management requirements based on the 1.6 V on-state voltage drop at full load.

Triacs Part Context

This triac is part of the Qxx10xx family, which standardizes pinouts and mechanical dimensions across varying voltage and current ratings within the Littelfuse portfolio. The 'Q' designation typically indicates a standard thyristor structure optimized for cost-effective mass production in consumer and industrial electronics. The suffix 'TP' denotes specific tape-and-reel or tube packaging variations offered by the manufacturer.

Triacs Replacement Considerations

Direct replacements must match the 600 V rating, 10 A current capacity, and TO-220-3 package. Verify gate sensitivity characteristics to ensure compatibility with existing drive circuits. Consult Littelfuse datasheets for equivalent parts within the Qxx10xx series or other manufacturers offering identical electrical specifications.
