Q4015L5TP

Triacs Overview

The Littelfuse Q4015L5TP is a Teccor brand bidirectional triac designed for AC power control applications. It features a 400 V rated repetitive off-state voltage and conducts an RMS on-state current of 15 A. The device operates within a temperature range of -40°C to +125°C and utilizes a TO-220-2 through-hole package. Key electrical characteristics include a maximum holding current of 70 mA, a gate trigger voltage of 2.5 V, and a gate trigger current of 50 mA. Non-repetitive peak on-state currents are specified at 167 A and 200 A under different conditions, with an on-state voltage of 1.6 V.

Triacs Feature Summary

• Bidirectional switching capability for alternating current circuits
• High thermal stability supporting operation up to 125°C
• Robust surge handling with defined non-repetitive peak current ratings

Triacs Applications

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

Triacs Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Littelfuse or authorized distributors before integration. Confirm that the TO-220-2 package dimensions match the target PCB footprint requirements. Ensure thermal management solutions account for the 15 A RMS rating and junction temperature limits during high-load operations.

Triacs Selection Notes

Select this component when a 400 V blocking voltage and 15 A continuous current capacity are required in a standard through-hole configuration. Evaluate the 50 mA gate trigger current against the driving circuit's output capabilities to ensure reliable turn-on. Consider the TO-220-2 package for its thermal dissipation properties relative to smaller surface-mount alternatives.

Triacs Part Context

This part belongs to the Littelfuse Teccor Qxx15xx series of triacs. The series is engineered for general-purpose AC power switching. The Q4015L5TP specifically denotes the 400 V voltage class and 15 A current rating within this family of thyristors.

Triacs Replacement Considerations

Consult official Littelfuse substitution guides for verified equivalents. Cross-reference parameters such as VDRM, IT(RMS), and package type when evaluating alternative manufacturers' components.
