Q6025R667

Triacs Overview

The Littelfuse Q6025R667 is a bidirectional triac designed for AC power control applications. It features a rated RMS on-state current of 25 A and a repetitive peak off-state voltage of 600 V. The device operates within a junction temperature range of -40°C to +125°C and utilizes a TO-220-2 through-hole package. Key electrical characteristics include a gate trigger current of 80 mA, a holding current maximum of 100 mA, and an on-state voltage of 1.8 V. Non-repetitive peak on-state currents are specified at 208 A and 250 A under different pulse conditions.

Triacs Feature Summary

• Bidirectional switching capability for alternating current circuits
• High thermal stability with 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 output stages
• Lighting dimmer circuits

Triacs Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm the part number suffix matches the exact electrical parameters required. Inspect leads for damage and ensure the TO-220-2 package dimensions align with design constraints. Validate RoHS compliance status through current documentation as product status may change.

Triacs Selection Notes

Select this component when a 25 A RMS current rating and 600 V blocking voltage are required in a through-hole configuration. Ensure the driving circuit can supply the specified 80 mA gate trigger current. Verify that the thermal management solution supports the 125°C maximum junction temperature limit during continuous operation.

Triacs Part Context

This device belongs to the Qxx25xx series of triacs from Littelfuse. The series provides standardized high-current solutions for industrial and consumer AC power control. The Q6025R667 variant specifically offers 600 V blocking capability within the 25 A current class.

Triacs Replacement Considerations

The Littelfuse Q6025R667 is listed as obsolete. The Q6025R6TP is identified as a potential replacement option. Verify pinout compatibility and electrical parameter equivalence before substitution.
