Q6025L659

Triacs Overview

The Q6025L659 is an Alternistor TRIAC manufactured by Littelfuse, designed for high-reliability AC switching applications. It features a blocking voltage rating of 600V V(DRM) and supports an RMS on-state current of 25A I(T)RMS. The device is housed in an isolated TO-220AB package with three pins, ensuring electrical isolation between the leads and the mounting surface. Key electrical parameters include a critical rate of rise of off-state voltage (dv/dt) of 600 V/us and a minimum commutating dv/dt of 30 V/us. The maximum DC gate trigger current is specified at 80 mA, with a maximum DC gate trigger voltage of 1.3 V. The component complies with RoHS standards.

Triacs Feature Summary

• Alternistor technology eliminates the need for external snubber networks
• Electrically isolated TO-220AB package removes requirement for separate insulators
• Glass-passivated junctions ensure long-term parameter stability and reliability

Triacs Applications

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

Triacs Procurement Notes

Verify the specific suffix '59' against official Littelfuse documentation to confirm exact pinout or marking variations. Ensure the selected variant matches the required isolation voltage and thermal management specifications for the target application environment.

Triacs Selection Notes

Select this component for applications requiring robust AC phase control without snubber circuits. The 25A current rating and 600V blocking voltage suit industrial loads. Confirm that the gate drive circuit can supply the maximum 80 mA trigger current reliably under all operating temperatures.

Triacs Part Context

This part belongs to the QxxxxLTx series of Quadrac devices developed by Littelfuse. These integrated triacs combine a diac trigger within the same package as the main triac, simplifying assembly and reducing component count compared to discrete solutions.

Triacs Replacement Considerations

Direct substitutes within the Q6025L6xx series may be available. Verify equivalent current ratings, voltage capabilities, and package isolation characteristics before substitution.
