Q6008L559

Triacs Overview

The Littelfuse Q6008L559 is a standard TRIAC rated for 600V repetitive peak off-state voltage and 8A RMS on-state current. It utilizes an isolated tab TO-220 package designed for through-hole mounting. The device supports a junction temperature range from -40°C to +125°C, with a maximum holding current of 35mA and gate trigger current of 35mA. It features a typical on-state voltage of 1.6V and low leakage current of 10µA at rated voltage.

Triacs Feature Summary

• Isolated tab construction for direct heatsink mounting without electrical isolation components
• High surge capability supporting non-repetitive on-state currents up to 100A
• Robust dv/dt rating ensuring reliable commutation in high-frequency switching environments

Triacs Applications

• Industrial motor control systems
• Solid-state relay modules
• General-purpose AC power switching circuits

Triacs Procurement Notes

Verify the specific suffix L559 against the manufacturer datasheet to confirm pinout compatibility and thermal resistance specifications. Ensure the procurement channel provides original Littelfuse documentation to validate RoHS compliance status and manufacturing origin before finalizing component selection.

Triacs Selection Notes

Select this component when high-voltage isolation is required between the heatsink and circuit ground. The TO-220 form factor suits applications needing robust mechanical stability and efficient heat dissipation. Confirm that the 8A RMS rating aligns with the continuous load requirements of the target application design.

Triacs Part Context

This part belongs to the general purpose TRIAC family within Littelfuse's thyristor portfolio. It serves as a cost-effective solution for medium-power AC control tasks. The standardized TO-220 package ensures broad availability across various electronic assembly platforms and industrial equipment designs.

Triacs Replacement Considerations

Direct substitutes include the Q6008RH4 and QJ6008RH4TP, which share identical electrical ratings but differ in packaging or temperature capabilities.
