QJ6008L5TP

Triacs Overview

The Littelfuse QJ6008L5TP is a high-temperature sensitive gate TRIAC rated for 8 A RMS on-state current and 600 V repetitive peak off-state voltage. It operates within a junction temperature range of -40 °C to +150 °C and features a maximum on-state voltage of 1.4 V at rated current. The device utilizes a TO-220AB-3 insulated package designed for through-hole mounting, ensuring electrical isolation from the heatsink. Key electrical characteristics include a holding current maximum of 50 mA, a gate trigger voltage of 1.3 V, and a gate trigger current of 50 mA. Leakage current in the off-state is limited to 10 µA under rated voltage conditions.

Triacs Feature Summary

• Sensitive gate architecture enabling reliable triggering with low gate drive power requirements.
• High thermal stability supporting continuous operation at elevated junction temperatures up to 150 °C.
• Integrated insulation in the TO-220AB-3 package providing electrical isolation between the terminal and mounting hardware.

Triacs Applications

• Solid-state relays requiring high-temperature resilience
• Industrial motor control circuits
• Lighting dimmer applications

Triacs Procurement Notes

Verify the specific suffix 'TP' against the manufacturer datasheet to confirm the exact packaging configuration and material compliance status. Ensure the procurement documentation explicitly references the Littelfuse part number QJ6008L5TP to distinguish it from non-insulated or different current-rated variants within the same series. Cross-reference the RoHS declaration with the latest official product change notification to ensure regulatory alignment.

Triacs Selection Notes

Select this component when an 8 A RMS current rating and 600 V blocking capability are required for AC load switching. The sensitive gate characteristic simplifies driver circuit design by reducing the necessary gate trigger current. Verify that the application environment supports the specified operating temperature range and that the thermal management strategy accommodates the power dissipation associated with the 1.4 V on-state voltage drop at full load.

Triacs Part Context

This device belongs to the Qxx06xH series of high-temperature TRIACs manufactured by Littelfuse. The series encompasses various current ratings and voltage classes, all sharing common high-temperature operational capabilities and sensitive gate technology. The QJ6008L5TP specifically represents the 8 A variant within this family, distinguished by its insulated TO-220AB-3 package suitable for direct heatsink mounting without additional insulators.

Triacs Replacement Considerations

Direct replacements must match the 8 A RMS current, 600 V voltage rating, and sensitive gate specifications. Verify pinout compatibility and package dimensions for the TO-220AB-3 form factor. Consider alternatives only if they offer equivalent thermal performance and confirmed electrical parameter parity as documented in official substitution lists.
