QJ6006LH4TP

Triacs Overview

The Littelfuse QJ6006LH4TP is a high-temperature Alternistor TRIAC designed for robust power control applications. It features a 6 A RMS on-state current and a 600 V rated repetitive off-state voltage. The device operates within a junction temperature range of -40°C to +150°C, ensuring reliability in demanding environments. Key electrical parameters include a maximum holding current of 35 mA and a gate trigger voltage of 1.3 V. It utilizes a TO-220AB-3 through-hole package with an isolated tab for efficient thermal management and secure mounting.

Triacs Feature Summary

• High-temperature capability supporting operation up to +150°C junction temperature
• Alternistor technology providing rugged performance without snubber requirements
• Isolated tab design in TO-220AB-3 package for effective heat dissipation

Triacs Applications

• Industrial motor speed control systems
• Solid-state relay (SSR) output stages
• High-temperature lighting dimmer circuits

Triacs Procurement Notes

Verify the specific suffix 'H4TP' against the manufacturer's latest datasheet to confirm packaging and material compliance details. Ensure the procurement channel provides authentic Littelfuse components with traceable documentation. Cross-reference the part number with official distributor catalogs to validate current production status and RoHS compliance before finalizing orders.

Triacs Selection Notes

Select this component when applications require high surge current handling and operation at elevated temperatures exceeding standard TRIAC limits. The 6 A rating suits moderate power loads, while the 600 V blocking voltage fits general industrial AC line applications. Consider the TO-220AB-3 package constraints for PCB layout and heatsinking requirements compared to surface-mount alternatives.

Triacs Part Context

This part belongs to the Qxx06xH series of Alternistor TRIACs from Littelfuse. These devices are engineered for high-reliability power switching where thermal stability is critical. The series distinguishes itself through enhanced ruggedness and simplified drive requirements compared to conventional TRIACs, making it suitable for harsh industrial environments.

Triacs Replacement Considerations

Direct replacements must match the 6 A / 600 V specification and TO-220AB-3 isolated package. Verify that substitute parts maintain comparable non-repetitive peak on-state current ratings and gate trigger characteristics to ensure circuit compatibility without redesign.
