QJ6008DH4TP

Triacs Overview

The QJ6008DH4TP is a bidirectional triac from Littelfuse, designed for surface-mount applications in the TO-252-3 (D-Pak) package. It features an RMS on-state current of 8 A and a rated repetitive off-state voltage of 600 V. The device operates within a temperature range of -40°C to +150°C. Key electrical parameters include a maximum holding current of 35 mA, a gate trigger voltage of 1.3 V, and a gate trigger current of 35 mA. On-state voltage is specified at 1.5 V, with a leakage current of 10 µA at VDRM.

Triacs Feature Summary

• Integrated thermal protection mechanism for enhanced reliability under overload conditions
• Glass-passivated junctions ensure long-term parameter stability and device longevity
• Surface-mount D-Pak packaging facilitates automated assembly and compact circuit design

Triacs Applications

• AC motor speed control circuits
• Solid-state relay switching applications
• Lighting dimmer and phase control systems

Triacs Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm package type and tape/reel specifications. Ensure compatibility with RoHS and REACH requirements for the target market. Confirm that the TO-252-3 footprint matches the PCB layout constraints before finalizing procurement orders.

Triacs Selection Notes

Select this component when an 8 A RMS current rating and 600 V blocking voltage are required in a surface-mount form factor. Consider the 150°C maximum junction temperature for high-thermal environments. Verify gate sensitivity requirements align with the 35 mA trigger current specification for the driving circuit interface.

Triacs Part Context

This part belongs to the QJxx08xH series of thermally protected triacs by Littelfuse. The series is engineered for robust AC power switching, combining high current handling with integrated thermal shutdown capabilities to prevent catastrophic failure during short-circuit or overcurrent events.

Triacs Replacement Considerations

The Q6008DH4RP is a related variant within the same manufacturer portfolio, offering similar electrical characteristics but potentially differing in packaging configuration or thermal protection specifics. Cross-reference datasheets to verify pinout and thermal performance equivalence.
