QJ8008N5RP

Triacs Overview

The Littelfuse QJ8008N5RP is a high-temperature standard triac designed for surface-mount applications. It features an RMS on-state current of 8 A and a rated repetitive peak off-state voltage of 800 V. The device operates within a junction temperature range of -40 °C to +150 °C. Key electrical parameters include a maximum holding current of 50 mA, a gate trigger voltage of 1.3 V, and a gate trigger current of 50 mA. It utilizes a TO-263AB-3 (D²Pak) package with a maximum on-state voltage of 1.6 V.

Triacs Feature Summary

• High-temperature operation capability up to 150 °C
• Surface-mount D²Pak package design
• Standard gate trigger characteristics

Triacs Applications

• Industrial motor control systems
• Solid-state relay modules
• Lighting dimmer circuits

Triacs Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Littelfuse or authorized distributors before procurement. Confirm that the TO-263AB-3 package dimensions match the target PCB footprint requirements. Ensure thermal management strategies account for the 150 °C maximum junction temperature limit during operation.

Triacs Selection Notes

Select this component when a robust 800 V blocking voltage and 8 A continuous current are required in a compact surface-mount form factor. The 150 °C rating makes it suitable for environments with elevated ambient temperatures. Compare against the Q8008N5RP if lower temperature ratings are acceptable, or consider higher current variants like the QJ8010N5RP for increased load capacity.

Triacs Part Context

This part belongs to the Littelfuse Teccor QJ series of high-temperature triacs. The series is engineered for reliability in demanding power control applications. The 'QJ' prefix typically denotes specific high-temperature and ruggedized characteristics compared to standard series offerings from the manufacturer.

Triacs Replacement Considerations

Direct pin-compatible replacements within the same series include the QJ8010N5RP for higher current handling. Verify that any substitute maintains the 800 V voltage rating and compatible gate trigger specifications to ensure circuit functionality without redesign.
