Q8008R5

Triacs Overview

The Littelfuse Q8008R5 is a single-phase Triac rated for 800V repetitive peak off-state voltage and an RMS on-state current of 8A. It operates within a junction temperature range of -40°C to +125°C. The device features a maximum gate trigger voltage of 1.3V and a maximum gate trigger current of 50mA. It utilizes a TO-220AB flange mount package with three terminals, where the case connects to Main Terminal 2. Key electrical characteristics include a holding current of 50mA and a critical rate of rise of off-state voltage of 100 V/µs.

Triacs Feature Summary

• High reliability construction designed for robust industrial environments
• Flange mount configuration facilitates efficient thermal dissipation via the main terminal
• Sensitive gate drive capability allows for direct interfacing with logic-level control circuits

Triacs Applications

• Industrial motor speed control systems
• Solid state relay implementations
• General purpose AC power switching applications

Triacs Procurement Notes

Verify the specific suffix designation against manufacturer documentation to confirm pinout orientation and thermal pad connectivity. Ensure the procurement channel provides original manufacturer certification to guarantee component authenticity and traceability for quality assurance purposes.

Triacs Selection Notes

Select this component when an 8A RMS current rating at 800V blocking voltage is required in a through-hole flange mount package. Consider the 50mA gate trigger requirement for driver circuit compatibility. Evaluate thermal management needs based on the TO-220AB package's heat dissipation capabilities relative to the application's duty cycle.

Triacs Part Context

This part belongs to the Littelfuse Teccor series of high-power thyristors. It shares the 8A/800V performance class with variants such as the Q8008L5TP and Q8008N5RP, differing primarily in packaging style and specific electrical tolerances defined by the manufacturer's product line structure.

Triacs Replacement Considerations

Cross-reference with Q8008L5TP or Q8008N5RP for equivalent electrical ratings. Verify that alternative packages accommodate the same thermal and mechanical mounting constraints before substitution.
