Q6008L4

Triacs Overview

The Littelfuse Q6008L4 is a standard triac designed for power control applications. It features an 8 A RMS on-state current and a 600 V repetitive off-state voltage rating. The device operates within a junction temperature range of -40°C to +125°C. Key electrical parameters include a maximum gate trigger current of 25 mA, a maximum holding current of 50 mA, and a maximum gate trigger voltage of 1.3 V. Non-repetitive peak on-state currents are rated at 83 A and 100 A. It is housed in a TO-220 package with an isolated tab.

Triacs Feature Summary

• Standard triac configuration for general-purpose AC switching
• High thermal stability across extended industrial temperature ranges
• Robust surge current handling capability for inductive loads

Triacs Applications

• AC motor speed control circuits
• Solid-state relay output stages
• Lighting dimmer controls

Triacs Procurement Notes

Verify the specific manufacturer part number against official Littelfuse documentation to confirm availability status. Note that distribution channels may indicate discontinuation or limited stock. Confirm RoHS compliance and packaging details directly with authorized suppliers before finalizing procurement plans.

Triacs Selection Notes

Select this component when a through-hole triac with 600V blocking capability and 8A continuous current is required. Ensure the application circuit provides sufficient gate drive current exceeding 25 mA. Verify that the PCB layout accommodates the TO-220 footprint and allows for adequate heatsinking given the thermal characteristics.

Triacs Part Context

This device belongs to the Q6008 series of high-reliability triacs from Littelfuse. The series is engineered for robust performance in demanding power electronics environments. The Q6008L4 specifically utilizes a leaded TO-220 package, distinguishing it from surface-mount variants like the Q6008NH4RP which use SMTO-263 packages.

Triacs Replacement Considerations

Direct replacements must match the 600V/8A specification and TO-220-3 isolated tab package. Cross-reference with other manufacturers' equivalent standard triacs ensuring identical pinout and thermal resistance ratings.
