Q6008LTH

Triacs Overview

The Littelfuse Q6008LTH is a Quadrac device, which integrates a triac and an internal diac trigger within a single package. This bidirectional AC switch is designed for phase control applications requiring noise immunity. It features a TO-220AB (TO-220, 3 PIN) package with the case connected to Main Terminal 2. The device supports a rated repetitive off-state voltage of 600 V and an RMS on-state current of 8 A. Key electrical parameters include a maximum DC gate trigger current of 35 mA, a maximum DC gate trigger voltage of 1.5 V, and a maximum holding current of 35 mA. The component operates within a temperature range of -40 °C to +125 °C.

Triacs Feature Summary

• Integrates a diac trigger inside the same package as the triac to eliminate external components.
• Electrically isolated package construction for enhanced safety.
• High surge capability supporting up to 200 A non-repetitive peak current.
• Designed for AC switching and phase control where noise immunity is required.

Triacs Applications

• Speed controls for motors
• Temperature modulation controls
• Lighting controls

Triacs Procurement Notes

Verify the specific suffix 'H' against the manufacturer's datasheet to confirm it denotes the alternistor variant which eliminates the need for a snubber network. Ensure the ordering information matches the exact pinout and thermal characteristics defined in the official Littelfuse documentation for this series.

Triacs Selection Notes

Select this component when designing circuits that require integrated triggering without discrete diacs. The high voltage rating of 600 V and 8 A current capacity suit general AC power control tasks. Confirm compatibility with the TO-220AB footprint and verify thermal management requirements for the intended operating environment.

Triacs Part Context

This part belongs to the Teccor Quadrac family developed by Littelfuse. These devices combine a triac and a diac trigger in one unit to save assembly time and cost. The Q6008LTH specifically represents the 600V, 8A variant within this series, offering high reliability for industrial and consumer AC control applications.
