Q2006LT

Triacs Overview

The Littelfuse Q2006LT is a Quadrac device from the Teccor brand, integrating a triac and a diac trigger within a single package. This bidirectional AC switch operates with a gate control for either polarity of main terminal voltage. It features glass-passivated junctions for reliability and parameter stability. The device is housed in an electrically isolated TO-220 package, rated at 2500V rms isolation from leads to mounting surface. It supports on-state currents ranging from 4A to 15A and voltage ranges from 200V to 600V across the series.

Triacs Feature Summary

• Integrated diac trigger eliminates discrete component assembly
• Bidirectional AC switching with gate control for either voltage polarity
• Electrically isolated TO-220 package reduces insulation requirements
• Glass-passivated junctions ensure long-term device reliability

Triacs Applications

• AC speed controls
• Temperature modulation controls
• Lighting controls requiring noise immunity

Triacs Procurement Notes

Verify the specific part number suffix against official Littelfuse documentation to confirm exact electrical ratings and package variations. Ensure the selected variant meets the required isolation voltage and current specifications for the target application. Consult factory resources for custom design options if standard parameters are insufficient.

Triacs Selection Notes

Select this component for applications requiring integrated phase control without external snubber networks or discrete diacs. Consider the TO-220 package isolation rating when designing thermal management and mounting strategies. Verify that the specific model's voltage and current ratings align with the circuit's peak operating conditions.

Triacs Part Context

This component belongs to the QxxxxLTx series of Teccor Quadrac devices developed by Littelfuse. These devices combine a triac and diac to simplify AC switching designs. The series offers various current and voltage ratings to accommodate different power levels in industrial and consumer electronics.

Triacs Replacement Considerations

No public confirmed substitute part numbers are available in the provided data. Evaluate alternative Quadrac devices from other manufacturers only if they match the integrated triac-diac configuration and TO-220 isolation requirements.

Triacs FAQ

What is the primary advantage of using a Quadrac device over a discrete triac and diac?

The Quadrac device saves expense and assembly time by integrating the diac trigger inside the same package as the triac, eliminating the need for separate components.

Is external isolation required for the TO-220 package?

No external isolation is required because the TO-220 package is electrically isolated to 2500V rms from the leads to the mounting surface.

How does the device handle gate control?

It is a bidirectional AC switch that is gate controlled for either polarity of main terminal voltage.
