Q2015L6

Triacs Overview

The Littelfuse Q2015L6 is a Quadrac device, which integrates a triac and a diac trigger within a single package. This bidirectional AC switch is gate-controlled for either polarity of main terminal voltage. It is designed for AC switching and phase control applications such as speed controls, temperature modulation controls, and lighting controls where noise immunity is required. The device features glass-passivated junctions to ensure long-term reliability and parameter stability.

Triacs Feature Summary

• Integrates a triac and diac trigger in one package to save assembly time and cost
• Bidirectional AC switching capability with gate control for either main terminal voltage polarity
• Glass-passivated junctions for enhanced long-term device reliability and parameter stability

Triacs Applications

• Speed controls
• Temperature modulation controls
• Lighting controls requiring noise immunity

Triacs Part Context

The Q2015L6 belongs to the QxxxxLTx series of Teccor brand Quadrac devices developed by Littelfuse. These devices eliminate the need for discrete diacs and separate assembly steps. The series offers triac current capacities ranging from 4A to 15A with voltage ranges from 200V to 600V, typically available in TO-220 packages.

Triacs Replacement Considerations

Verify that any substitute component maintains the integrated Triac-Diac functionality and matches the required voltage and current ratings for the specific AC switching application.
