Q6008L5TP

Triacs Overview

The Littelfuse Q6008L5TP is a bidirectional triac from the Teccor QxxxxLTx series, rated for 600V repetitive peak off-state voltage and 8A RMS on-state current. It features a gate trigger voltage range of 33V to 43V, enabling reliable control in high-impedance logic circuits. The device exhibits a maximum on-state voltage of 1.6V and a holding current of 50mA. Packaged in an electrically isolated TO-220-2 (TO-220AB) configuration, it offers 2500Vrms isolation between leads and the mounting surface. Key electrical parameters include a 10uA off-state leakage current at 25°C and surge current capability of 80A.

Triacs Feature Summary

• Integrated diac trigger mechanism within the package eliminates external discrete components
• Electrically isolated TO-220 package removes need for separate insulators
• Glass-passivated junctions ensure long-term parameter stability
• Sensitive gate design supports direct digital logic interface

Triacs Applications

• AC phase control for lighting dimmers
• Motor speed control systems
• Temperature modulation controls
• Solid-state switching relays

Triacs Procurement Notes

Verify the specific suffix 'L5' against official Littelfuse documentation to confirm exact gate sensitivity and triggering characteristics. Ensure the TO-220-2 package variant matches thermal requirements. Confirm RoHS compliance status through the manufacturer's latest datasheet revision before finalizing procurement specifications.

Triacs Selection Notes

Select this component when high noise immunity and simplified circuit topology are required. The integrated diac reduces assembly complexity compared to standard triacs. Verify that the 600V rating aligns with the peak line voltage and transient spikes present in the target AC application environment.

Triacs Part Context

This part belongs to the Teccor Quadrac family, which combines a triac and diac in one unit. The QxxxxLTx series is designed for applications requiring robust AC switching without external snubber networks or discrete triggers. It serves as a cost-effective alternative to multi-component assemblies.

Triacs Replacement Considerations

Direct substitutes may include other Triac-Diac combinations if discrete components are acceptable. Verify pinout compatibility and thermal resistance values. Check if alternative parts require external snubber networks, which increases board space and component count.

Triacs FAQ
