Q4010LTTP

Triacs Overview

The Littelfuse Q4010LTTP is a Quadrac device, which integrates a triac and a diac trigger within a single package. It operates as a bidirectional AC switch with gate control for either polarity of main terminal voltage. The component features a TO-220 package that provides electrical isolation of 2500V rms from the leads to the mounting surface. Key parameters include an on-state current (Itrms) of 10A, a blocking voltage range (VBO) of 400V, and a maximum repetitive peak off-state voltage (VDRM) of 400V. It utilizes glass-passivated junctions for reliability.

Triacs Feature Summary

• Integrated diac trigger eliminates the need for discrete components and assembly time.
• Electrically isolated TO-220 package removes the requirement for external insulators.
• Glass-passivated junctions ensure long-term parameter stability.

Triacs Applications

• AC switching and phase control applications
• Speed controls
• Temperature modulation controls
• Lighting controls requiring noise immunity

Triacs Procurement Notes

Verify the specific suffix 'TP' against official Littelfuse documentation to confirm tape-and-reel packaging versus tube configuration. Confirm RoHS compliance status and REACH SVHC details through the manufacturer's datasheet or certification documents before procurement.

Triacs Selection Notes

Select this component for applications requiring integrated gate triggering without external diacs. Ensure the circuit design accommodates the 2500V rms isolation capability of the TO-220 package. Verify that the 10A RMS current rating and 400V blocking voltage meet the system's operational requirements.

Triacs Part Context

This part belongs to the QxxxxLTx series of Teccor brand Quadrac devices developed by Littelfuse. These devices are designed to simplify AC switching circuits by combining a triac and diac. The series offers current capacities ranging from 4A to 15A and voltage ranges from 200V to 600V.

Triacs Replacement Considerations

Check for other parts in the QxxxxLTx series with matching VDRM and Itrms ratings. Verify pinout compatibility if substituting with non-integrated triac/diac combinations.
