L2004D5RP

Triacs Overview

The L2004D5RP is a sensitive gate TRIAC manufactured by Littelfuse Inc., designed for surface-mount applications. It features a TO-252-3 (DPAK) package and supports a repetitive peak off-state voltage of 200V with an on-state current rating of 4A. The device operates within a junction temperature range of -40°C to 110°C. Key electrical characteristics include a holding current of 10mA and a logic-compatible sensitive gate structure, facilitating direct integration with microcontroller outputs in power control circuits.

Triacs Feature Summary

• Sensitive gate architecture enabling direct drive from low-power logic circuits
• Surface-mount TO-252-3 packaging for automated assembly compatibility
• High thermal performance supporting operation up to 110°C junction temperature

Triacs Applications

• Solid-state relay modules requiring compact form factors
• Lighting control systems utilizing logic-level triggering
• Motor speed control circuits for small appliances

Triacs Procurement Notes

Verify component authenticity through authorized Littelfuse distributors due to obsolete status. Confirm lot date codes against project timelines as availability may be limited. Request datasheet revisions to ensure compliance with current design specifications. Validate package marking accuracy to distinguish from potential counterfeit units during incoming inspection processes.

Triacs Selection Notes

Select this component when surface-mount topology is required for 200V AC switching applications. Ensure the 4A current rating meets load requirements without derating constraints. Verify that the sensitive gate trigger characteristics align with the driving circuit's output voltage levels. Consider thermal management strategies given the DPAK package limitations compared to larger through-hole alternatives.

Triacs Part Context

This device belongs to the Teccor series of thyristors, specifically engineered for sensitive gate operations. It represents a transition point in Littelfuse's discrete semiconductor portfolio where surface-mount solutions were prioritized for consumer electronics manufacturing efficiency. The part number suffix indicates specific packaging and testing configurations defined by the manufacturer.

Triacs Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete product status, direct pin-to-pin replacements must be verified against updated Littelfuse application notes or engineering change notices. Cross-reference with newer generation SMD TRIACs only after validating electrical parameter compatibility.
