Q2004L4

Triacs Overview

The Littelfuse Q2004L4 is a gated triac from the Teccor Electronics line of bidirectional semiconductors. It features an electrically isolated Compak surface-mount package with three leads, designed for compact circuit layouts. The device supports voltage capabilities up to 1000 V and surge currents up to 200 A. It incorporates glass-passivated junctions for reliability and is RoHS compliant. Packaged in embossed carrier tape with 2,500 devices per reel, it serves as a direct replacement for SOT-223 configurations in AC switching applications.

Triacs Feature Summary

• Electrically isolated Compak surface-mount package
• Glass-passivated junctions for long-term reliability
• RoHS compliant construction

Triacs Applications

• AC switching circuits
• Phase control systems
• Compact power electronics requiring surface-mount isolation

Triacs Procurement Notes

Verify the specific datasheet version and manufacturer origin (Littelfuse or New Jersey Semi-Conduct) when sourcing, as both entities list this part number. Confirm that the Compak package dimensions match the target PCB footprint, especially if replacing legacy SOT-223 designs. Ensure the supplier provides official RoHS compliance documentation consistent with the component's environmental specifications.

Triacs Selection Notes

Select the Q2004L4 when high voltage blocking capability (up to 1000 V) and electrical isolation are required in a small surface-mount form factor. The Compak package offers a lower profile than traditional through-hole options while maintaining robust surge handling. Consider this device for designs where space constraints preclude larger packages but isolation standards necessitate separation between gate and main terminals.

Triacs Part Context

This component belongs to the broad family of Teccor Electronics bidirectional semiconductors, which range from 0.8 A to 35 A and 200 V to 1000 V. It complements other surface-mount solutions like the PICO fuses and Quadrac devices by providing isolated triac functionality in a compact footprint suitable for modern dense PCB assemblies.

Triacs Replacement Considerations

The Q2004L4 can replace SOT-223 packaged triacs. Verify pinout compatibility and thermal dissipation requirements when substituting into existing designs originally using standard SOT-223 components.
