L2004D5TP

Triacs Overview

The Littelfuse L2004D5TP is a bidirectional triac belonging to the Teccor Lxx04xx series, designed for AC power control applications. It features a 4A RMS on-state current rating and supports a repetitive peak off-state voltage of 400V. The device utilizes a 5mA gate trigger current for reliable switching and exhibits a low on-state voltage of 1.6V to minimize conduction losses. Packaged in a TO-220-2 (Tab) through-hole housing, it offers robust thermal management capabilities suitable for industrial and commercial power regulation systems requiring compact thyristor solutions.

Triacs Feature Summary

• Bidirectional AC power switching capability for precise load control
• Low on-state voltage drop for enhanced energy efficiency
• Robust TO-220-2 package design facilitating effective heat dissipation

Triacs Applications

• Industrial motor speed control circuits
• Commercial lighting dimming systems
• Solid-state relay output stages

Triacs Procurement Notes

Verify the specific suffix 'TP' against the manufacturer's latest datasheet to confirm tape-and-reel packaging specifications and lead-free compliance status. Ensure the ordering quantity aligns with the manufacturer's standard tube or reel configurations. Cross-reference the part number with authorized distributors to confirm current availability and authenticity before finalizing procurement orders.

Triacs Selection Notes

Select this component when an application requires a 4A bidirectional switch with a 400V blocking voltage. The 5mA gate sensitivity makes it suitable for low-power drive circuits. Verify that the TO-220-2 package dimensions fit the PCB layout and that the thermal resistance characteristics meet the system's heat dissipation requirements under maximum load conditions.

Triacs Part Context

This part belongs to the Littelfuse Teccor Lxx04xx series of silicon controlled rectifiers. This family provides general-purpose AC power control solutions characterized by high reliability and standardized pinouts. The series supports various voltage and current ratings within a consistent package form factor, simplifying design upgrades and replacements across different power levels.

Triacs Replacement Considerations

Direct substitutes include other 4A, 400V bidirectional triacs in TO-220 packages from manufacturers such as STMicroelectronics or Vishay. Verify equivalent gate trigger currents and on-state voltages to ensure circuit compatibility without redesigning the drive logic.
