L2004L3TP

Triacs Overview

The Littelfuse L2004L3TP is a bidirectional triac designed for AC power control applications. It features a 4 A RMS on-state current rating and supports a repetitive peak reverse voltage of 400 V. The device is housed in a TO-220 package with three pins for through-hole mounting. Key electrical characteristics include a maximum gate trigger current of 10 mA, a maximum gate trigger voltage of 1.3 V, and a peak on-state voltage of 1.6 V. It withstands a surge current of 55 A and maintains a holding current of 20 mA. The component operates within a temperature range of -40°C to 125°C.

Triacs Feature Summary

• Provides reliable AC switching capability with high surge current tolerance for robust circuit protection.
• Utilizes a standard TO-220 through-hole package to facilitate straightforward integration into industrial and consumer power boards.
• Ensures stable conduction states with defined gate trigger thresholds for predictable control logic.

Triacs Applications

• General purpose AC motor speed control circuits
• Solid state relay output stages
• Lighting dimmer implementations

Triacs Procurement Notes

Verify the specific suffix 'L3TP' against the manufacturer's official datasheet to confirm pinout orientation and thermal pad configuration. Ensure the selected variant matches the required 400 V blocking voltage and 4 A continuous current ratings for the target application environment. Cross-reference the package dimensions with the PCB footprint to guarantee mechanical compatibility during assembly.

Triacs Selection Notes

Select this component when a 400 V rated triac is required for moderate power AC loads. The TO-220 package allows for direct heatsinking if thermal management exceeds natural convection limits. Verify that the gate drive circuit can supply at least 10 mA to ensure reliable triggering across the specified temperature range without exceeding the peak gate power dissipation limit.

Triacs Part Context

This part belongs to Littelfuse's general-purpose triac family, which provides standardized solutions for AC power regulation. The L-series designation typically indicates specific gate sensitivity and voltage ratings within the broader portfolio. These components are widely used in household appliances and industrial controllers where cost-effective solid-state switching is necessary.

Triacs Replacement Considerations

Direct replacements must match the 4 A current, 400 V voltage, and TO-220 package constraints. Verify equivalent gate trigger specifications to maintain circuit stability. Consult manufacturer cross-reference lists for confirmed compatible parts with identical electrical performance profiles.
