L2004F51TP

Triacs Overview

The L2004F51TP is a sensitive-gate TRIAC from Littelfuse, designed for AC power switching. It features a 200 V blocking voltage and supports a maximum RMS on-state current of 4 A. The device utilizes a TO-202 through-hole package and operates within a junction temperature range of -40°C to 110°C. Its logic-sensitive gate design minimizes trigger current requirements, facilitating reliable control in low-power drive circuits.

Triacs Feature Summary

• Sensitive gate architecture reduces required trigger current for efficient control
• Four-quadrant logic operation ensures consistent performance across all voltage polarities
• Robust thermal handling capability suitable for demanding industrial environments

Triacs Applications

• AC power switching circuits
• Lighting control systems
• Motor speed regulation

Triacs Procurement Notes

Verify the specific ordering suffix to confirm the exact package variant and compliance status. Ensure the component matches the required voltage and current ratings for the target application. Confirm RoHS compliance and lead-free status with the supplier prior to purchase to meet regulatory standards.

Triacs Selection Notes

Select this component for applications requiring low gate drive current and high reliability. The 4 A rating suits moderate power loads. Consider the TO-202 package for through-hole mounting constraints. Evaluate thermal management needs given the 110°C maximum junction temperature limit.

Triacs Part Context

This part belongs to the Littelfuse Sensitive Triac family, covering currents from 0.8 A to 8 A. These devices are engineered for general-purpose AC control, offering improved sensitivity compared to standard gate TRIACs while maintaining robust electrical characteristics for industrial use.

Triacs Replacement Considerations

Consult official Littelfuse substitution guides for compatible alternatives. Verify that any replacement maintains the 200 V rating, 4 A current capacity, and sensitive gate specifications to ensure circuit compatibility.
