L4006L5TP

Triacs Overview

The Littelfuse L4006L5TP is a Teccor brand bidirectional triac designed for AC power control applications. It features a 600V repetitive peak off-state voltage (VDRM) and supports an average on-state current (ITAV) of 4A. The device utilizes a sensitive gate structure with a gate trigger current range of 5mA to 5mA, ensuring reliable switching in low-power drive circuits. Packaged in a TO-220-2 insulated tab configuration, it offers robust thermal management capabilities. Key electrical parameters include a holding current of 15mA and a non-repetitive peak surge current capability of 35A. The component operates within a junction temperature range of -40°C to +125°C, making it suitable for industrial and consumer AC motor speed controls and lighting dimmers.

Triacs Feature Summary

• Sensitive gate triggering for compatibility with logic-level control signals
• High thermal stability with insulated tab package for efficient heat dissipation
• Robust surge current handling for protection against transient load conditions

Triacs Applications

• AC motor speed control systems
• Lighting dimmer circuits
• Solid-state relay inputs

Triacs Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Littelfuse or authorized distributors before integration. Confirm that the TO-220-2 package insulation class meets your isolation requirements. Ensure gate sensitivity specifications align with your driving circuit's output capabilities to guarantee reliable turn-on under all operating temperatures.

Triacs Selection Notes

Select this component when a 600V blocking voltage and 4A continuous current rating are required for AC phase control. The sensitive gate variant is optimal for designs using low-current microcontrollers or optocouplers. Compare the TO-220-2 thermal resistance against your heatsinking strategy to ensure junction temperatures remain within the specified 125°C limit during continuous operation.

Triacs Part Context

The L4006L5TP belongs to the Teccor Lxx04xx series of bidirectional triacs manufactured by Littelfuse. This series is widely used in general-purpose AC power switching applications. The 'L5TP' suffix typically denotes the specific pinout, gate sensitivity, and TO-220-2 insulated tab packaging format standard for this product line.

Triacs Replacement Considerations

Potential substitutes include other 600V 4A sensitive gate triacs in TO-220 packages from manufacturers like STMicroelectronics or Vishay. Verify equivalent VDRM, ITAV, IGT, and package dimensions before substitution to maintain circuit performance and mechanical fit.
