L4006D6TP

Triacs Overview

The L4006D6TP is a low-power TRIAC manufactured by Littelfuse Inc., designed for AC switching and phase control applications. It features a maximum off-state voltage of 400V and a maximum load current of 6A. The device utilizes a sensing gate configuration with specific gate trigger current requirements of 5mA, 5mA, 5mA, and 10mA across different quadrants. It is housed in a surface-mount DPAK (TO-252) package, making it suitable for compact circuit designs requiring reliable bidirectional solid-state switching.

Triacs Feature Summary

• Sensing gate architecture for precise phase control
• Low power consumption design for efficient operation
• Surface-mount DPAK packaging for automated assembly

Triacs Applications

• Motor speed control systems
• Temperature modulation circuits
• AC phase control applications

Triacs Procurement Notes

Verify the exact ordering suffix to ensure the correct package variant and tape/reel specifications are selected. Confirm that the 400V rating aligns with the peak inverse voltage requirements of the target AC line or load. Ensure the 6A continuous current capacity meets the thermal dissipation capabilities of the printed circuit board layout. Cross-reference the sensing gate characteristics against the driving circuit's output capability to guarantee reliable triggering under all operating conditions.

Triacs Selection Notes

Select this component when a surface-mount TRIAC is required for low-voltage AC switching tasks. The 400V rating makes it appropriate for single-phase 120V or 230V applications where lower voltage margins are acceptable. Consider the DPAK package for space-constrained designs. Evaluate the gate sensitivity requirements against the microcontroller or driver interface to ensure sufficient drive current is available for consistent turn-on across all quadrants.

Triacs Part Context

This part belongs to the L4006 series of low-power TRIACs from Littelfuse. The series is engineered for general-purpose AC switching and phase control. The L4006D6TP specifically denotes the 400V voltage class and the DPAK surface-mount package option. It complements higher voltage variants within the same family, offering a cost-effective solution for applications not requiring 600V or 800V ratings.

Triacs Replacement Considerations

Direct replacements must match the 400V rating, 6A current capacity, and DPAK footprint. Verify that any substitute TRIAC maintains compatible gate trigger characteristics for the sensing gate configuration. Ensure the replacement device supports the same mounting style and thermal performance metrics to maintain circuit integrity without redesigning the PCB layout.
