L6004R8

Triacs Overview

The Littelfuse L6004R8 is a low-power TRIAC designed for AC switching and phase control applications. It features a sensitive gate structure with logic-level triggering capabilities, supporting four-quadrant operation. The device offers a rated repetitive off-state voltage of 600 V and handles an on-state current of 4 A. Key electrical parameters include an on-state voltage of 1.6 V, holding current maximum of 15 mA, and off-state leakage current of 5 uA at VDRM. Operating temperature ranges from -40 C to +110 C. Packaged in a TO-220-2 non-isolated tab configuration, it utilizes a passivated glass junction for enhanced reliability.

Triacs Feature Summary

• Sensitive gate design enabling logic-level triggering for simplified interface requirements
• Four-quadrant logic level TRIAC functionality ensuring reliable switching across all gate polarities
• Passivated glass junction construction providing robust protection against environmental stressors

Triacs Applications

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

Triacs Procurement Notes

Verify the specific ordering suffix R8 corresponds to the required package and tape/reel or bulk configuration as defined by Littelfuse. Confirm that the TO-220-2 non-isolated tab variant meets thermal management requirements for the target PCB layout. Ensure compatibility with logic-level drive signals given the sensitive gate characteristics. Cross-reference datasheet specifications for derating curves under high ambient temperature conditions.

Triacs Selection Notes

Select this component when a 600 V blocking capability and 4 A continuous current rating are sufficient for the load. The sensitive gate feature makes it suitable for direct interfacing with microcontrollers or logic ICs without additional driver circuitry. Consider the TO-220-2 package for through-hole mounting where heat sinking via the tab is feasible. Evaluate the 1.6 V on-state voltage drop for power dissipation calculations in low-voltage AC systems.
