L2004L8

Triacs Overview

The Littelfuse L2004L8 is a sensitive-gate TRIAC designed for AC power switching and phase control applications. It features a maximum on-state RMS current of 4 A and an off-state voltage rating of 200 V. The device utilizes a TO-220-2 package with through-hole mounting, supporting a maximum operating temperature of +110 °C and a minimum of -40 °C. Its gate trigger voltage is specified at a maximum of 1.3 V, ensuring compatibility with low-power logic circuits.

Triacs Feature Summary

• Sensitive gate architecture enables reliable triggering from low-current logic interfaces
• Bi-directional solid-state switching capability for AC circuit control
• Robust thermal performance suitable for high-temperature industrial environments

Triacs Applications

• Light dimmer circuits
• Motor speed controls
• AC phase control systems

Triacs Procurement Notes

Verify the specific ordering suffix to confirm package style and tape/reel options if applicable. Ensure the procurement channel provides original manufacturer documentation to validate RoHS compliance status. Cross-reference the part number against the latest Littelfuse Teccor series catalog to confirm availability and any recent design changes or obsolescence notices before finalizing purchase orders.

Triacs Selection Notes

Select this component when a 200 V blocking voltage and 4 A continuous current capacity are required for AC loads. The sensitive gate characteristic makes it suitable for direct interface with microcontrollers or low-power optocouplers without additional drive amplification. Consider the TO-220-2 package for efficient heat dissipation in space-constrained designs requiring robust thermal management.

Triacs Part Context

This device belongs to the Littelfuse Teccor line of sensitive gate TRIACs, which offers current capabilities up to 8 A and various voltage ratings starting from 200 V. The series is engineered for general-purpose AC switching, providing a balance of sensitivity and power handling within a standard through-hole form factor widely used in consumer and industrial electronics.

Triacs Replacement Considerations

Consult official Littelfuse substitution guides for compatible TRIACs within the same voltage and current class. Verify that alternative parts maintain the sensitive gate requirement to ensure circuit compatibility without redesigning the drive stage.
