LJ4008D8RP

Triacs Overview

The Littelfuse LJ4008D8RP is a sensitive gate triac designed for surface-mount applications. It features an RMS on-state current of 8 A and a rated repetitive off-state voltage of 800 V. The device operates within a junction temperature range of -40°C to +150°C. Key electrical parameters include a maximum on-state voltage of 1.5 V, a gate trigger voltage of 1.3 V, and a gate trigger current of 35 mA. The leakage current in the off-state is specified at 10 µA under VDRM conditions. It is housed in a TO-252-3 package.

Triacs Feature Summary

• Sensitive gate architecture ensuring reliable control in Quadrants I, II, III, and IV
• Glass-passivated junctions for enhanced parameter stability and long-term reliability
• Electrically isolated surface-mount package design

Triacs Applications

• AC power switching circuits requiring high voltage isolation
• Industrial motor control systems
• Solid-state relay implementations

Triacs Procurement Notes

Verify the specific suffix RP against official Littelfuse documentation to confirm reel packaging specifications. Ensure compatibility with standard SMD reflow profiles. Cross-reference the part number with authorized distributors to confirm current availability status and lead times prior to procurement planning.

Triacs Selection Notes

Select this component when an 8 A RMS current rating and 800 V blocking capability are required in a compact surface-mount form factor. The sensitive gate characteristic allows for direct interfacing with digital logic without complex drive circuitry. Verify thermal management requirements for the TO-252 package based on the expected load duty cycle.

Triacs Part Context

This device belongs to the Teccor line of sensitive gate triacs produced by Littelfuse. It shares functional similarities with other models in the series, such as the L4008D8, but offers specific voltage and current ratings tailored for higher power AC control applications. The product line emphasizes robustness in electrically noisy environments.

Triacs Replacement Considerations

The L4008D8 is a comparable alternative within the same manufacturer's portfolio. Verify pinout compatibility and ensure that the replacement part meets or exceeds the 800 V and 8 A requirements of the original design.
