LX807MTRP

Triacs Overview

The Littelfuse LX807MTRP is a bidirectional triac from the LX8 series, designed for AC switching and phase control applications. It features a sensitive gate configuration suitable for digital logic control in Quadrants I and IV. The device has an RMS on-state current of 0.8 A and a repetitive peak off-state voltage rating of 600 V. Key electrical parameters include a maximum holding current of 5 mA and a maximum gate trigger current of 5 mA. It operates within a junction temperature range of -40°C to 110°C and is housed in a TO-92 (TO-226AA) package.

Triacs Feature Summary

• Sensitive gate design enabling reliable triggering with low gate drive currents for direct interface with digital logic circuits.
• Bidirectional AC switching capability optimized for phase control applications such as motor speed regulation and lighting dimming.
• Glass-passivated junction construction ensuring long-term parameter stability and protection against environmental factors.

Triacs Applications

• AC motor speed control systems
• Lighting dimmer circuits
• Temperature modulation controls

Triacs Procurement Notes

Verify the specific suffix 'MTRP' indicates the tape and reel packaging format when ordering. Confirm that the 600V voltage rating aligns with the circuit requirements, as other variants in the LX807 family may offer different voltage levels. Ensure the TO-92 through-hole package fits the designated PCB footprint and verify compliance with relevant RoHS directives for the manufacturing batch.

Triacs Selection Notes

Select this component when a compact triac with a 600V blocking voltage and 0.8A continuous current capacity is required. The sensitive gate characteristic makes it appropriate for microcontroller-driven applications where minimal gate current is available. Consider thermal management constraints given the small TO-92 package size and the 110°C maximum junction temperature limit during high-duty cycle operations.

Triacs Part Context

This part belongs to the Littelfuse LX8 series of Triacs, which includes various voltage and current ratings. The LX807 variant specifically denotes the 600V rating within this lineup. The MTRP suffix typically signifies the reel packaging method used for automated surface mount or through-hole assembly processes, distinguishing it from bulk or cut-tape versions.

Triacs Replacement Considerations

Compatible substitutes include the LX803MERP, which shares the same 0.8A current rating but offers a higher 600V rating with potentially different gate sensitivity characteristics. Other LX807 variants with different voltage ratings (e.g., 400V) are electrically distinct and require careful evaluation before substitution.
