LX803MEAP

Triacs Overview

The Littelfuse LX803MEAP is a sensitive gate Triac belonging to the LX8 series, designed for AC power control applications. It features an RMS on-state current of 800 mA and supports non-repetitive peak on-state currents up to 8 A. The device offers a rated repetitive peak off-state voltage of 600 V with a maximum leakage current of 5 uA under VDRM conditions. Key electrical parameters include an on-state voltage of 1.6 V, a holding current maximum of 5 mA, and a gate trigger voltage of 1.3 V. Gate trigger current specifications range from 3 mA to 5 mA. The component operates within a temperature range of -40°C to +110°C and utilizes a TO-92 through-hole package.

Triacs Feature Summary

• Sensitive gate architecture enabling reliable triggering with low gate drive requirements
• Robust thermal performance supporting operation in high-temperature environments up to 110°C
• High voltage blocking capability suitable for standard AC line voltage applications

Triacs Applications

• Lighting control systems including dimmers and soft starters
• Small motor speed control circuits
• Solid state relays and switching modules
• General purpose AC load switching

Triacs Procurement Notes

Verify the specific ordering suffix MEAP to confirm the Ammo Pack packaging configuration, as Littelfuse offers multiple packaging options such as Cut Tape or Reel for this part number. Ensure the selected variant matches the required handling and automation equipment specifications for your assembly process. Cross-reference the manufacturer datasheet to confirm RoHS compliance status and REACH SVHC declarations prior to final procurement approval.

Triacs Selection Notes

Select the LX803MEAP when a 600 V rating is required instead of lower voltage variants like the LX803DE which is rated at 400 V. The 800 mA RMS current capacity makes it suitable for light loads but insufficient for higher power motor drives requiring 1 A or more. Verify that the sensitive gate characteristic aligns with the noise immunity requirements of the circuit design compared to standard gate devices.

Triacs Part Context

This component is part of the Littelfuse LX8 series of Triacs, which are optimized for general-purpose AC switching. The LX8 family provides a balance of cost-effectiveness and performance for consumer electronics and industrial controls. The LX803MEAP specifically denotes the 600 V version packaged in Ammo Packs, distinguishing it from other voltage ratings or packaging styles within the same electrical specification group.

Triacs Replacement Considerations

Direct substitutes include the LX803MERP (Reel packaging) and LX803DE (400 V rating, Bulk packaging). When replacing, ensure the alternative maintains the 600 V off-state voltage requirement if used in mains-connected circuits. Verify that the gate trigger current characteristics of the substitute match the driving circuit capabilities.
