L4N5RP

Triacs Overview

The Littelfuse L4N5RP is a logic-level sensitive gate TRIAC housed in the DO-214AB (SMB) surface-mount package. It features a rated repetitive off-state voltage of 400 V and an on-state RMS current of 1 A. The device operates within a junction temperature range of -40°C to 125°C. Key electrical characteristics include a gate trigger current of 5 mA and a gate trigger voltage of 2 V, ensuring compatibility with standard logic circuits.

Triacs Feature Summary

• Logic-level sensitive gate design for direct interface with digital control signals
• Surface-mount construction in a compact DO-214AB package for automated assembly
• High thermal stability supporting operation up to 125°C junction temperature

Triacs Applications

• AC solid-state switching applications
• Low power heating controls
• Water valve actuation systems
• Solenoid driver circuits

Triacs Procurement Notes

Verify the specific suffix 'RP' against the manufacturer's official datasheet to confirm the exact tape-and-reel packaging configuration and marking codes. Ensure that the required operating voltage and current ratings align with the system design specifications before finalizing the procurement order.

Triacs Selection Notes

Select this component when a surface-mount TRIAC with low gate drive requirements is necessary. The 400 V rating suits lower voltage AC loads, while the 1 A current capacity limits its use to small-scale control applications. Verify that the DO-214AB footprint matches the PCB layout constraints.

Triacs Part Context

This part belongs to the LxNx series of low-power TRIACs from Littelfuse. These devices are engineered for general-purpose AC switching tasks where space efficiency and reliable logic interfacing are prioritized over high current handling capabilities.

Triacs Replacement Considerations

Consult the manufacturer's substitution guide for verified equivalents. Cross-reference pinout compatibility and electrical parameters such as VDRM and IT(RMS) to ensure functional interchangeability without redesigning the host circuit.
