L401E5AP

Triacs Overview

The L401E5AP is a bidirectional triac from Littelfuse, rated for 400V and 1A. It features a sensing gate structure with a sensitivity range of 5-5-5-5mA. The component is designed for AC power control applications and is housed in a surface-mount package.

Triacs Feature Summary

• Bidirectional triac configuration for AC switching
• Sensing gate architecture for low drive current requirements
• Surface-mount packaging for automated assembly

Triacs Applications

• AC motor speed control
• Lighting dimmer circuits
• Solid-state relay outputs

Triacs Procurement Notes

Verify the specific suffix 'AP' against the official Littelfuse datasheet to confirm package type and tape-and-reel specifications. Ensure the 400V rating aligns with the target circuit voltage. Confirm lead times directly with authorized distributors as manufacturing schedules vary.

Triacs Selection Notes

Select this component when a low-current gate trigger is required for 400V AC loads. Compare the 1A RMS current rating against peak load demands. Verify that the surface-mount footprint matches the PCB design constraints and thermal management requirements.

Triacs Part Context

This part belongs to Littelfuse's triac family, which includes various voltage and current ratings. The L401 series typically offers robust performance for general-purpose AC control. The E5 suffix often denotes specific packaging or reliability standards within the product line.

Triacs Replacement Considerations

Check for direct replacements with identical 400V/1A ratings and sensing gate characteristics. Verify pinout compatibility before substitution. Consider higher voltage ratings if derating is required for safety margins.
