L401E575

Triacs Overview

The Littelfuse L401E575 is a sensitive gate triac rated for 400V repetitive peak off-state voltage and 1A RMS on-state current. It features a TO-92 through-hole package with a holding current maximum of 10mA and a gate trigger current of 5mA. The device operates within a temperature range of -65°C to +110°C, offering a non-repetitive surge current capacity of up to 20A and an on-state voltage drop of 1.6V.

Triacs Feature Summary

• Sensitive gate architecture enabling reliable triggering with low gate current requirements
• Robust thermal performance supporting operation in extreme ambient temperatures
• Compact through-hole packaging suitable for space-constrained circuit board layouts

Triacs Applications

• Lighting control systems requiring precise phase angle regulation
• Solid-state relay circuits for AC load switching
• Motor speed control applications for small AC motors

Triacs Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure the correct variant is procured. Confirm that the component meets all relevant regulatory standards required for your target market. Cross-reference the datasheet parameters with your design specifications to validate compatibility with your circuit requirements before finalizing orders.

Triacs Selection Notes

Select this component when a low-power triac with sensitive gate characteristics is required for AC power control. Ensure the application voltage does not exceed the 400V rating and that the load current remains within the 1A RMS limit. Consider the TO-92 package constraints for thermal management and PCB layout space availability during the design phase.

Triacs Part Context

This part belongs to the TECCOR family of sensitive gate triacs manufactured by Littelfuse. These devices are designed for general-purpose AC power control applications where low drive power is essential. The series offers various voltage and current ratings to suit different industrial and consumer electronics needs.

Triacs Replacement Considerations

Consult official Littelfuse cross-reference guides for verified substitute part numbers. Do not assume functional equivalence based solely on similar electrical ratings without verifying pinout and package dimensions.
