L201E3AP

Triacs Overview

The L201E3AP is a Logic-Sensitive Gate TRIAC manufactured by Littelfuse Inc., designed for AC power control applications. It features an isolated TO-92 package and supports a maximum off-state voltage of 200 V with a maximum on-state current of 1 A RMS. The device requires a low gate trigger current, typically up to 5 mA, facilitating direct interface with logic circuits. It is lead-free and RoHS compliant, ensuring environmental safety standards are met for modern electronic assemblies.

Triacs Feature Summary

• Logic-sensitive gate architecture enables direct interfacing with standard digital logic outputs without requiring additional driver circuitry.
• Isolated TO-92 through-hole package provides compact mounting and reliable thermal dissipation for discrete semiconductor applications.

Triacs Applications

• Low-power AC switching in consumer electronics
• Solid-state relay input stages
• Lighting control circuits

Triacs Procurement Notes

Verify the specific manufacturer part number against official Littelfuse documentation to confirm the exact suffix designation and compliance status. Ensure that the procurement source provides valid traceability data and confirms the component meets current environmental regulations such as RoHS. Cross-reference the datasheet revision date to ensure compatibility with design specifications.

Triacs Selection Notes

Select this component when a low-current AC switch is required for logic-level control signals. The 200 V rating suits low-voltage AC lines, while the 1 A current capacity limits usage to small loads. Consider the TO-92 package constraints for PCB layout and thermal management requirements in enclosed designs.

Triacs Part Context

This component belongs to the Littelfuse discrete thyristor family, specifically within the TRIAC category. It is engineered for general-purpose power control tasks where size and logic compatibility are prioritized over high-power handling capabilities.

Triacs Replacement Considerations

Consult official Littelfuse substitution guides for verified equivalents. Generic replacements may differ in gate sensitivity or holding current characteristics, potentially affecting circuit reliability.

Triacs FAQ

What is the maximum gate trigger current for the L201E3AP?

The maximum gate trigger current is specified as 5 mA, allowing it to be driven directly by standard logic gates.

Does the L201E3AP support high-frequency operation?

The datasheet does not specify a maximum operating frequency; typical TRIACs operate at line frequencies (50/60 Hz). Verify switching speed requirements against the specific application load.
