L2N3

Triacs Overview

The Littelfuse L2N3 is a logic-level sensitive gate TRIAC designed for AC power switching and phase control applications. It features an off-state voltage rating of 200V and supports an RMS on-state current of 1A. The component is housed in a surface-mount DO-214AA SMB package, ensuring compact integration into circuit boards. It operates within a junction temperature range of -40°C to 125°C. The device is RoHS3 compliant and lead-free, suitable for modern electronic manufacturing standards requiring high reliability in low-power triac applications.

Triacs Feature Summary

• Logic-level sensitive gate design for direct interface with digital logic circuits
• Surface-mount construction in a compact DO-214AA SMB package
• Capable of handling AC power switching and phase control tasks

Triacs Applications

• Light dimmer circuits
• Small motor speed controls
• Thermostat heating element regulation

Triacs Procurement Notes

Verify the specific ordering suffix against the official Littelfuse datasheet to ensure the correct package variant and tape-and-reel configuration are selected. Confirm RoHS3 compliance status matches project requirements. Cross-reference the manufacturer part number with authorized distributor catalogs to avoid counterfeit components. Ensure storage conditions adhere to moisture sensitivity levels defined in the datasheet prior to assembly.

Triacs Selection Notes

Select this component when a low-gate-current trigger is required for logic-level interfacing. The 200V rating limits suitability to low-voltage AC systems only. Consider the 1A current limit for load capacity constraints. The surface-mount package necessitates PCB layout adjustments compared to through-hole alternatives. Evaluate thermal management requirements given the specified junction temperature range.

Triacs Part Context

This component belongs to the Littelfuse Sensitive Triacs series, which covers devices ranging from 0.8A to 8A. These parts are engineered for automotive and general industrial electronics where reliable AC switching is necessary. The L2N3 specifically addresses the lower end of the current spectrum, offering a balance between sensitivity and power handling in a small footprint.

Triacs Replacement Considerations

Consult the Littelfuse 398 Series documentation or equivalent manufacturer cross-reference guides for verified substitutes. Identify components with matching logic-sensitive gate characteristics and compatible DO-214AA packaging. Verify that alternative parts meet the same 200V blocking voltage and 1A current specifications.
