L401E6

Triacs Overview

The L401E6 is a logic-sensitive gate TRIAC manufactured by Littelfuse Inc., designed for through-hole mounting in TO-92 packages. It features a maximum off-state voltage rating of 400 V and an on-state current capacity of 1 A. The device operates within a temperature range from -65°C to +110°C. Key electrical parameters include a gate trigger voltage (Vgt) of 2 V and gate trigger currents (Igt) specified at 5 mA and 10 mA. This component is RoHS3 compliant and suitable for applications requiring precise gate control with low power input.

Triacs Feature Summary

• Logic-sensitive gate architecture for efficient triggering
• Through-hole TO-92 package construction
• Wide operating temperature range capability

Triacs Applications

• Lighting control systems
• Motor speed regulation circuits
• Heating element control

Triacs Procurement Notes

Verify the specific gate trigger current variant required, as specifications list both 5 mA and 10 mA options. Confirm RoHS3 compliance status matches project requirements. Ensure the TO-92 through-hole mounting style aligns with PCB design constraints. Cross-reference the 400 V voltage rating against circuit peak voltages to prevent overvoltage failure during operation.

Triacs Selection Notes

Select this component when low gate drive power is essential for triac activation. The 400 V rating suits lower voltage AC mains applications. Consider the TO-92 package size for space-constrained designs. Evaluate the -65°C minimum temperature limit for harsh environment suitability. Compare gate trigger thresholds against available driver output capabilities to ensure reliable switching performance.

Triacs Part Context

This part belongs to the family of logic-sensitive gate TRIACs produced by Littelfuse. These devices are engineered to respond to standard logic-level signals, reducing the need for complex gate drive circuits compared to conventional TRIACs. The TO-92 form factor provides a compact solution for moderate current applications in consumer electronics and industrial controls.

Triacs Replacement Considerations

Equivalent parts include other 400 V, 1 A logic-sensitive TRIACs in TO-92 packages. Verify pinout compatibility before substitution. Check that alternative components meet the same gate trigger voltage and current specifications to maintain circuit functionality.
