L6006L656

Triacs Overview

The Littelfuse L6006L656 is a TECCOR brand Triac designed for AC switching and phase control applications. It features an RMS on-state current of 6 A and a rated repetitive off-state voltage (VDRM) of 600 V. The device operates within a junction temperature range of -40 °C to +125 °C and utilizes a TO-220AB package with an isolated tab. Key electrical parameters include a maximum on-state voltage of 1.4 V, a holding current of 50 mA, and a gate trigger voltage of 1.3 V. It offers high surge capability with non-repetitive peak on-state currents up to 100 A or 120 A depending on the waveform.

Triacs Feature Summary

• Integrated glass-passivated junctions for enhanced reliability and parameter stability under thermal stress.
• Electrically isolated mounting tab in the TO-220AB package eliminates the need for external insulators.
• Sensitive gate design allows triggering with low microampere currents from sense coils or proximity switches.

Triacs Applications

• Phase control circuits for heating elements and temperature modulation systems.
• Motor speed controls for power tools and industrial equipment.
• Capacitive discharge ignition systems for gas engines and lighting strobes.

Triacs Procurement Notes

Verify the specific suffix configuration against the manufacturer's latest datasheet to ensure compatibility with required isolation ratings and thermal characteristics. Confirm RoHS compliance status and agency approvals such as UL recognition before finalizing component selection for regulated markets.

Triacs Selection Notes

Select this component for applications requiring robust AC switching with moderate current handling capabilities. Ensure the circuit design accounts for the specified gate trigger current limits and provides adequate heat sinking for the TO-220AB package to maintain junction temperatures within the operational range during continuous conduction.

Triacs Part Context

This part belongs to the Littelfuse TECCOR Qxx06xH series of standard TRIACs. It is engineered for general-purpose AC control tasks where reliable switching and noise immunity are critical. The series emphasizes durability through glass passivation and simplified installation via isolated packaging options.

Triacs Replacement Considerations

Direct substitutes may include other 6A 600V TRIACs in TO-220AB packages from manufacturers like STMicroelectronics or Vishay, provided gate sensitivity and thermal resistance specifications match the original design requirements.
