Q6X8E4

Triacs Overview

The Littelfuse Q6X8E4 is a bidirectional triac rated for 600V repetitive off-state voltage and 0.8A RMS on-state current. It features a TO-92-3 through-hole package with a maximum junction temperature of 110°C. The device supports non-repetitive peak on-state currents of 8.3A and 10A, with an on-state voltage of 1.6V. Gate triggering parameters include a maximum holding current of 10mA and gate trigger voltages/currents ranging from 2V/5mA to 2V/10mA depending on the quadrant.

Triacs Feature Summary

• Designed as a low-power bi-directional solid state switch for AC switching applications
• Capable of phase control functions including motor speed regulation and temperature modulation
• Utilizes a standard TO-92-3 through-hole package for easy integration into circuit boards

Triacs Applications

• AC power switching circuits
• Motor speed control systems
• Temperature modulation controllers

Triacs Procurement Notes

Verify the specific datasheet version and electrical characteristics against the manufacturer's official documentation before finalizing design specifications. Confirm that the TO-92-3 package dimensions and thermal requirements align with the target application's physical constraints. Ensure compliance with RoHS standards if required by the end product regulations.

Triacs Selection Notes

Select this component when a compact, low-current triac is needed for general AC phase control or switching tasks. The 600V rating suits standard single-phase AC line voltages. Consider the 0.8A RMS limit for load capacity and verify gate drive compatibility with the 5mA to 10mA trigger current range to ensure reliable turn-on across all quadrants.

Triacs Part Context

The Q6X8E4 belongs to Littelfuse’s low-power TRIAC series, which offers ratings up to 1200V. This specific model provides a balance of moderate voltage blocking and sufficient current handling for small loads. It is part of a family designed for cost-effective solutions in consumer electronics and industrial control panels requiring simple AC switching capabilities.

Triacs Replacement Considerations

Consult Littelfuse official cross-reference guides for verified substitutes. Generic equivalents may differ in gate sensitivity or surge current ratings.
