Q8016LH6

Triacs Overview

The Littelfuse Q8016LH6 is a bidirectional triac designed for AC power control applications. It features an RMS on-state current of 16 A and a rated repetitive off-state voltage (VDRM) of 800 V. The device operates within a junction temperature range of -40°C to +125°C and utilizes a TO-220-2 through-hole package. Key electrical parameters include a maximum holding current of 70 mA, a gate trigger current of 80 mA, and a typical on-state voltage of 1.6 V. Non-repetitive peak on-state currents are specified at 167 A and 200 A under different pulse conditions.

Triacs Feature Summary

• High-voltage blocking capability suitable for mains-connected loads
• Robust thermal performance with high junction temperature rating
• Standardized pinout configuration for easy integration

Triacs Applications

• Solid-state relays
• AC motor speed controls
• Lighting dimmers

Triacs Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm exact gate sensitivity and packaging variations. Ensure the component meets RoHS compliance requirements for the target market. Cross-reference the datasheet revision date to validate parameter accuracy before finalizing procurement specifications.

Triacs Selection Notes

Select this component when an 800 V blocking voltage and 16 A continuous current capacity are required in a through-hole format. Compare gate trigger characteristics against the driving circuit capabilities to ensure reliable turn-on. Evaluate thermal management needs based on the expected load current and ambient operating conditions.

Triacs Part Context

This part belongs to the Qxx16xHx series of high-voltage triacs from Littelfuse. The series offers various gate sensitivities and voltage ratings while maintaining a consistent 16 A current handling capability. The Q8016LH6 specifically targets applications requiring robust switching performance in standard industrial enclosures.

Triacs Replacement Considerations

Direct replacements may include other 800 V, 16 A triacs in TO-220 packages from manufacturers such as STMicroelectronics or Vishay. Verify pin compatibility and gate trigger thresholds before substitution.
