QK006L5

Triacs Overview

The Littelfuse QK006L5 is a bidirectional triac designed for high-voltage AC switching applications. It features a rated repetitive off-state voltage (VDRM) of 1 kV and an RMS on-state current (It RMS) of 6 A. 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 characteristics include a maximum holding current of 50 mA, a gate trigger voltage of 2.5 V, and an on-state voltage of 1.6 V. Non-repetitive peak currents are specified at 65 A and 80 A, with a maximum off-state leakage current of 50 uA under rated voltage conditions.

Triacs Feature Summary

• High voltage blocking capability suitable for industrial AC control
• Robust thermal performance across extended operating temperatures
• Standardized through-hole mounting for reliable PCB integration

Triacs Applications

• Industrial motor speed control systems
• Solid-state relay modules
• AC power regulation circuits

Triacs Procurement Notes

Verify component authenticity through authorized Littelfuse distributors or certified partners. Confirm RoHS compliance status via the official datasheet before procurement. Check for obsolescence notices as the product lifecycle status may affect long-term availability. Ensure packaging integrity matches specification requirements for storage and handling.

Triacs Selection Notes

Select this component when a 1 kV rating is required for AC load switching. Compare gate trigger sensitivity against driving circuit capabilities. Evaluate thermal management needs based on the 6 A RMS current rating and TO-220-2 package thermal resistance. Verify that the 50 mA holding current meets minimum load requirements to prevent unintended turn-off.

Triacs Part Context

The QK006L5 belongs to the Qxx06xx series of triacs from Littelfuse. This series focuses on general-purpose high-voltage thyristor solutions. The component shares core electrical specifications with other variants in the family but differs in package type and specific thermal characteristics. It serves as a standard solution for medium-power AC control tasks.

Triacs Replacement Considerations

Direct pin-compatible substitutes within the same series should be verified against the official replacement guide. Cross-reference VDRM and It RMS ratings to ensure equivalent performance. Validate gate trigger parameters for compatibility with existing drive circuits.
