QK016RH3

Triacs Overview

The QK016RH3 is a TRIAC Alternistor from Littelfuse Inc., designed for snubberless applications. It features a rated repetitive off-state voltage of 1 kV and an on-state RMS current of 16 A. The device supports non-repetitive on-state currents of 167 A and 200 A under specified conditions. Operating temperature ranges from -40°C to +125°C (TJ). It utilizes a TO-220-3 through-hole package with a non-isolated tab, suitable for high-power control circuits requiring robust switching capabilities.

Triacs Feature Summary

• Snubberless design eliminates the need for external RC networks
• High voltage blocking capability up to 1 kV
• Through-hole mounting for secure mechanical attachment

Triacs Applications

• Industrial motor control systems
• Resistive load switching applications
• Power regulation circuits

Triacs Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package type matches TO-220-3 requirements. Ensure storage conditions comply with moisture sensitivity levels if applicable. Cross-reference part numbers with Littelfuse documentation to avoid counterfeit substitutions during procurement processes.

Triacs Selection Notes

Select this component when snubberless operation is required to simplify circuit design. Consider the 16 A RMS current rating for load compatibility. Verify thermal management needs given the TO-220 package and 125°C junction temperature limit. Ensure gate trigger characteristics align with control logic voltage levels for reliable switching performance in target applications.
