QK006DH3RP

Triacs Overview

The QK006DH3RP is a bidirectional triac manufactured by Littelfuse, designed for surface-mount applications in the TO-252 (D-Pak) package. It belongs to the QKxx06xH series and features an RMS on-state current of 6 A with a rated repetitive off-state voltage of 1000 V. The device exhibits a maximum on-state voltage of 1.4 V and a gate trigger voltage of 1.3 V. Operating within a temperature range from -40 °C to +150 °C, it ensures reliable switching performance. The component is supplied in reel packaging and complies with RoHS standards.

Triacs Feature Summary

• High voltage blocking capability suitable for demanding AC power control environments
• Sensitive gate design allowing direct interfacing with low-power logic circuits
• Robust thermal management through metal-tab mounting in a surface-mount package

Triacs Applications

• Solid-state relays requiring high isolation and compact form factors
• AC motor speed control systems for industrial appliances
• Lighting dimmer circuits for residential and commercial fixtures

Triacs Procurement Notes

Verify the complete part number including the RP suffix to confirm reel packaging configuration. Ensure compatibility with lead-free reflow soldering profiles specified in the official datasheet. Confirm that the 1000 V rating aligns with the specific circuit requirements before integration into the final assembly design.

Triacs Selection Notes

Select this component when a 1000 V blocking voltage is required in a surface-mount topology. Compare against the QJ4006DH3RP if a lower 400 V rating suffices for the application. Consider the TO-252 package thermal resistance for heat dissipation needs in enclosed spaces.

Triacs Part Context

This triac is part of Littelfuse's Alternistor family, which integrates multiple semiconductor functions into a single package for improved reliability. The QK series specifically targets high-voltage AC switching applications where space constraints necessitate surface-mount technology over traditional through-hole solutions.

Triacs Replacement Considerations

The QJ4006DH3RP serves as a lower voltage alternative within the same package family. Verify pinout compatibility and thermal characteristics when substituting other 6 A TO-252 triacs from different manufacturers.
