Q4006DH3RP

Triacs Overview

The Q4006DH3RP is a bidirectional triac from Littelfuse, rated for 400 V repetitive peak off-state voltage and 6 A RMS on-state current. It features a non-repetitive surge current capacity of 55 A or 65 A depending on pulse duration, with an on-state voltage of 1.6 V. The device operates within a temperature range of -40°C to +125°C and utilizes an SMTO-263-2 surface-mount package. Gate triggering parameters include a maximum holding current of 15 mA, a gate trigger voltage of 1.3 V, and a gate trigger current of 10 mA.

Triacs Feature Summary

• Integrated thermal protection design for enhanced reliability in high-power switching applications
• Glass-passivated junctions ensure long-term parameter stability and device durability
• Surface-mount construction facilitates automated assembly and compact PCB layout

Triacs Applications

• AC motor speed control systems
• Solid-state relay implementations
• Lighting dimmer circuits

Triacs Procurement Notes

Verify the specific suffix RP against official Littelfuse documentation to confirm packaging configuration and tape-and-reel specifications. Ensure compatibility with existing board layouts regarding the SMTO-263-2 footprint and thermal pad requirements. Cross-reference datasheet revisions to confirm static electrical parameters remain unchanged for production integrity.

Triacs Selection Notes

Select this component when a 400 V blocking capability and 6 A continuous current rating are required in a surface-mount form factor. Compare gate sensitivity requirements against the 1.3 V trigger voltage specification. Evaluate thermal management needs based on the 1.6 V on-state voltage drop and available PCB copper area for heat dissipation.

Triacs Part Context

This part belongs to the Qxx06xxH series of bidirectional triacs designed for general-purpose AC power control. The series offers various voltage ratings while maintaining consistent current handling capabilities. The Q4006DH3RP specifically targets applications requiring robust switching performance in a compact SMD package.

Triacs Replacement Considerations

Direct substitutes may include other 400V 6A triacs in SMTO-263 packages from Littelfuse or competitors, provided gate characteristics and thermal resistance values match the original design constraints.
