Q8006DH4RP

Triacs Overview

The Littelfuse Q8006DH4RP is a bidirectional triac (alternistor) from the Qxx06xxH series, rated for 800V repetitive peak off-state voltage and 6A RMS on-state current. It features an 85A non-repetitive peak on-state current capability and a maximum holding current of 35mA. The device exhibits a typical on-state voltage of 1.6V, with gate trigger parameters specified at 1.3V and 35mA. Designed for robust AC switching, it operates within standard industrial temperature ranges and utilizes surface-mount packaging to facilitate automated assembly in power control circuits.

Triacs Feature Summary

• Bidirectional alternistor architecture eliminates the need for external snubber networks
• Integrated glass-passivated junctions ensure long-term parameter stability
• Surface-mount package design supports high-volume automated PCB assembly

Triacs Applications

• AC phase control applications requiring noise immunity
• Solid-state relay (SSR) output stages
• Lighting dimmer circuits and temperature modulation controls

Triacs Procurement Notes

Verify the specific suffix 'RP' against the official Littelfuse datasheet to confirm exact tape-and-reel specifications and moisture sensitivity level. Ensure the ordering part number matches the required package variant and terminal finish before procurement to avoid compatibility issues with existing board layouts.

Triacs Selection Notes

Select this component when a bidirectional switch with integrated diac-like triggering characteristics is required without discrete snubber components. Verify that the 6A RMS current rating and 800V blocking voltage exceed the circuit's peak operational demands. Confirm that the surface-mount form factor aligns with the target PCB footprint and thermal management strategy.

Triacs Part Context

This device belongs to the Qxx06xxH series of alternistors, which combine triac functionality with internal triggering mechanisms. These devices are engineered to simplify AC switching designs by reducing component count and assembly time compared to traditional triac-diac combinations.

Triacs Replacement Considerations

Direct replacements must match the 800V/6A rating and surface-mount package dimensions. Verify pinout compatibility and thermal resistance values to ensure equivalent performance in the host application.
