QJ6006NH4RP

Triacs Overview

The Littelfuse QJ6006NH4RP is a bidirectional triac (Alternistor) designed for high-temperature AC switching applications. It features a 6 A RMS on-state current and a 600 V rated repetitive off-state voltage. The device operates within a junction temperature range of -40 °C to +125 °C. Key electrical parameters include a maximum holding current of 35 mA, a gate trigger voltage of 1.3 V, and a gate trigger current of 35 mA. The on-state voltage is specified at 1.6 V, with a non-repetitive peak on-state current capability of 85 A. It utilizes an SMTO-263-2 surface-mount package.

Triacs Feature Summary

• High-temperature operation capability up to 125 °C
• Integrated Alternistor design eliminates external snubber networks
• Glass-passivated junctions ensure long-term reliability

Triacs Applications

• AC motor speed controls
• Solid-state relays
• Lighting dimmers

Triacs Procurement Notes

Verify the specific ordering suffix against official Littelfuse documentation to confirm package type and tape-and-reel specifications. Ensure the selected variant matches the required thermal management and PCB footprint constraints for the target assembly process.

Triacs Selection Notes

Select this component when a surface-mount TRIAC with integrated snubber functionality is required for compact designs. Compare the 6 A current rating and 600 V blocking voltage against circuit requirements. Verify that the SMTO-263-2 package fits the available board space and thermal dissipation needs.

Triacs Part Context

This part belongs to the Littelfuse Qxx06xxH series of Alternistor TRIACs. These devices are engineered to replace traditional TRIAC-snubber combinations by integrating the necessary components internally. This integration reduces bill-of-materials count and simplifies layout for phase-control circuits.

Triacs Replacement Considerations

The Q6006NH4TP is a similar 6 A, 600 V Alternistor in a TO-263AB package. Verify pinout compatibility and thermal resistance differences before substitution. Other series members like Q6006L5TP offer through-hole options but differ in packaging and some electrical characteristics.
