QJ6008DH3TP

Triacs Overview

The Littelfuse QJ6008DH3TP is an Alternistor triac designed for AC switching and phase control applications. It features a TO-252 (D-PAK) surface-mount package with three terminals. The device supports an RMS on-state current of 8 A and a rated repetitive off-state voltage of 800 V. Key electrical parameters include a maximum on-state voltage of 1.5 V, a gate trigger voltage of 1.3 V, and a gate trigger current of 10 mA. The component operates within a temperature range of -40°C to +150°C and exhibits a maximum off-state leakage current of 10 µA at the rated voltage.

Triacs Feature Summary

• High commutation capability characteristic of the Alternistor design
• Sensitive gate control suitable for digital circuitry in Quadrants I and IV
• Robust thermal performance supporting high-temperature operation up to 150°C

Triacs Applications

• Motor speed modulation controls
• Temperature modulation systems
• Lighting controls
• Static switching relays

Triacs Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm the packaging configuration, as standard part numbers may vary between tube, cut tape, or reel formats. Ensure the procurement channel provides traceability to the original manufacturer to guarantee component authenticity and compliance with RoHS standards.

Triacs Selection Notes

Select this component when an 800 V rating is required for AC phase control circuits. The sensitive gate specification facilitates direct interfacing with low-power digital logic controllers. Verify that the PCB layout accommodates the TO-252 footprint and provides adequate thermal dissipation for the 8 A continuous current requirement.

Triacs Part Context

This device belongs to the QJxx08xH series of high-temperature Alternistor triacs from Littelfuse. These components are engineered specifically for applications demanding high commutation rates and reliable switching under harsh electrical conditions, distinguishing them from standard sensitive gate triacs.

Triacs Replacement Considerations

Compatible substitutes within the same family include QJ6008DH4RP, which shares identical electrical ratings but differs in packaging format.
