Q6008DH3RP

Triacs Overview

The Q6008DH3RP is an 8 A high-temperature Alternistor triac from the Littelfuse QJxx08xHx series, designed for AC switching and phase control. It features a peak repetitive off-state voltage (VDRM) of 800 V and operates within a junction temperature range of -40 °C to +150 °C. Key electrical parameters include an on-state voltage of 1.5 V, a gate trigger voltage (VGT) of 1.3 V, and a gate trigger current (IGT) of 10 mA. The device exhibits a low off-state leakage current of 10 µA. Packaged in a surface-mount TO-252-3 (D-PAK) case, it is supplied in cut tape or reel formats.

Triacs Feature Summary

• Alternistor design eliminates the need for external snubber networks in circuits with extremely inductive loads.
• Sensitive gate type ensures reliable control in Quadrants I and IV, facilitating compatibility with digital control circuitry.
• High commutation capability supports operation in Quadrants I, II, and III for demanding AC switching applications.

Triacs Applications

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

Triacs Procurement Notes

Verify the specific suffix 'RP' against the manufacturer's official documentation to confirm packaging details such as cut tape versus reel quantities. Ensure the component meets RoHS compliance requirements for the intended assembly process. Cross-reference the TO-252-3 package dimensions with PCB layout specifications to guarantee mechanical fit and thermal performance during integration.

Triacs Selection Notes

Select this component when high-temperature stability and sensitive gate triggering are required for digital interface compatibility. The 800 V rating suits medium-voltage AC applications, while the Alternistor architecture simplifies design by removing snubber components. Verify that the 10 mA gate trigger current aligns with the driving circuit's output capabilities for reliable turn-on across the specified operating temperature range.

Triacs Part Context

This part belongs to the QJxx08xHx series of 8 Amp high-temperature triacs manufactured by Littelfuse under the Teccor brand. The series includes variants with different voltage ratings and package options, specifically designed for robust AC power control. The 'H' designation typically indicates the Alternistor feature set, distinguishing it from standard or sensitive-only triacs within the broader product family.

Triacs Replacement Considerations

Consult Littelfuse official substitution guides for verified equivalents. Potential alternatives may include other 8 A, 800 V Alternistor triacs in TO-252 packages from the same manufacturer, provided gate trigger characteristics and thermal ratings match the original design constraints.
