QJ6008VH2TP

Triacs Overview

The QJ6008VH2TP is a Littelfuse Alternistor TRIAC with a 600 V off-state voltage and 8 A RMS on-state current. It features a maximum holding current of 1.5 V and an off-state leakage current of 10 uA at rated voltage. The device operates up to +150°C junction temperature and supports surge currents up to 100 A at 60 Hz. Packaged in TO-251AA-3 for through-hole mounting, it is UL 1557 recognized as electrically isolated.

Triacs Feature Summary

• Snubberless Alternistor design for simplified circuit implementation
• Electrically isolated construction recognized under UL 1557
• High thermal stability with +150°C maximum operating temperature

Triacs Applications

• Half-bridge configurations requiring dual channel drive
• Industrial AC power control systems
• Solid-state relay applications

Triacs Procurement Notes

Verify the specific Littelfuse datasheet for the QJ6008VH2TP to confirm RoHS compliance status and detailed electrical characteristics. Ensure the TO-251AA-3 package dimensions match the target PCB footprint. Cross-reference the 600 V rating against peak line voltages to prevent overvoltage failure during procurement validation.

Triacs Selection Notes

Select this component when snubberless operation is required for 600 V AC loads. The 8 A RMS rating suits moderate power applications. Verify that the 100 A surge capability meets transient load requirements. The electrically isolated feature is critical for safety barriers in industrial environments where galvanic isolation is mandated by regulatory standards.

Triacs Part Context

This part belongs to Littelfuse's low-power TRIAC series offering voltage capabilities up to 1200 V. The QJ6008VH2TP specifically addresses the 600 V segment within the Alternistor family. It provides a balance of high surge handling and compact TO-251AA-3 packaging for space-constrained designs.

Triacs Replacement Considerations

Consult official Littelfuse substitution guides for compatible Alternistor TRIACs. Verify pinout compatibility and thermal resistance values before swapping. No direct public substitute part numbers are confirmed in the provided documentation.
