Q6008VH4TP

Triacs Overview

The Q6008VH4TP is a bidirectional triac from Littelfuse, rated for 600 V repetitive peak off-state voltage and 8 A RMS on-state current. It utilizes a TO-251-3 (IPak) surface-mount package with short leads. The device features a maximum holding current of 35 mA and a gate trigger current of 35 mA. It supports a junction temperature range from -40 °C to +125 °C. The component exhibits a typical on-state voltage of 1.6 V and a non-repetitive peak surge current capability of 85 A.

Triacs Feature Summary

• Surface-mount construction in a compact TO-251-3 IPak package for automated assembly
• High thermal stability supporting operation up to 125 °C junction temperature
• Low gate sensitivity with defined trigger current and voltage thresholds
• Robust surge current handling capability for transient load protection

Triacs Applications

• Lighting control systems requiring surface-mount TRIACs
• Solid-state relay circuits for AC load switching
• Motor speed control applications in consumer appliances
• General-purpose AC power switching modules

Triacs Procurement Notes

Verify the specific suffix H4TP against official Littelfuse documentation to confirm pinout orientation and lead configuration. Ensure the selected variant matches the required thermal management strategy for the TO-251-3 package. Confirm RoHS compliance status through the manufacturer's latest release notes. Validate that the gate trigger characteristics align with the driving circuit design before finalizing procurement orders.

Triacs Selection Notes

Select this component when a surface-mount TRIAC is required for 600 V AC applications. The TO-251-3 package offers a smaller footprint compared to through-hole alternatives like TO-220. Consider the 8 A RMS rating and 85 A surge capacity for appropriate load matching. Evaluate thermal dissipation requirements given the limited heat sinking area inherent to the IPak form factor.

Triacs Part Context

This part belongs to the Q6008 series of high-reliability triacs designed for general-purpose AC switching. The series includes various packages such as TO-220AB and TO-252 variants. The Q6008VH4TP specifically addresses the need for compact surface-mount solutions while maintaining the electrical performance standards of the broader family.

Triacs Replacement Considerations

Q6008DH4TP provides similar electrical ratings in a TO-252-3 package. Q6008RH4TP offers the same specifications in a TO-220AB through-hole package. Verify pin compatibility and thermal resistance differences when substituting these alternatives.
