Q8010L4TP

Triacs Overview

The Littelfuse Q8010L4TP is a bidirectional triac belonging to the Qxx10xx series, designed for surface-mount applications in the SMTO-263-2 package. It features an RMS on-state current of 10 A and a rated repetitive off-state voltage (VDRM) of 800 V. The device exhibits a maximum holding current of 35 mA and a gate trigger voltage of 2.5 V. Operating within a temperature range of -40°C to +125°C, it ensures reliable switching performance with a non-repetitive peak on-state current capability of 100 A or 120 A depending on specific test conditions.

Triacs Feature Summary

• Bidirectional conduction capability for AC power control applications
• Surface-mount construction utilizing the SMTO-263-2 package format
• High thermal stability supporting operation up to +125°C junction temperature

Triacs Applications

• AC motor speed control circuits
• Solid-state relay output stages
• Lighting dimmer modules

Triacs Procurement Notes

Verify the exact suffix against the manufacturer's official datasheet to confirm pinout orientation and specific electrical tolerances. Ensure the ordering code matches the required packaging configuration. Cross-reference the component marking with the latest Littelfuse documentation to prevent substitution errors during assembly.

Triacs Selection Notes

Select this component when an 800 V blocking voltage and 10 A continuous current rating are required in a compact surface-mount footprint. Evaluate the gate trigger characteristics against the driving circuit capabilities. Confirm that the thermal management design supports the specified operating temperature range under expected load conditions.

Triacs Part Context

This part belongs to the Qxx10xx family of high-power triacs from Littelfuse. The series is engineered for robust industrial and consumer power control needs. The Q8010L4TP variant specifically addresses applications requiring high voltage isolation and moderate current handling in space-constrained printed circuit board layouts.

Triacs Replacement Considerations

Consult the Littelfuse replacement guide for direct equivalents. Verify pin compatibility and thermal resistance values before substituting with other manufacturers' triacs in the same voltage and current class.
