Q8010RH5TP

Triacs Overview

The Littelfuse Q8010RH5TP is a high-reliability bidirectional triac designed for robust power control applications. It features an RMS on-state current of 10 A and supports a rated repetitive off-state voltage (VDRM) of 800 V. The device operates within a temperature range of -40°C to +125°C and utilizes a TO-220AB package with three pins. Key electrical characteristics include a maximum holding current of 50 mA, a gate trigger voltage of 1.5 V, and a gate trigger current of 50 mA. It exhibits a minimum commutation critical rate of rise of dv/dt at 30 V/µs and a blocking state critical rate of rise of dv/dt at 650 V/µs.

Triacs Feature Summary

• High reliability construction suitable for demanding industrial environments
• Robust thermal management via TO-220AB through-hole packaging
• Enhanced switching performance with specified dv/dt ratings

Triacs Applications

• Industrial motor speed control systems
• Solid-state relay modules
• High-voltage AC power switching circuits

Triacs Procurement Notes

Verify the specific suffix 'H5' against official Littelfuse documentation to confirm high-reliability screening requirements. Ensure the TO-220AB pinout matches the target PCB footprint. Confirm RoHS compliance status directly from the manufacturer's latest datasheet before finalizing procurement specifications.

Triacs Selection Notes

Select this component when an 800 V rating is required for AC load control. The 10 A RMS current capacity suits moderate-power industrial loads. Verify that the 50 mA gate drive capability aligns with the available control circuitry output. Consider the TO-220AB package for adequate heat dissipation without additional active cooling.

Triacs Part Context

This part belongs to the Qxx10xx series of thyristors manufactured by Littelfuse. The series focuses on providing reliable triac solutions for general-purpose and specialized power control needs. The Q8010RH5TP specifically denotes a variant optimized for higher reliability standards compared to standard commercial grade devices.

Triacs Replacement Considerations

Consult Littelfuse official substitution guides for verified equivalents. Generic triacs may lack the specific high-reliability screening or exact dv/dt ratings required for mission-critical applications.
