QK010R5TP

Triacs Overview

The Littelfuse QK010R5TP is a bidirectional triac belonging to the Qxx10xx series, designed for high-voltage AC switching applications. It features a rated repetitive off-state voltage (VDRM) of 1 kV and an on-state RMS current (It RMS) of 10 A. The device operates within a temperature range of -40°C to +125°C and utilizes a TO-220-2 through-hole package. Key electrical parameters include a maximum holding current of 50 mA, a gate trigger voltage of 2.5 V, and an on-state voltage of 1.6 V. Non-repetitive peak on-state currents are specified at 100 A and 120 A, with a leakage current of 10 uA under VDRM conditions.

Triacs Feature Summary

• High voltage blocking capability suitable for industrial AC control
• Logic-level gate sensitivity for simplified driver interface
• Robust thermal performance across extended operating temperatures

Triacs Applications

• Industrial motor speed control systems
• Solid-state relay modules
• AC power regulation circuits

Triacs Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number against official Littelfuse documentation. Confirm that the physical marking on the TO-220-2 package matches the specified model identifier. Ensure compliance with RoHS and REACH standards as indicated in the technical datasheet prior to integration into final assemblies.

Triacs Selection Notes

Select this component when a 1 kV rating is required for AC load switching. Compare the 10 A RMS current capacity against circuit load requirements. Consider the TO-220-2 package for through-hole mounting constraints. Evaluate the 50 mA gate trigger current against available drive signal strength to ensure reliable turn-on characteristics.

Triacs Part Context

This triac is part of the Qxx10xx family, which standardizes 10 A current ratings across various voltage classes. Related variants include the Q4010R5TP (400 V), Q8010R5TP (800 V), and QK010N5TP (1 kV SMD). The suffix 'R' typically denotes specific gate sensitivity or packaging variations within the series.

Triacs Replacement Considerations

Direct substitutes within the same voltage and current class include QK010L5 and QK010N5TP. Verify pinout compatibility and thermal resistance values before substitution. Alternative packages such as SMTO-263 require PCB redesign.
