QK010N4RP

Triacs Overview

The Littelfuse QK010N4RP is a bidirectional triac designed for surface-mount applications, belonging to the Qxx10xx series. It features an SMTO-263-2 package and supports SMD/SMT installation styles. The device handles a continuous RMS on-state current of 10 A with a rated repetitive off-state voltage (VDRM) of 1 kV. Key electrical parameters include a maximum holding current of 35 mA, a gate trigger voltage of 2.5 V, and a gate trigger current ranging from 25 mA to 50 mA. It operates within a temperature range of -40°C to +125°C, exhibits a typical on-state voltage of 1.6 V, and maintains a leakage current of 10 µA at VDRM.

Triacs Feature Summary

• High-voltage blocking capability suitable for demanding AC power control environments
• Surface-mount construction optimized for automated PCB assembly processes
• Robust thermal performance supporting operation up to 125°C junction temperature

Triacs Applications

• Industrial motor speed control systems
• Solid-state relay designs requiring high voltage isolation
• AC power switching circuits in consumer appliances

Triacs Procurement Notes

Verify component authenticity through authorized Littelfuse distributors or certified supply chain partners. Confirm RoHS compliance status via official datasheets before integration. Ensure storage conditions maintain moisture sensitivity levels appropriate for lead-free surface-mount devices during handling and reflow soldering processes.

Triacs Selection Notes

Select this component when 1 kV blocking voltage and 10 A RMS current capacity are required in a compact surface-mount form factor. Compare against Q8010N4RP for lower voltage needs or QK008NH4RP for different gate sensitivity profiles. Validate thermal management requirements against the SMTO-263-2 package limitations for specific PCB layouts.

Triacs Part Context

This part belongs to the Qxx10xx series of high-power triacs from Littelfuse, engineered for robust AC switching. It shares the 10 A RMS current rating with variants like Q8010N4RP but distinguishes itself through its 1 kV voltage rating. The series emphasizes reliability in industrial and commercial power control applications where space constraints necessitate surface-mount solutions.

Triacs Replacement Considerations

QK010N4TP serves as a tube-packaged alternative within the same series. Verify pinout compatibility and thermal characteristics when substituting between reel and tube packaging formats for equivalent circuit performance.
