QK006R5TP

Triacs Overview

The Littelfuse QK006R5TP is a bidirectional triac rated for 1000V repetitive peak off-state voltage and 6A RMS on-state current. It features a gate trigger voltage of 2.5V with maximum gate currents of 50mA or 75mA, depending on the specific variant configuration. The device exhibits an on-state voltage of 1.6V and maintains an off-state leakage current of 50µA at VDRM. Operating within a temperature range of -40°C to +125°C, it utilizes a TO-220-2 package.

Triacs Feature Summary

• Provides bi-directional solid-state switching capability for AC circuits
• Designed for phase control applications including motor speed regulation
• Supports temperature modulation functions in power electronics

Triacs Applications

• AC switching systems
• Phase control circuits
• Motor speed control
• Temperature modulation devices

Triacs Procurement Notes

Verify the exact datasheet revision and specific gate trigger current classification (50mA vs 75mA) against the manufacturer's official documentation before integration. Confirm that the TO-220-2 through-hole package aligns with the target PCB layout requirements. Ensure thermal management strategies account for the specified operating temperature limits during high-current operation phases.

Triacs Selection Notes

Select this component when a 1000V blocking voltage and 6A continuous current capacity are required for AC load control. The TO-220-2 package facilitates efficient heat dissipation compared to smaller surface-mount alternatives. Consider the specific gate sensitivity requirements, as variations exist within the series regarding trigger current thresholds.

Triacs Part Context

This part belongs to the Qxx06xx series from Littelfuse, representing a line of low-power triacs designed for robust AC switching. The series emphasizes reliability in industrial and consumer applications requiring precise phase control. The QK006R5TP specifically addresses needs for higher voltage isolation while maintaining compact through-hole form factors.

Triacs Replacement Considerations

Compatible substitutes include the QK006N5TP, which shares identical electrical ratings but utilizes a different SMTO-263-2 surface mount package. Verify pinout compatibility and thermal resistance differences when transitioning between through-hole and surface mount variants.
