QK016NH3RP

Triacs Overview

The Littelfuse QK016NH3RP is a bidirectional triac designed for surface-mount applications. It features an RMS on-state current of 16 A and a rated repetitive off-state voltage (VDRM) of 800 V. The device exhibits a maximum on-state voltage of 1.6 V and a gate trigger current (Igt) of 80 mA. Non-repetitive peak on-state currents are specified at 167 A and 200 A. Leakage current in the off-state is limited to 5 uA under VDRM conditions. The component operates within a temperature range of -40 C to +125 C and is housed in an SMTO-263-2 package.

Triacs Feature Summary

• High-voltage blocking capability suitable for demanding power control environments
• Surface-mount construction facilitates automated assembly processes
• Robust thermal performance across extended industrial temperature ranges

Triacs Applications

• Solid-state relay implementations
• Industrial motor speed control circuits
• Lighting dimmer systems

Triacs Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm exact electrical tolerances and packaging configurations. Ensure compatibility with existing board layouts and thermal management requirements before finalizing procurement decisions.

Triacs Selection Notes

Compare the 800 V rating against system voltage peaks to ensure adequate safety margins. Evaluate gate drive capabilities against the 80 mA trigger requirement. Consider the SMTO-263-2 footprint for PCB space constraints and verify thermal dissipation needs for continuous 16 A operation.

Triacs Part Context

This component belongs to the Qxx16xHx series of high-power triacs from Littelfuse. The series shares common physical dimensions and basic switching characteristics, differentiated primarily by voltage ratings and specific gate sensitivity parameters defined by their unique model suffixes.

Triacs Replacement Considerations

Direct substitutes include the Q8016NH3RP and QK016NH4RP. Verify pinout compatibility and ensure replacement devices meet or exceed the original 800 V blocking voltage and 16 A current handling specifications.
