QK016NH6TP

Triacs Overview

The Littelfuse QK016NH6TP is a bidirectional triac designed for high-power switching applications. It features a rated repetitive off-state voltage (VDRM) of 1 kV and an on-state RMS current (It RMS) of 16 A. The device operates within a temperature range of -40°C to +125°C and utilizes an SMTO-263-2 surface-mount package. Key electrical characteristics include a maximum holding current of 70 mA, a gate trigger current of 80 mA, and a gate trigger voltage of 2.5 V. Non-repetitive peak on-state currents are specified at 167 A and 200 A under different pulse conditions. The component exhibits a typical on-state voltage of 1.6 V and a maximum off-state leakage current of 100 uA.

Triacs Feature Summary

• High-voltage blocking capability suitable for demanding AC power control environments
• Robust surge handling with defined non-repetitive peak current ratings
• Surface-mount construction optimized for automated PCB assembly processes

Triacs Applications

• Industrial motor speed control systems

Triacs Procurement Notes

Verify the specific suffix configuration against the manufacturer datasheet to ensure compatibility with required thermal and electrical specifications. Confirm RoHS compliance status through official documentation prior to integration. Validate that the SMTO-263-2 footprint matches the target PCB design constraints and soldering profile requirements.

Triacs Selection Notes

Select this component when a 1 kV rating is necessary for the application voltage levels. Ensure the gate drive circuit can supply the specified 80 mA trigger current reliably. Consider the thermal management requirements associated with the 16 A RMS current rating in the chosen enclosure environment.

Triacs Part Context

This part belongs to the Qxx16xHx series of triacs from Littelfuse. The series provides standardized performance metrics for general-purpose AC switching. The specific model distinguishes itself through its 1 kV voltage rating and particular gate sensitivity parameters compared to lower voltage variants.

Triacs Replacement Considerations

QK016NH4TP offers similar current and voltage ratings but differs in gate trigger current and leakage specifications. Verify functional equivalence before substitution.
