QV6016NH5TP

Overview

The QV6016NH5TP is a high-temperature Alternistor TRIAC from the QVxx16xHx series, manufactured by Littelfuse (formerly IXYS). It features a TO-263 (D²-PAK) surface-mount package with a maximum junction temperature of 150°C. The device supports an RMS on-state current of 16 A and offers a voltage capability of 600 V. It provides a surge handling capability of 200 A at 60 Hz for a single half-cycle. The component operates in quadrants I, II, and III, making it suitable for AC power control applications requiring high commutation capability.

Feature Summary

• High thermal robustness with a maximum junction temperature of 150°C
• Mechanically and thermally robust TO-263 clip-attach assembly
• High dv/dt capability up to 1000 V/µs
• Halogen-free and RoHS-compliant construction

Applications

• Heater control such as coffee brewers, tankless water heaters, and infrared heaters
• AC solid-state relays
• Light dimmers including incandescent and LED lighting
• Motor speed control in kitchen appliances, power tools, and home/white goods

Procurement Notes

Verify the manufacturer designation, as the datasheet indicates Littelfuse ownership while the model prefix suggests IXYS lineage. Confirm the specific gate trigger current sensitivity required for the design, as the 'H5' suffix denotes a 50 mA sensitivity level. Ensure the TO-263 package footprint matches the target PCB layout and that the soldering profile adheres to the specified reflow parameters to prevent thermal damage.

Selection Notes

Select this component for applications requiring surface-mount TRIACs with high surge tolerance and elevated temperature operation. The 600 V rating and 16 A current capacity are suitable for standard AC line voltages. Consider the 50 mA gate sensitivity for driver compatibility. Evaluate thermal management requirements based on the 45 °C/W junction-to-ambient thermal resistance for ambient cooling scenarios.

Part Context

This part belongs to the QVxx16xHx series of 16 A high-temperature Alternistor TRIACs. The series includes variants with different packages (TO-220AB, TO-220 isolated, TO-263) and gate sensitivities (10 mA, 20 mA, 35 mA, 50 mA). The QV6016NH5TP specifically utilizes the TO-263 surface-mount package and the highest gate sensitivity option within the standard lineup.

Replacement Considerations

Direct replacements within the same series include QV6016LH5TP (TO-220 Isolated) and QV6016RH5TP (TO-220 Non-Isolated), provided the package form factor change is acceptable. Other sensitivities like QV6016NH2TP or QV6016NH4TP may be used if gate drive conditions allow.
