QJ6016NH5RP

Overview

The QJ6016NH5RP is a 16 Amp Alternistor TRIAC from the QJxx16xHx series, designed for AC power control applications. It features a 600 V repetitive peak off-state voltage (VRRM) and operates in quadrants I, II, and III. The device utilizes a TO-263 (D²-PAK) surface-mount package with an internally isolated mounting tab. Key electrical characteristics include a maximum RMS on-state current of 16 A at a case temperature of 130 °C, a non-repetitive surge peak on-state current of 200 A at 60 Hz, and a gate trigger current (IGT) maximum of 50 mA. The junction-to-case thermal resistance is 0.90 °C/W, supporting operation within a junction temperature range of -40 °C to +150 °C.

Feature Summary

• High temperature capability with a maximum operating junction temperature of 150 °C
• Internally isolated TO-263 package providing enhanced isolation voltage and heat sinking
• Robust surge handling capability with 200 A peak non-repetitive on-state current
• Designed for high commutation requirements in inductive load applications

Applications

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

Procurement Notes

Verify the specific package variant during procurement, as the QJxx16xHx series includes both leaded (TO-220L/R) and surface-mount (TO-263/N) options. Confirm that the selected component matches the required voltage rating and gate sensitivity for the target circuit design. Ensure compliance with RoHS directives and UL 1557 recognition if electrical isolation is mandated by the application standards.

Selection Notes

Select the QJ6016NH5RP when a surface-mount TRIAC with internal isolation is required for high-temperature AC switching. The 600 V rating suits standard mains voltage applications, while the 50 mA gate sensitivity offers moderate drive requirements. Consider the 0.90 °C/W thermal resistance for heatsinking calculations and ensure the PCB layout accommodates the D²-PAK footprint and isolation creepage distances specified in the datasheet.

Part Context

The QJ6016NH5RP belongs to the QJxx16xHx series of 16 Amp High Temperature Alternistor Triacs manufactured by Littelfuse (formerly IXYS). This series is engineered to facilitate easier thermal management and provide higher surge handling capabilities compared to standard TRIACs. The 'N' suffix denotes the TO-263 (D²-PAK) surface-mount package, distinguishing it from the TO-220 variants available in the same family.

Replacement Considerations

Direct replacements must match the 16 A current rating, 600 V blocking voltage, and TO-263 package form factor. Verify that alternative components support operation in Quadrants I, II, and III and possess comparable dv/dt ratings for inductive loads. Ensure the substitute part maintains similar thermal resistance and isolation voltage specifications to preserve the original design's safety margins.
