QV6016LH5TP

Overview

The QV6016LH5TP is a 16 A high temperature Alternistor TRIAC from the QVxx16xHx series, manufactured by Littelfuse. It features a maximum junction temperature of 150 °C and supports a non-repetitive surge peak on-state current (ITSM) of 200 A at 60 Hz. The device operates in quadrants I, II, and III with a rated repetitive off-state voltage (VDRM/VRRM) of 600 V. It utilizes an internally isolated TO-220 package for enhanced thermal management and isolation. Key electrical parameters include a peak on-state voltage of 1.60 V at 22.6 A, a gate trigger current (IGT) of 50 mA, and a holding current maximum of 60 mA.

Feature Summary

• Internally isolated TO-220 assembly providing mechanical robustness and higher isolation voltage
• High dv/dt capability up to 1000 V/µs for reliable commutation
• Operates in quadrants I, II, and III for versatile AC power control
• Halogen-free and RoHS-compliant construction

Applications

• Heater control systems including coffee brewers and tankless water heaters
• AC solid-state relays requiring high commutation capability
• Light dimmers for incandescent and LED lighting loads
• Motor speed control in kitchen appliances and light industrial compressors

Procurement Notes

Verify the manufacturer designation as Littelfuse despite the IXYS brand query, as official datasheets attribute this component to Littelfuse. Confirm the specific package variant corresponds to the internally isolated TO-220L configuration. Ensure compliance with the stated environmental approvals, including UL 1557 recognition for electrically isolated semiconductor devices.

Selection Notes

Select this component for applications demanding high surge handling and elevated operating temperatures up to 150 °C. The 50 mA gate sensitivity suits standard drive circuits. Consider the internal isolation feature when designing for safety-critical AC switching environments where galvanic separation between the gate and main terminals is required.

Part Context

This part belongs to the QVxx16xHx series of 16 A Alternistor TRIACs. The series includes variants with different gate sensitivities (10 mA to 50 mA) and packages (TO-220L, TO-220R, TO-263). The 'L' suffix denotes the isolated TO-220 package, while 'H5' indicates the 50 mA gate trigger current sensitivity level.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Littelfuse or authorized distributors for direct replacements within the QVxx16xHx family or equivalent high-temperature Alternistor TRIACs.
