QV6025LH5TP

Triacs Overview

The QV6025LH5TP is a high-temperature Alternistor TRIAC manufactured by Littelfuse, rated for 25 A RMS on-state current and available in 600 V or 800 V blocking voltage options. It features a maximum junction temperature of 150°C and supports operation in quadrants I, II, and III with a gate trigger current of 50 mA. The device utilizes internally isolated TO-220 packaging to provide enhanced isolation voltage and thermal management capabilities.

Triacs Feature Summary

• High dv/dt immunity up to 2000 V/μs for improved noise resistance
• Internally isolated TO-220 package for higher isolation voltage
• 3Q technology enabling high commutation capability without snubber circuits

Triacs Applications

• Heater control systems including coffee brewers and tankless water heaters
• AC solid-state relays
• Light dimmers for incandescent and LED lighting
• Motor speed control in kitchen appliances and power tools

Triacs Procurement Notes

Verify the specific voltage rating (600 V or 800 V) required for the application, as both are available within this series designation. Confirm that the internal isolation of the TO-220 package meets the safety requirements for the intended circuit design. Ensure compatibility with the 50 mA gate trigger sensitivity for the driving circuitry.

Triacs Selection Notes

Select this component when high commutation capability is needed for inductive loads without external snubber circuits. The internally isolated package is suitable for applications requiring higher isolation voltage between the mounting tab and electrical terminals. Verify that the operating environment allows for a maximum junction temperature of 150°C.

Triacs Part Context

This part belongs to the QVxx25xHx series of 25 A high-temperature Alternistor TRIACs from Littelfuse. The series includes variants with different voltage ratings and gate sensitivities, packaged in TO-220AB (isolated and non-isolated) and TO-263 configurations. The QV prefix denotes high dv/dt performance characteristics.

Triacs Replacement Considerations

Direct substitutes include other parts within the QVxx25xHx series such as QV6025LH4TP for lower gate sensitivity or QV8025LH5TP for higher voltage ratings. Cross-manufacturer replacements require matching the 25 A RMS current, 600 V/800 V blocking voltage, and internally isolated TO-220 package constraints.
