QV6025NH5RP

Triacs Overview

The QV6025NH5RP is a high-temperature Alternistor TRIAC from the QVxx25xHx series, manufactured by Littelfuse. It features a 25 A on-state RMS current rating and is available in 600 V or 800 V blocking voltage options. The device operates in quadrants I, II, and III with a gate trigger current of 50 mA. It utilizes a TO-263 (D2PAK) surface-mount package with an isolated tab. Key electrical characteristics include a peak on-state voltage of 1.50 V at 35.4 A, a maximum junction temperature of 150°C, and a non-repetitive surge current capability of 250 A at 60 Hz.

Triacs Feature Summary

• High dv/dt immunity up to 2000 V/μs for improved noise resistance
• 3Q technology enabling high commutation capability without snubber circuits
• Internally isolated TO-263 package for enhanced heat sinking and isolation

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 the base part number covers both variants. Confirm the package type matches the design requirements, ensuring compatibility with the TO-263 footprint. Check for RoHS compliance and halogen-free status if environmental regulations apply. Validate thermal management solutions against the specified junction temperature limits.

Triacs Selection Notes

Select this component for applications requiring high commutation capability with inductive loads. Ensure the circuit design accommodates the 50 mA gate trigger current. Consider the thermal resistance values for proper heatsinking. Verify that the operating environment stays within the -40°C to 150°C junction temperature range. Evaluate the need for internal isolation versus non-isolated packages based on safety requirements.

Triacs Part Context

This device belongs to the QVxx25xHx series of 25 A high-temperature Alternistor TRIACs. The series includes variations in voltage ratings (600 V/800 V), gate sensitivity (35 mA/50 mA), and packages (TO-220/TO-263). The QV prefix denotes high dv/dt performance, while the NH5 suffix specifies the TO-263 package and 50 mA gate sensitivity.

Triacs Replacement Considerations

Direct replacements within the same series include QV6025NH4 (35 mA sensitivity) or QV8025NH5 (800 V rating). Cross-brand equivalents should be evaluated for matching current, voltage, and package dimensions.
