QV6025RH5TP

Triacs Overview

The QV6025RH5TP is a high temperature Alternistor TRIAC from the QVxx25xHx series, manufactured by Littelfuse. It features an internally-isolated TO-220 package with a non-isolated mounting tab configuration (R-package). The device supports a maximum junction temperature of 150°C and offers a blocking voltage of 600 V. Key electrical parameters include an on-state RMS current of 25 A at a case temperature of 125°C, a peak on-state voltage of 1.50 V at 35.4 A, and a DC gate trigger current of 50 mA in quadrants I, II, and III. It provides a critical rate-of-rise of off-state voltage (dv/dt) up to 2000 V/μs.

Triacs Feature Summary

• Internally isolated TO-220 package design for improved heat sinking and higher isolation voltage
• High dv/dt capability up to 2000 V/μs for enhanced noise immunity
• 3Q technology enabling operation in quadrants I, II, and III without snubber circuits
• Mechanically and thermally robust assembly suitable for high surge handling

Triacs Applications

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

Triacs Procurement Notes

Verify component authenticity through authorized Littelfuse distributors or certified suppliers. Confirm the specific R-package variant matches the required internal isolation specifications. Check RoHS compliance status and ensure the ordering suffix corresponds to the correct tube pack quantity of 1000 units. Validate datasheet revisions against the manufacturing date code.

Triacs Selection Notes

Select this component for AC power control applications requiring high commutation capability and thermal management. The 600 V rating suits standard mains voltage applications. Ensure the circuit design accommodates the 50 mA gate trigger current. Consider the 150°C maximum junction temperature for high-temperature environments. Verify that the TO-220 isolated package fits the mechanical constraints of the heat sink interface.

Triacs Part Context

This part belongs to the QVxx25xHx series of 25 A high temperature Alternistor TRIACs. The series includes variants with different voltage ratings (600 V or 800 V), gate sensitivities (35 mA or 50 mA), and packages (TO-220AB L/R or TO-263). The QV prefix denotes high dv/dt performance, while the H5 suffix indicates 50 mA gate sensitivity.

Triacs Replacement Considerations

Direct substitutes within the same series include QV6025LH5TP (isolated TO-220 L-package) and QV6025NH5TP (TO-263 SMT package). Cross-series replacements like QJ6025RH5TP exist but lack internal isolation and differ in holding current characteristics.
