QV6025NH5TP

Triacs Overview

The QV6025NH5TP is a high-temperature Alternistor TRIAC from the QVxx25xHx series, manufactured by Littelfuse. It features a TO-263 (D2PAK) surface-mount package with an isolated mounting tab. The device supports a maximum repetitive off-state voltage of 800 V and an RMS on-state current of 25 A at a case temperature of 125 °C. It offers a non-repetitive surge peak on-state current of 250 A for a 60 Hz half-cycle. Key electrical characteristics include a gate trigger current of 50 mA, a peak on-state voltage of 1.50 V, and a critical rate-of-rise of off-state voltage up to 2000 V/μs. The component operates within a junction temperature range of -40 °C to 150 °C.

Triacs Feature Summary

• High dv/dt capability of up to 2000 V/μs for improved noise immunity
• Internally-isolated TO-263 package for better heat sinking and isolation voltage
• 3Q technology enabling operation in quadrants I, II, and III without snubber circuits
• Mechanically and thermally robust assembly suitable for high commutation loads

Triacs Applications

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

Triacs Procurement Notes

Verify the manufacturer designation, as Littelfuse acquired Teccor Electronics. Confirm the specific suffix 'TP' indicates tube packaging per the datasheet packing options table. Ensure the ordering code matches the 800 V rating and 50 mA gate sensitivity required for the application. Cross-reference the part number against the official Littelfuse selector guide to confirm availability and exact package dimensions.

Triacs Selection Notes

Select this component for AC power control applications requiring high surge handling and noise immunity. The 800 V rating suits higher voltage AC lines compared to 600 V variants. The TO-263 package is appropriate for surface-mount designs needing thermal isolation. Consider the 50 mA gate trigger current when designing the drive circuitry. Ensure the PCB layout accommodates the isolated tab for proper heat dissipation and safety clearance.

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-220 or TO-263). The QV prefix denotes high dv/dt performance. The 'N' indicates the TO-263 package, while 'H5' specifies the 50 mA gate sensitivity and 800 V blocking voltage capability.

Triacs Replacement Considerations

Direct replacements within the same series include QV8025NH5TP (same specs, confirmed substitute). Other series members like QV6025NH5TP offer identical electrical performance but with a lower 600 V rating. For pin-compatible alternatives, verify the gate sensitivity and voltage ratings match the original design requirements.
