Q4025NH6RP

Triacs Overview

The Littelfuse Q4025NH6RP is a bidirectional triac in the Qxx25xxHx series, designed for surface mount applications. It features an RMS on-state current of 25 A and a rated repetitive off-state voltage (VDRM) of 400 V. The device exhibits a maximum holding current of 100 mA, with gate trigger parameters specified at 2.5 V and 80 mA. Non-repetitive on-state currents are rated at 208 A and 250 A. It operates within a temperature range of -40°C to +125°C and utilizes an SMTO-263-2 package.

Triacs Feature Summary

• High thermal stability enabled by high-temperature design suitable for demanding environments
• Surface mount construction optimized for automated assembly processes
• Robust surge handling capability defined by specific non-repetitive current ratings

Triacs Applications

• Solid state relay implementations requiring compact form factors
• Industrial motor control circuits utilizing surface mount technology
• General purpose AC power switching applications

Triacs Procurement Notes

Verify component authenticity through official Littelfuse channels or authorized distributors. Confirm that the received parts match the Q4025NH6RP designation and exhibit no physical damage. Ensure storage conditions remain within specified limits to maintain reliability before installation.

Triacs Selection Notes

Select this component when a 400 V rating and 25 A continuous current capacity are required in a surface mount configuration. Compare gate trigger requirements against available drive circuitry to ensure compatibility with the 80 mA specification. Evaluate thermal management needs relative to the SMTO-263-2 package constraints.

Triacs Part Context

This part belongs to the Qxx25xxHx family of high-temperature triacs from Littelfuse. It shares the 25 A current class with other variants but distinguishes itself through its specific voltage rating and surface mount packaging. The H suffix indicates enhanced thermal performance characteristics compared to standard industrial grades.

Triacs Replacement Considerations

Direct substitutes include Q4025N5RP and Q4025R5, though these differ in package type or gate sensitivity. Verify pinout compatibility and thermal resistance values when considering alternative packages such as TO-220 or different SMD formats.
