QV8025NH5RP

Triacs Overview

The Littelfuse QV8025NH5RP is a bidirectional triac designed for high-temperature and high dv/dt applications. It features an RMS on-state current of 25 A and a non-repetitive peak on-state current of 250 A. The device supports a rated repetitive off-state voltage (VDRM) of 800 V with an on-state voltage of 1.5 V. Gate triggering parameters include a maximum holding current of 75 mA, a gate trigger voltage of 1.3 V, and a gate trigger current of 50 mA. It operates within a temperature range of -40°C to +150°C and is housed in a TO-263AB-3 surface-mount package.

Triacs Feature Summary

• Engineered for high-temperature operation up to 150°C
• High dv/dt capability for robust switching performance
• Surface-mount TO-263AB-3 packaging for automated assembly

Triacs Applications

• Industrial motor control systems
• Solid-state relay modules
• High-power lighting dimmers

Triacs Procurement Notes

Verify the specific suffix 'RP' against official Littelfuse documentation to confirm reel packaging requirements. Ensure the selected variant matches the required thermal management specifications for the target application environment. Cross-reference the datasheet revision date to validate parameter accuracy before finalizing component selection.

Triacs Selection Notes

Select this component when high junction temperature tolerance and rapid voltage change immunity are critical design constraints. Compare the 1.5 V on-state voltage drop against alternative triacs to evaluate conduction losses. Confirm that the TO-263AB-3 footprint aligns with the PCB layout and that the 25 A RMS rating satisfies the continuous load requirements of the circuit.

Triacs Part Context

This part belongs to the QVxx25xHx series from Littelfuse, which specializes in high-performance thyristors. The series is characterized by enhanced thermal stability and switching robustness compared to standard triacs. It serves as a specialized solution for demanding power electronics environments where reliability under stress conditions is paramount.

Triacs Replacement Considerations

Direct substitutes may include other 800V 25A TO-263 triacs from Littelfuse or competitors, provided they match the 150°C max operating temperature and similar gate trigger characteristics. Verify pinout compatibility and thermal resistance values before substitution.
