QV8025NH4RP

Triacs Overview

The QV8025NH4RP is a high-temperature, high dv/dt Triac manufactured by Littelfuse Inc. It features an 800 V blocking voltage and a 25 A RMS on-state current rating. The device is housed in a surface-mount TO-263 (D2PAK) package. It supports a surge current capability of 153 A at 60 Hz half-cycle and operates with a maximum junction temperature of +150°C.

Triacs Feature Summary

• High thermal robustness with a maximum junction temperature of +150°C
• High dv/dt sensitivity for reliable switching in noisy environments
• Surface-mount TO-263 (D2PAK) package design for automated assembly

Triacs Applications

• AC power control applications requiring high thermal stability
• Solid-state relays and contactors
• Motor speed control systems

Triacs Procurement Notes

Verify the specific suffix '4' against official Littelfuse documentation to confirm the exact variant specifications. Ensure the TO-263 package footprint matches your PCB layout requirements. Confirm availability status as supply constraints may affect procurement timelines.

Triacs Selection Notes

Select this component when high junction temperature operation up to +150°C is required. The 800 V rating suits medium-voltage AC line applications. The TO-263 package facilitates surface-mount technology integration. Evaluate thermal management needs given the 25 A continuous current rating.

Triacs Part Context

This Triac belongs to the QV series designed for high-temperature and high dv/dt performance. It complements other variants like the QV8025NH5RP within the Littelfuse discrete component portfolio. The series targets robust AC switching solutions for industrial and consumer electronics.

Triacs Replacement Considerations

Check datasheet compatibility for direct pin-to-pin replacements. Verify that alternative Triacs match the 800 V voltage and 25 A current ratings. Ensure the replacement device supports the same TO-263 package and high junction temperature limits.
