Q8025RH5TP

Triacs Overview

The Littelfuse Q8025RH5TP is a bidirectional triac designed for high-reliability AC power control applications. It features an RMS on-state current of 25 A and a rated repetitive peak off-state voltage (VDRM) of 800 V. The device operates within a junction temperature range of -40 °C to +125 °C. Key electrical parameters include a maximum holding current of 70 mA, a gate trigger voltage of 2.5 V, and a gate trigger current of 50 mA. It exhibits a typical on-state voltage of 1.6 V and a low off-state leakage current of 10 µA at VDRM. The component is housed in a TO-220-2 package with a flange mount style, weighing approximately 2.2 g.

Triacs Feature Summary

• High thermal stability supporting operation up to +125 °C
• Robust 800 V blocking capability for industrial AC loads
• Low gate sensitivity facilitating direct driver interface

Triacs Applications

• Industrial motor speed control systems
• Solid-state relay modules
• AC power regulation circuits

Triacs Procurement Notes

Verify the specific suffix RH5TP against the manufacturer's latest datasheet to confirm pinout and isolation ratings. Ensure the ordering quantity aligns with the standard tube packaging configuration provided by authorized distributors. Cross-reference the RoHS compliance status with current environmental regulations before finalizing procurement orders.

Triacs Selection Notes

Select this component when an 800 V rating and 25 A continuous current are required in a through-hole TO-220-2 form factor. Compare the 70 mA holding current against load requirements to prevent unintended turn-off. Verify that the 1.6 V on-state voltage meets thermal dissipation constraints for the specific heatsinking arrangement.

Triacs Part Context

This part belongs to the Littelfuse Q-series thyristor family, which provides standardized solutions for AC switching. The Q8025RH5TP shares the core 25 A / 800 V architecture with other variants like the Q8025N5TP but differs in package type and specific gate characteristics. It serves as a direct replacement for legacy TO-220-2 triacs in existing designs requiring equivalent electrical performance.

Triacs Replacement Considerations

Direct replacements include the Q8025J6TP for isolated mounting needs or the Q8025R5 for general-purpose applications. Verify pin compatibility and thermal resistance values when substituting with similar 25 A/800 V triacs from other manufacturers.
