Q8025R6TP

Triacs Overview

The Littelfuse Q8025R6TP is a bidirectional triac thyristor designed for AC power control applications. It features an RMS on-state current of 25 A and a rated repetitive off-state voltage (VDRM) of 800 V. The device exhibits a maximum on-state voltage of 1.8 V and a non-repetitive peak on-state current capability of 250 A. Gate triggering parameters include a maximum holding current of 80 mA, a gate trigger voltage of 1.3 V, and a gate trigger current of 80 mA. It operates within a temperature range of -40°C to +150°C and is housed in a TO-220-2 package.

Triacs Feature Summary

• High thermal stability with a maximum junction operating temperature of +150°C
• Robust surge handling capability with a 250 A non-repetitive peak on-state current rating
• Sensitive gate drive requirements facilitating direct interface with logic circuits

Triacs Applications

• AC motor speed control systems
• Solid-state relay implementations
• General purpose AC power switching loads

Triacs Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Littelfuse or authorized distributors before integration. Confirm that the TO-220-2 lead configuration matches the target PCB footprint design. Ensure thermal management solutions accommodate the specified 150°C maximum junction temperature limit during operation.

Triacs Selection Notes

Select this component when an 800 V blocking voltage and 25 A continuous current capacity are required in a standard two-terminal TO-220 form factor. Compare the 80 mA holding current against load characteristics to prevent unintended turn-off during low-current phases. Validate that the 1.3 V gate trigger threshold aligns with the available driver output voltage levels.

Triacs Part Context

This part belongs to the Littelfuse Teccor series of general-purpose triacs. It shares the 25 A / 800 V electrical class with variants like the Q8025L6TP but utilizes a different pinout configuration. The R-series designation typically indicates a specific terminal arrangement distinct from L-series counterparts within the same family.

Triacs Replacement Considerations

Direct functional substitutes include the Q8025L6TP, provided the TO-220-2 pinout compatibility is verified. Other 25 A / 800 V triacs in TO-220 packages may serve as alternatives if gate sensitivity and holding current specifications meet the circuit requirements.
