Q8025LH5TP

Triacs Overview

The Littelfuse Q8025LH5TP 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 rated repetitive off-state voltage of 800 V. The device supports a non-repetitive peak on-state current of 250 A 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. Operating temperatures range from -40°C to +150°C. It utilizes a TO-220-3 Insulated through-hole package.

Triacs Feature Summary

• High temperature capability up to 150°C
• High dv/dt rating for robust switching
• Insulated TO-220-3 package for thermal management

Triacs Applications

• Industrial motor control systems
• Solid state relays
• High power AC switching circuits

Triacs Procurement Notes

Verify the specific suffix 'H5TP' against the manufacturer's official datasheet to confirm insulation class and pinout configuration. Ensure the ordered component matches the required 800V blocking voltage and 25A continuous current ratings for the target application environment. Cross-reference the package type to guarantee mechanical compatibility with existing heat sink and PCB layouts.

Triacs Selection Notes

Select this component when high thermal stability and fast switching speed are critical. The 800V rating suits medium-voltage AC loads. Compare gate sensitivity requirements against the 1.3V/50mA specification to ensure driver compatibility. Consider the insulated package for safety isolation needs in mains-connected designs.

Triacs Part Context

This part belongs to the QVxx25xHx series of high-performance triacs. It shares the 25A current handling family with other Littelfuse thyristors but distinguishes itself through enhanced thermal and dv/dt specifications. The TO-220-3 Ins package provides a standardized mounting solution for industrial power electronics.

Triacs Replacement Considerations

Direct substitutes may include other 800V 25A triacs in TO-220-3 packages. Verify equivalent dv/dt ratings and gate trigger characteristics before substitution. Check for identical insulation requirements if replacing in safety-critical circuits.
