Q8025NH5TP

Triacs Overview

The Littelfuse Q8025NH5TP is a bidirectional triac in the Qxx25xxHx series, housed in an SMTO-263-2 surface-mount package. It supports an RMS on-state current of 25 A and withstands a rated repetitive off-state voltage of 800 V. The device exhibits a maximum non-repetitive peak on-state current of 250 A and a low on-state voltage of 1.8 V. Gate triggering requires a maximum voltage of 1.3 V and current of 50 mA, with a maximum holding current of 50 mA. Leakage current at VDRM is limited to 10 uA. It operates within a temperature range of -40 C to +125 C.

Triacs Feature Summary

• Sensitive gate architecture enabling direct interfacing with microprocessors via low trigger requirements.
• High surge capability supporting 250 A non-repetitive peak currents for robust circuit protection.
• Surface-mount construction designed for automated assembly and integration into compact PCB layouts.

Triacs Applications

• Solid-state relays requiring high isolation and switching capabilities.
• AC motor speed control circuits for industrial or consumer appliances.
• Lighting dimmer applications utilizing sensitive gate triacs.

Triacs Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm RoHS compliance status through current documentation as regulatory updates may occur. Ensure storage conditions maintain integrity prior to soldering. Validate package orientation and pinout alignment during assembly to prevent installation errors.

Triacs Selection Notes

Select this component when an 800 V blocking voltage and 25 A continuous current rating are required in a surface-mount form factor. The sensitive gate specification (50 mA max) facilitates drive from standard logic outputs. Compare thermal resistance values against system heat dissipation requirements to ensure junction temperatures remain within the specified operational limits during conduction cycles.

Triacs Part Context

This part belongs to the Littelfuse Qxx25xxHx series of high-performance triacs. The 'H' suffix typically denotes specific gate sensitivity characteristics within the family. It shares core electrical ratings with other variants like the Q8025J6TP but differs in packaging and precise gate parameters, necessitating careful substitution analysis based on exact application constraints.

Triacs Replacement Considerations

Direct substitutes include the Q8025J6TP and Q8025K6TP, though these utilize through-hole packages (SMTO-218). Verify that the alternative package fits the board layout and that gate trigger currents match the driving circuit capabilities before implementation.
