Q4025NH6TP

Triacs Overview

The Littelfuse Q4025NH6TP is a bidirectional triac designed for AC power control applications. It features an RMS on-state current (It RMS) of 25 A and a rated repetitive peak off-state voltage (VDRM) of 400 V. The device operates within a temperature range of -40°C to +125°C and utilizes an SMTO-263-2 surface-mount package. Key electrical parameters include a maximum holding current (Ih) of 100 mA, a gate trigger voltage (Vgt) of 2.5 V, and a gate trigger current (Igt) of 80 mA. Non-repetitive peak on-state currents are specified at 208 A and 250 A, with an on-state voltage of 1.8 V and a leakage current of 10 uA.

Triacs Feature Summary

• High thermal tolerance supporting operation up to +125°C
• Surface-mount construction for automated PCB assembly
• Integrated isolation capabilities for main terminal mounting

Triacs Applications

• AC motor speed control systems
• Solid-state relay circuits
• Lighting dimmer controls

Triacs Procurement Notes

Verify the specific suffix 'H6TP' against the manufacturer's latest datasheet to confirm pinout orientation and isolation ratings. Ensure the ordering quantity aligns with the standard tube packaging configuration. Confirm RoHS compliance status directly from the official documentation before finalizing procurement specifications.

Triacs Selection Notes

Select this component when a 25 A RMS current rating and 400 V blocking voltage are required in a surface-mount form factor. The 80 mA gate trigger current necessitates appropriate driver circuitry design. Compare the SMTO-263-2 package dimensions against available board space constraints during the initial schematic capture phase.

Triacs Part Context

This part belongs to the Qxx25xxHx series of high-temperature triacs from Littelfuse. The series is engineered for robust performance in demanding AC switching environments. The H6TP designation indicates specific packaging and isolation characteristics distinct from through-hole or lower-temperature variants within the broader product family.

Triacs Replacement Considerations

Cross-reference with Q4025N5TP for similar electrical ratings but different gate sensitivity. Verify pin compatibility with Q4025J6TP if isolation requirements differ. Always validate thermal dissipation characteristics against the original design intent when substituting.
