Q8025J6TP

Triacs Overview

The Littelfuse Q8025J6TP is a bidirectional triac from the Qxx25xx series, designed for high-power switching applications. It features an RMS on-state current (It RMS) of 25 A and a rated repetitive off-state voltage (VDRM) of 800 V. The device operates within a temperature range of -40°C to +125°C and utilizes an SMTO-218 through-hole package. Key electrical parameters include a maximum holding current (Ih) of 100 mA, gate trigger voltage (Vgt) of 2.5 V, and 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-voltage blocking capability suitable for demanding AC power control environments
• Sensitive gate structure allowing direct interfacing with standard logic circuits
• Robust thermal performance supporting operation up to 125°C junction temperature

Triacs Applications

• Industrial motor speed control systems
• Solid-state relays for AC load switching
• Lighting dimmer circuits for commercial fixtures

Triacs Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number Q8025J6TP with official Littelfuse documentation. Confirm that the received units match the specified SMTO-218 package and electrical ratings. Ensure compliance with RoHS and REACH standards as indicated in the product specifications before integration into final assemblies.

Triacs Selection Notes

Select this component when an 800 V rating is required for AC switching duties. The 25 A RMS current capacity supports moderate to high-power loads. Verify that the gate trigger requirements align with the driving circuit's output capabilities. Consider the SMTO-218 package constraints for PCB layout and thermal management solutions during the design phase.

Triacs Part Context

This triac belongs to the Qxx25xx family, which shares common characteristics such as the 25 A current rating and sensitive gate technology. Variants within this series typically differ primarily in their voltage blocking capabilities, such as 400 V or 800 V options. The Q8025J6TP specifically addresses applications requiring higher voltage isolation while maintaining the same current handling and package form factor.

Triacs Replacement Considerations

Direct substitutes may include other 800 V, 25 A triacs in the SMTO-218 package from Littelfuse or compatible manufacturers. Verify pinout compatibility and ensure that gate sensitivity and thermal resistance parameters meet or exceed the original specifications.
