Q8025N5TP

Triacs Overview

The Littelfuse Q8025N5TP is a bidirectional triac 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 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 of 100 mA, a gate trigger voltage of 2.5 V, and a gate trigger current of 50 mA. Non-repetitive peak on-state currents are specified at 167 A and 200 A, with an on-state voltage of 1.8 V and a leakage current of 10 uA.

Triacs Feature Summary

• Bidirectional switching capability for AC load control
• Surface-mount construction in an SMTO-263-2 package
• High thermal stability up to 125°C junction temperature

Triacs Applications

• AC motor speed control circuits
• Solid-state relay designs
• Lighting dimmer modules

Triacs Procurement Notes

Verify the specific Littelfuse datasheet for the Q8025N5TP to confirm RoHS compliance status and REACH SVHC declarations prior to integration. Ensure that the ordering suffix matches the required packaging format, as variations may exist between tube and reel configurations. Cross-reference the manufacturer's official documentation to validate the exact pinout and mechanical dimensions against the target PCB footprint.

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. Compare the 50 mA gate trigger current against available driver capabilities to ensure sufficient drive strength. Evaluate the SMTO-263-2 package thermal resistance against the expected heat dissipation requirements of the application environment.

Triacs Part Context

This part belongs to the Littelfuse Qxx25xx series of triacs, which provides standardized high-current solutions for industrial and consumer electronics. The Q8025N5TP specifically addresses the need for robust AC switching in compact printed circuit board layouts, offering a reliable alternative to through-hole alternatives like the Q8025K6TP or Q8025L6TP.

Triacs Replacement Considerations

Direct substitutes within the same series include the Q8025J6TP and Q8025K6TP, though these utilize through-hole packages (SMTO-218). For surface-mount compatibility, verify if the QJ8025NH5RP meets the specific gate current and thermal requirements, noting its different package type and operating temperature limits.
