Q8025L6TP

Triacs Overview

The Littelfuse Q8025L6TP is a three-terminal bidirectional triac designed for high-power switching applications. It features an RMS on-state current rating of 25 A and supports non-repetitive peak on-state currents of 250 A. The device offers a rated repetitive off-state voltage (VDRM) of 800 V with a maximum off-state leakage current of 10 uA under VDRM conditions. Key gate parameters include a gate trigger voltage (Vgt) of 2.5 V and a gate trigger current (Igt) of 80 mA. The component exhibits a maximum holding current (Ih) of 50 mA and a typical on-state voltage of 1.4 V. It operates within a temperature range of -25°C to +125°C and is housed in a TO-220 package.

Triacs Feature Summary

• High thermal robustness with a maximum junction operating temperature of 125°C
• Sensitive gate triggering capability with defined Vgt and Igt thresholds
• Low on-state voltage drop for efficient power conduction
• Robust surge handling with 250 A non-repetitive peak current capacity

Triacs Applications

• Industrial motor control systems
• Solid-state relays and contactors
• AC power regulation circuits

Triacs Procurement Notes

Verify the specific suffix 'L6' against the manufacturer datasheet to confirm the exact gate trigger current specifications, as variations exist within the Q series. Ensure the ordering documentation explicitly lists the TO-220 through-hole package configuration. Cross-reference the RoHS compliance status directly with the official Littelfuse product page or latest data sheet revision before finalizing procurement orders.

Triacs Selection Notes

Select this component when an 800 V blocking voltage and 25 A continuous current are required in a standard TO-220 footprint. The 80 mA gate trigger current necessitates a driver capable of sourcing sufficient current, distinguishing it from lower-gate-sensitivity variants. Verify that the application's thermal management can sustain the 125°C maximum junction temperature limit during continuous operation.

Triacs Part Context

This part belongs to the Littelfuse Qxx25xx series of high-current triacs. It shares the 25 A RMS current rating with other members like the Q8025N5TP but differs in package style and gate sensitivity. The TO-220 form factor distinguishes it from surface-mount alternatives such as the Q8025NH5TP, providing a solution for through-hole PCB designs requiring higher mechanical stability.

Triacs Replacement Considerations

Direct pin-compatible replacements within the same series include the Q8025N5TP, though gate trigger characteristics differ. For equivalent voltage and current ratings in a different package, consider the QV8025LH5TP for through-hole mounting with enhanced dv/dt immunity.
