Q4025L6TP

Triacs Overview

The Littelfuse Q4025L6TP is a three-terminal triac designed for general-purpose AC power control applications. It features a TO-220 package with through-hole mounting and supports an RMS on-state current of 25 A. The device has a rated repetitive peak off-state voltage (VDRM) of 400 V and a non-repetitive surge current rating of 250 A. Key electrical parameters include a maximum gate trigger current (Igt) of 80 mA, a gate trigger voltage (Vgt) of 2.5 V, and a holding current (Ih) of 50 mA. The component operates within a temperature range of -25°C to +125°C.

Triacs Feature Summary

• Three-terminal bidirectional thyristor structure for AC switching
• High thermal stability with operating temperatures up to 125°C
• Robust surge current handling capability for inductive loads

Triacs Applications

• General purpose AC motor speed control
• Solid state relays
• Lighting dimmer circuits

Triacs Procurement Notes

Verify the specific suffix L6TP against official Littelfuse documentation to confirm pinout configuration and isolation requirements. Ensure the selected distributor provides traceable components from authorized channels to guarantee authenticity and compliance with RoHS standards.

Triacs Selection Notes

Select this component when a 400 V blocking voltage and 25 A continuous current capacity are required in a standard TO-220 footprint. Consider the 80 mA gate drive requirement for driver circuit design. Verify that the thermal management solution can handle the power dissipation at the expected ambient temperature and load conditions.

Triacs Part Context

This part belongs to the Littelfuse Q4025 series of high-current triacs. The series offers various voltage ratings and package options to suit different power control needs. The Q4025L6TP specifically utilizes the TO-220 package, distinguishing it from surface-mount variants like the SMTO-263 or isolated versions found in other series members.
