Q6025LH5TP

Triacs Overview

The Littelfuse Q6025LH5TP is a high-temperature Bidirectional Triac designed for robust power switching applications. It features a rated repetitive off-state voltage (VDRM) of 600 V and an on-state RMS current (ITRMS) of 25 A. The device operates within a junction temperature range of -40 °C to +150 °C, ensuring reliability in demanding thermal environments. Key electrical parameters include a maximum holding current of 50 mA, a gate trigger voltage of 1.3 V, and a gate trigger current of 50 mA. The on-state voltage is specified at 1.8 V, with a leakage current of 10 µA under rated voltage conditions.

Triacs Feature Summary

• High-temperature operation capability up to 150 °C
• Isolated TO-220AB package for enhanced thermal management
• Sensitive gate design for direct microprocessor interfacing

Triacs Applications

• Industrial motor speed control systems
• Solid-state relay modules
• High-temperature lighting dimmers

Triacs Procurement Notes

Verify the specific suffix LH5TP against official Littelfuse documentation to confirm the isolated package variant and high-temperature rating. Ensure compatibility with existing thermal management designs due to the TO-220AB form factor. Cross-reference datasheet revisions to confirm pinout consistency before integration into production assemblies.

Triacs Selection Notes

Select this component when applications require 600 V blocking capability combined with 25 A continuous current handling in elevated temperature environments. The sensitive gate characteristics simplify drive circuit design compared to standard gate devices. Verify that the system's dv/dt requirements are met by the device's critical rate of rise of off-state voltage specifications.

Triacs Part Context

This part belongs to the QJ/Qxx25xHx series of high-temperature triacs from Littelfuse. It shares core electrical ratings with similar models but distinguishes itself through the LH5TP designation, indicating specific packaging and thermal performance attributes tailored for industrial durability.

Triacs Replacement Considerations

Direct substitutes may include other 600V 25A high-temperature triacs in TO-220 packages. Verify gate sensitivity and holding current limits to ensure circuit stability. Check manufacturer-specific thermal resistance values if replacing with non-Littelfuse components.
