Q6025LH5

Triacs Overview

The Littelfuse Q6025LH5 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 current of 50 mA, and a gate trigger voltage of 1.3 V. The component exhibits a low on-state voltage of 1.8 V and a leakage current of 10 µA at VDRM. Packaged in an isolated TO-220AB through-hole configuration, it provides effective thermal management and electrical isolation.

Triacs Feature Summary

• High-temperature operation capability up to 150°C for enhanced durability
• Isolated TO-220AB package design for improved thermal dissipation and safety
• Sensitive gate structure allowing direct interfacing with standard logic circuits

Triacs Applications

• Solid-state relays requiring high thermal stability
• Industrial motor control systems
• Lighting dimmer circuits

Triacs Procurement Notes

Verify the exact suffix against official Littelfuse documentation, as variations such as TP or R5 may indicate different packaging or specific manufacturing lot characteristics. Confirm RoHS compliance status directly from the manufacturer's datasheet before procurement. Ensure the isolated package variant matches the thermal and electrical isolation requirements of the target circuit design.

Triacs Selection Notes

Select this component when a 600V rating and 25A continuous current capacity are required alongside extended high-temperature performance. The sensitive gate specifications facilitate easier drive circuit design compared to standard gate devices. Consider the TO-220AB footprint for PCB layout constraints and verify that the 50 mA holding current meets the minimum load requirements of the application.

Triacs Part Context

This part belongs to the Littelfuse Q series of thyristors, specifically engineered for general-purpose AC power control. The 'L' designation typically indicates an isolated package variant, while 'H' denotes high-temperature capability. This series complements other Littelfuse triacs by offering a balance of high current handling and thermal resilience in a standard through-hole form factor.

Triacs Replacement Considerations

The Q6025LH5TP is a verified equivalent part number representing the same electrical specifications with tube packaging. Designers should verify pinout compatibility and thermal resistance values when substituting with non-isolated variants like the Q6025R5.
