Q6025L6

Triacs Overview

The Littelfuse Q6025L6 is a bidirectional triac rated for 600 V repetitive peak off-state voltage and 25 A RMS on-state current. It features an 80 mA maximum DC gate trigger current and maintains a low on-state voltage of 1.8 V. The device operates within a junction temperature range of -40 °C to +125 °C, with a maximum holding current of 100 mA. Packaged in an isolated TO-220AB configuration, it provides electrical isolation between the terminal and the mounting base.

Triacs Feature Summary

• Alternistor technology designed for high reliability and robust performance in power control applications
• Integrated electrical isolation between the main terminals and the mounting flange for simplified heat sinking
• Sensitive gate structure enabling direct interfacing with standard logic circuits

Triacs Applications

• Solid state relays and motor speed controllers
• Lighting dimmers and phase control circuits
• General purpose AC power switching

Triacs Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm package type and isolation status. Datasheets may list variations such as Q6025L6TP or Q6025R5; ensure the exact part number matches the required thermal and mechanical specifications before procurement.

Triacs Selection Notes

Select this component when a 600 V blocking capability and 25 A continuous load handling are required. The isolated TO-220 package facilitates direct mounting to heatsinks without additional insulators. Verify that the gate drive circuit can supply at least 80 mA to ensure reliable triggering across the specified temperature range.

Triacs Part Context

This device belongs to the Littelfuse Alternistor family, which utilizes advanced silicon processing to enhance surge current capability and dv/dt immunity compared to standard triacs. The Q6025 series specifically targets industrial applications requiring durable AC switching solutions.

Triacs Replacement Considerations

Q6025L6TP: Identical electrical characteristics with a through-hole tube packaging variant. Q6025NH6RP: Surface mount alternative with similar ratings but different thermal management requirements.
