Q6010LT

Triacs Overview

The Littelfuse Q6010LT is a silicon-controlled switch (SCR) rated for 600V repetitive peak off-state voltage and 10A RMS on-state current. It utilizes a TO-220AB package with three leads for through-hole mounting. The device supports a non-repetitive surge current of 100A at 8.3ms and 120A at 10ms. Gate trigger characteristics include a maximum gate trigger voltage of 2.5V and a maximum gate trigger current of 75mA. Leakage current in the off-state is limited to 50µA at rated voltage. Operating temperatures range from -40°C to +125°C junction temperature.

Triacs Feature Summary

• High thermal stability with a maximum junction temperature of 125°C
• Robust surge handling capability for industrial switching loads
• Sensitive gate drive requirements for direct microprocessor interfacing

Triacs Applications

• Industrial motor control circuits
• Solid-state relay implementations
• AC power regulation systems

Triacs Procurement Notes

Verify the specific suffix against the manufacturer datasheet to confirm pinout configuration and thermal pad specifications. Ensure the selected variant matches the required gate sensitivity for the target driver circuit. Cross-reference the package outline drawing to validate mechanical fit within the enclosure design constraints.

Triacs Selection Notes

Select this component when a latching output is required rather than continuous conduction typical of triacs. Evaluate the thermal resistance of the heatsink interface to maintain junction temperature within limits during high-duty cycle operations. Confirm that the load current does not exceed the 10A RMS rating under worst-case ambient conditions.

Triacs Part Context

This part belongs to the Qxx10 series of silicon-controlled switches designed for general purpose power control. It serves as a robust alternative to triacs in applications requiring unidirectional current flow or specific latching behavior. The series is engineered for reliability in harsh electrical environments common in industrial automation.

Triacs Replacement Considerations

Direct replacements must match the 600V/10A rating and TO-220 package. Verify gate trigger parameters to ensure compatibility with existing drive circuits. Consider thermal performance differences if substituting with parts from different manufacturers.
