Q2025L6

Triacs Overview

The Littelfuse Q2025L6 is a bidirectional TRIAC housed in a TO-220 package for through-hole mounting. It features a 400V repetitive peak reverse voltage rating and a 25A RMS on-state current capability. The device supports a 250A surge current rating and operates within a temperature range of -25°C to +125°C. Key electrical parameters include a maximum gate trigger current of 80mA, a maximum gate trigger voltage of 2.5V, and a holding current of 50mA. It has a three-pin configuration with an isolated case connection.

Triacs Procurement Notes

Verify the specific manufacturer datasheet for the Q2025L6 to confirm exact pinout orientation and mechanical dimensions against your PCB footprint requirements. Ensure that the selected component meets all relevant safety certifications required for your final equipment assembly, as compliance status may vary by production batch or regional manufacturing standards.

Triacs Selection Notes

Select this component when a 400V blocking voltage and 25A continuous current capacity are required in a standard through-hole format. Consider the 80mA gate trigger current limit when designing the drive circuitry to ensure reliable turn-on under varying load conditions and temperature extremes without exceeding the specified gate power dissipation limits.

Triacs Part Context

This part belongs to the Littelfuse Alternistor family of TRIACs, designed for high-reliability industrial and consumer applications. The Q-series typically denotes specific voltage and current ratings within the broader portfolio of phase control devices offered by the manufacturer for managing AC loads efficiently.

Triacs Replacement Considerations

Cross-reference with other 400V, 25A TO-220 TRIACs from manufacturers such as STMicroelectronics or Vishay. Verify that any substitute matches the 80mA Igt max and 50mA Ih specifications to maintain compatibility with existing gate drive circuits.
