Q8025R6

Triacs Overview

The Littelfuse Q8025R6 is a bidirectional triac (alternistor) rated for 800 V repetitive peak off-state voltage and 25 A RMS on-state current. It features a gate trigger current of 80 mA and a holding current of 100 mA maximum. The device exhibits an on-state voltage of 1.8 V and leakage current of 10 uA at rated voltage. Designed for through-hole mounting, it utilizes the TO-220AB package and operates within a temperature range of -40 °C to +125 °C.

Triacs Feature Summary

• Bidirectional switching capability for AC phase control applications
• High surge current handling with non-repetitive peak ratings up to 250 A
• Robust thermal performance in standard TO-220AB leaded package

Triacs Applications

• Motor speed control systems
• Temperature modulation circuits
• AC power switching loads

Triacs Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number against official Littelfuse documentation. Ensure the specific suffix matches the required pin configuration and packaging style. Confirm RoHS compliance status if environmental regulations apply to the final assembly. Validate that the procurement source provides traceable manufacturing data sheets.

Triacs Selection Notes

Select this component when an 800 V blocking voltage and 25 A continuous current capacity are required for AC load management. The TO-220AB package facilitates efficient heat dissipation for high-power applications. Consider the 80 mA gate sensitivity for driver circuit compatibility. Evaluate thermal resistance requirements based on the specific ambient operating conditions and duty cycle of the intended application.

Triacs Part Context

This device belongs to the Qxx25xx series of alternistors from Littelfuse. The series offers bidirectional thyristor solutions ranging from 6 A to 40 A with voltages from 200 V to 1000 V. These components are engineered for reliable AC switching in industrial and consumer electronics environments requiring robust solid-state control.

Triacs Replacement Considerations

Compatible substitutes include the Q8025K6TP and Q8025L6TP. Verify package compatibility as the K6TP uses SMTO-218 while the L6TP uses TO-220-2. Ensure electrical parameters such as voltage rating and current handling meet or exceed the original design specifications before substitution.
