Q4015R567

Triacs Overview

The Q4015R567 is a standard TRIAC from the Teccor family, designed for general-purpose AC switching applications. It features a 400 V repetitive peak off-state voltage and a 15 A on-state current rating. The device utilizes a TO-220-3 Non-Isolated Tab package for through-hole mounting. Key electrical parameters include a gate trigger current of 50 mA, a holding current maximum of 70 mA, and an operating temperature range spanning from -40°C to +125°C.

Triacs Feature Summary

• Standard TRIAC configuration suitable for AC power control
• Robust thermal management via non-isolated tab design
• Wide operating temperature range for industrial environments

Triacs Applications

• General purpose AC motor speed control
• Solid state relay output stages
• Lighting dimmer circuits

Triacs Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package type matches TO-220-3 Non-Isolated Tab requirements. Ensure storage conditions comply with Littelfuse guidelines to maintain junction integrity prior to assembly.

Triacs Selection Notes

Select this component when a 400 V blocking capability and 15 A continuous current handling are required in a through-hole format. Consider the 50 mA gate trigger sensitivity for driver compatibility. Evaluate thermal dissipation needs based on the non-isolated tab construction for heat sinking strategies.

Triacs Part Context

This part belongs to the Teccor series of TRIACs manufactured by Littelfuse Inc. It represents a standard thyristor solution within the broader portfolio of power control devices, offering reliable performance for medium-power AC switching tasks in consumer and industrial electronics.

Triacs Replacement Considerations

Cross-reference with other 400V 15A TRIACs in TO-220 packages if availability is constrained. Verify pinout compatibility and thermal resistance values before substituting with equivalent parts from different manufacturers.
