Q4006F41

Triacs Overview

The Littelfuse Q4006F41 is a standard Triac designed for AC switching and phase control applications. It features a rated repetitive off-state voltage (VDRM) of 400 V and an RMS on-state current (ITRMS) of 6 A. The device operates within a temperature range of -40 °C to +125 °C. It utilizes a TO-202AB through-hole package with three pins, providing a robust solution for low-power triac circuits requiring reliable bidirectional solid-state switching capabilities.

Triacs Feature Summary

• Bidirectional solid-state switch designed for AC power control
• High thermal stability supporting operation up to 125 °C
• Robust flange mount construction for effective heat dissipation
• Standard gate sensitivity suitable for microprocessor drivers

Triacs Applications

• Motor speed control systems
• Temperature modulation circuits
• AC phase control applications
• Lighting dimmer implementations

Triacs Procurement Notes

Verify the specific suffix 'F41' against the manufacturer's official datasheet to confirm the exact packaging configuration and pinout compatibility. Ensure that the procurement channel provides valid traceability documentation. Confirm that the component meets RoHS compliance standards required for your assembly process. Cross-reference the obsolete lifecycle status if sourcing from secondary distributors to guarantee authenticity and storage conditions.

Triacs Selection Notes

Select this component when a 400 V blocking voltage and 6 A continuous current rating are sufficient for the load requirements. Consider the TO-202AB package size constraints during PCB layout planning. Evaluate the thermal management needs based on the 125 °C maximum junction temperature limit. Compare gate trigger characteristics against the driving circuit capabilities to ensure reliable turn-on performance under varying load conditions.

Triacs Part Context

This part belongs to the Qxx06F series of low-power TRIACs from Littelfuse. The series covers ratings up to 1200 V, offering various voltage options within the same current family. The Q4006F41 specifically addresses the 400 V segment, providing a standardized interface for industrial and consumer AC control designs requiring moderate power handling in a traditional leaded package format.
