BTA06-400CRG

Triacs Overview

The BTA06-400CRG is a standard triac from STMicroelectronics designed for general-purpose AC switching applications. It features a rated RMS on-state current of 6 A and a repetitive peak off-state voltage of 400 V. The device is housed in an insulated TO-220AB package with three pins, suitable for through-hole mounting. Key electrical parameters include a maximum gate trigger current of 50 mA, a holding current of 25 mA, and a non-repetitive surge current rating of 63 A. It operates within a junction temperature range of -40°C to +125°C.

Triacs Feature Summary

• Provides voltage-insulated tab via internal ceramic pad for enhanced safety
• Suitable for phase control operation in light dimmers and motor speed controllers
• Designed for use as ON/OFF function in static relays and heating regulation

Triacs Applications

• Static relays
• Heating regulation systems
• Induction motor starting circuits
• Light dimmers
• Motor speed controllers

Triacs Procurement Notes

Verify the specific voltage rating (400V vs 600V) against the datasheet, as the BTA06 series includes variants like BTA06-600C. Confirm the suffix 'CRG' indicates RoHS compliance and lead-free status. Ensure the TO-220AB package matches the thermal requirements of the application.

Triacs Selection Notes

Select this component for low-power AC switching where a 6A current rating is sufficient. The 400V blocking voltage suits lower voltage AC mains applications. Consider the BTA06-600C variant if higher voltage isolation is required. Verify that the 50mA gate trigger current is compatible with the driving circuit capabilities.

Triacs Part Context

The BTA06 series comprises standard and Snubberless triacs available in through-hole and surface-mount packages. The BTA06-400CRG belongs to the standard version family, distinct from the logic-level or Snubberless variants. This series is widely used for general-purpose AC power control tasks requiring reliable switching performance.

Triacs Replacement Considerations

Direct substitutes include other BTA06 series parts such as BTA06-600C or BTA06-600BWRG, provided the voltage rating meets the circuit requirements. Cross-reference with BTB06 series for surface-mount equivalents if PCB space is constrained.
