BTA312Y-600C,127

Triacs Overview

The BTA312Y-600C,127 is a planar passivated high commutation three quadrant triac manufactured by WeEn Semiconductors. It is housed in an IITO-220 internally insulated plastic package designed for circuits with high static and dynamic dV/dt and high dI/dt. The device supports a rated repetitive peak off-state voltage (VDRM) of 600 V and an on-state RMS current (IT(RMS)) of 12 A. It features a non-repetitive surge current (ITSM) capability of 100 A. The maximum junction temperature (Tj) is rated at 150 °C, allowing full RMS current commutation without snubber assistance.

Triacs Feature Summary

• High commutation performance enables full RMS current switching at maximum rated junction temperatures without requiring external snubber circuits.
• Internally isolated mounting base provides electrical insulation for the component within the IITO-220 package.
• Planar passivated construction ensures robustness against high static and dynamic dV/dt and high dI/dt conditions.

Triacs Applications

• Industrial motor control systems
• High-power lighting dimmers
• Heating element regulation

Triacs Procurement Notes

Verify the manufacturer marking and part number alignment on the physical component to confirm it originates from WeEn Semiconductors or its authorized supply chain. Ensure the ordering suffix matches the specific packaging requirements. Cross-reference the datasheet specifications against the application's thermal and electrical demands to validate suitability before procurement.

Triacs Selection Notes

Select this component when circuit designs require high commutation capabilities and internal isolation in a TO-220 form factor. The 150 °C maximum junction temperature rating distinguishes it from standard series devices limited to lower thermal thresholds. Verify that the 12 A RMS current rating meets the load requirements and that the 600 V blocking voltage aligns with the system's peak line voltages.

Triacs Part Context

This device belongs to the BTA3xx series of triacs produced by WeEn Semiconductors. It utilizes the IITO-220 package variant, which integrates an electrically isolated mounting tab. This specific 'Series C' designation indicates optimized commutation characteristics compared to other variants in the family, targeting applications demanding reliable switching under harsh electrical stress conditions.

Triacs Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult official replacement guides or contact the manufacturer directly for validated cross-reference data before substituting this component with alternatives from other manufacturers.
