BTA312-600CT,127

Triacs Overview

The BTA312-600CT,127 is a three-quadrant high commutation triac manufactured by WeEn Semiconductors. It features a rated repetitive off-state voltage of 600 V and an RMS on-state current capability of 12 A. The device supports a non-repetitive peak on-state current of 100 A and operates with a maximum junction temperature of 150 °C. Key electrical parameters include a gate trigger voltage of 800 mV and a gate trigger current of 35 mA across quadrants Q1, Q2, and Q3. It utilizes a TO-263 (D2PAK) surface-mount package.

Triacs Feature Summary

• High commutation capability allowing full RMS current commutation at maximum rated junction temperature without snubber assistance
• Three-quadrant sensitivity ensuring reliable triggering in all gate signal polarities
• Planar passivated construction designed for high static and dynamic dV/dt and dI/dt environments

Triacs Applications

• AC motor speed control applications requiring high dI/dt performance
• Lighting dimmer circuits utilizing surface-mount assembly
• Industrial control systems operating at elevated junction temperatures

Triacs Procurement Notes

Verify the specific ordering suffix to confirm the tape and reel packaging configuration. Ensure the selected variant matches the required surface-mount footprint and thermal management requirements for the target application environment. Cross-reference the manufacturer's latest datasheet for updated qualification status and compliance documentation before finalizing component selection.

Triacs Selection Notes

Select this component when high commutation reliability is critical for AC load switching. The D2PAK package facilitates automated surface-mount assembly while providing adequate thermal dissipation for 12 A continuous operation. Consider the 150 °C junction temperature rating for designs requiring robust thermal headroom in enclosed or high-ambient environments.
