BTA312-800CT/DG,12

Triacs Overview

The BTA312-800CT/DG,12 is a planar passivated high commutation three quadrant triac manufactured by WeEn Semiconductors. It is housed in a TO263 plastic package and designed for circuits requiring high static and dynamic dV/dt and dI/dt capabilities. The device supports an RMS current of 12 A with a peak non-repetitive surge current of 100 A. It features a rated repetitive peak off-state voltage of 800 V and a maximum junction temperature of 150 °C. This component allows full RMS current commutation at the maximum rated junction temperature without snubber assistance.

Triacs Feature Summary

• High commutation capability enabling operation without snubber circuits
• Logic level gate sensitivity for interfacing with low power drivers
• Planar passivated construction for robust performance under high dV/dt conditions

Triacs Applications

• Industrial motor control systems
• High-temperature power switching applications
• Solid state relays requiring high commutation ratings

Triacs Procurement Notes

Verify the specific suffix DG against official manufacturer documentation to confirm pinout and isolation characteristics. Ensure the ordering part number matches the exact package variant required for your PCB layout. Cross-reference the 12NC code with current production status to avoid obsolete components.

Triacs Selection Notes

Select this component when high junction temperature tolerance up to 150 °C is required. It is suitable for designs needing snubberless operation in high dV/dt environments. Compare gate trigger currents across quadrants if microcontroller interface sensitivity is critical for the application design.
