BTA316X-800CTQ

Triacs Overview

The BTA316X-800CTQ is a planar passivated high commutation three-quadrant triac manufactured by WeEn Semiconductors. It is housed in an internally insulated SOT78D (IITO-220) plastic package designed for circuits experiencing high static and dynamic dV/dt and high dI/dt. The device supports an RMS current of 16 A with a non-repetitive peak on-state current of 160 A. It features a rated repetitive peak off-state voltage of 800 V and a maximum junction temperature capability of 150 °C, allowing full RMS current commutation without snubber assistance at elevated temperatures.

Triacs Feature Summary

• Internally insulated IITO-220 package provides electrical isolation between the case and terminals.
• High commutation capability enables reliable operation under high static and dynamic dv/dt conditions.
• Snubberless design allows full RMS current commutation at maximum rated junction temperature.

Triacs Applications

• Industrial motor control systems requiring high dv/dt immunity
• Power supplies operating under high di/dt stress
• Equipment demanding high junction temperature reliability

Triacs Procurement Notes

Verify the specific suffix 'CTQ' against the manufacturer's official datasheet to confirm the internal insulation and rail pack configuration. Ensure the ordering part number matches the exact package style required for the application. Cross-reference the 12NC code for accurate supply chain tracking.

Triacs Selection Notes

Select this component when internal case insulation is mandatory for safety or noise reduction. The 800 V rating suits medium-voltage AC applications. Verify that the gate trigger characteristics align with the driving circuit capabilities, particularly regarding the three-quadrant switching requirements.

Triacs Part Context

This part belongs to the BTA316 series of high commutation triacs from WeEn Semiconductors. The 'CT' designation typically indicates the internally insulated IITO-220 package variant, distinguishing it from standard TO-220AB or TO-220F packages within the same electrical family.

Triacs Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with generic IITO-220 16A 800V triacs only if their datasheets explicitly match the internal insulation and commutation specifications.
