ACTT10X-800CTNQ

Overview

The ACTT10X-800CTNQ is a planar passivated high commutation three-quadrant triac manufactured by WeEn Semiconductors. It is housed in a TO-220F (SOT186A) full pack plastic package designed for through-hole mounting. The device features an RMS on-state current of 10 A and a rated repetitive peak off-state voltage of 800 V. It supports a non-repetitive peak on-state current of 99 A with a maximum on-state voltage of 1.3 V. The component operates within a junction temperature range up to 150 °C and includes self-protective clamping capabilities against low and high energy transients.

Feature Summary

• High commutation capability allowing full RMS current commutation at maximum rated junction temperature without snubber assistance
• Self-protective clamping capabilities against low and high energy transients
• Planar passivated construction for enhanced reliability in circuits with high static and dynamic dV/dt and dI/dt

Applications

• AC power switching applications requiring high junction operating temperature capability
• Industrial circuits subject to high transient voltages and currents
• Power control systems where snubber-less operation is preferred

Procurement Notes

Verify the specific suffix CTNQ against official manufacturer documentation to confirm marking, packaging, and compliance details. Ensure the ordering part number matches the required tape and reel configuration. Cross-reference the 12NC code for accurate supply chain tracking. Confirm RoHS and lead-free status with the latest datasheet before procurement.

Selection Notes

Select this component when an 800 V blocking voltage and 10 A continuous current rating are required in a TO-220F package. Consider the 150 °C maximum junction temperature for high-thermal environments. Verify gate trigger requirements against the driving circuit capabilities. Compare transient immunity specifications with alternative series if extreme dV/dt conditions are present.

Part Context

This triac belongs to the ACTT series from WeEn Semiconductors, characterized by high commutation performance and robust transient protection. It is part of a family of thyristors designed for industrial power applications. The TO-220F package provides efficient thermal dissipation compared to smaller surface-mount alternatives, supporting higher current densities in through-hole designs.

Replacement Considerations

Check for direct substitutes such as the BTA206X-800CT or other ACTT series variants with matching current ratings. Verify pinout compatibility and thermal resistance values. Ensure replacement parts meet the same 150 °C junction temperature requirement and offer equivalent transient clamping performance.
