BTA410X-800CT,127

Triacs Overview

The BTA410X-800CT,127 is a planar passivated high commutation three-quadrant triac manufactured by WeEn Semiconductors. It is housed in a SOT78 (TO-220AB) plastic package designed for circuits experiencing high static and dynamic dV/dt and dI/dt conditions. The device supports an RMS on-state current of 10 A and a non-repetitive peak on-state current of 100 A. It features a rated repetitive off-state voltage of 800 V and a maximum junction temperature of +150 °C. The component operates without snubber assistance at full RMS current under maximum thermal ratings.

Triacs Feature Summary

• Planar passivated construction for enhanced reliability in high-stress environments
• High commutation capability allowing full RMS current switching at maximum junction temperature without snubber circuits
• Insulated tab design suitable for applications requiring high thermal operating temperatures

Triacs Applications

• General purpose AC switching systems
• Industrial motor control circuits
• Lighting dimmer applications

Triacs Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package variant and packing method. Ensure that the requested part number matches the required electrical specifications and compliance standards before finalizing procurement orders.

Triacs Selection Notes

Select this component when circuit designs require robust commutation performance at elevated junction temperatures up to 150 °C. The TO-220AB package facilitates effective heat dissipation for continuous 10 A operation. Confirm compatibility with the system's voltage blocking requirements and gate drive characteristics.

Triacs Part Context

This triac belongs to the BTA410 series from WeEn Semiconductors, which includes variants such as the BTA410X-800BT. While sharing similar electrical ratings, the CT variant utilizes a standard TO-220AB package rather than the insulated TO-220F found in other series members. This distinction affects thermal management strategies and mounting requirements.

Triacs Replacement Considerations

The BTA410X-800BT serves as a functional alternative within the same family, offering identical electrical ratings but featuring an insulated TO-220F package instead of the standard TO-220AB.
