BTA208X-800B,127

Triacs Overview

The BTA208X-800B,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 through-hole mounting. The device supports an RMS on-state current of 8 A and withstands a rated repetitive peak off-state voltage of 800 V. It features a non-repetitive peak on-state current capability of 65 A and a maximum junction temperature of 125 °C. The gate trigger current is specified at a maximum of 50 mA across quadrants Q1, Q2, and Q3.

Triacs Feature Summary

• High commutation performance allowing full rated RMS current commutation at maximum junction temperature without snubber assistance
• Planar passivated construction providing robustness against high static and dynamic dV/dt and high di/dt conditions
• Three quadrant operation with balanced gate sensitivity suitable for interfacing with low power drivers

Triacs Applications

• Motor control circuits requiring high blocking voltage and high commutation capabilities
• Industrial applications involving high static and dynamic dV/dt environments
• Logic IC and microcontroller interfacing in higher noise environments

Triacs Procurement Notes

Verify the specific suffix and ordering details when sourcing this component. Confirm that the TO-220AB package matches your thermal and mechanical requirements. Ensure compliance with industrial qualification standards if operating in demanding environments. Check for RoHS compliance status as per the latest manufacturer documentation before finalizing procurement decisions.

Triacs Selection Notes

Select this triac when circuit designs demand high commutation performance at elevated temperatures without external snubber networks. The 800 V rating suits general industrial AC switching applications. Consider the 50 mA gate trigger current for driver compatibility. Verify that the TO-220AB package fits the available board space and heatsinking constraints for the intended thermal management strategy.

Triacs Part Context

This component belongs to the BTA208 series of planar passivated triacs from WeEn Semiconductors. The series includes variants such as BTA208-800F and BTA208X-800F, which share similar electrical characteristics but may differ in packaging or specific gate sensitivity optimizations. The BTA208X-800B specifically utilizes the TO-220AB form factor within this product line.

Triacs Replacement Considerations

Direct substitutes include other BTA208 series parts like BTA208-800F or BTA208X-800F, provided the package and electrical ratings align. Cross-reference datasheets for exact dV/dt and gate trigger specifications to ensure functional equivalence in high-noise or high-commutation scenarios.
