BTA204X-600D,127

Triacs Overview

The BTA204X-600D,127 is a planar passivated high commutation three quadrant triac manufactured by WeEn Semiconductors. It is housed in a SOT186A (TO-220F) "full pack" plastic package designed for through-hole mounting. This Series D device balances commutation performance with gate sensitivity, making it suitable for interfacing with low power drivers and logic ICs, including microcontrollers. Key electrical parameters include a rated repetitive off-state voltage of 600 V, an on-state RMS current of 4 A, and a non-repetitive peak on-state current of 25 A. The maximum junction temperature is +125 °C.

Triacs Feature Summary

• High commutation capability with guaranteed dV/dt ratings for reliable operation in inductive environments
• Three quadrant design optimized for interfacing with low power drivers and logic ICs
• Planar passivated construction ensures robustness and long-term stability

Triacs Applications

• Motor control circuits requiring high static and dynamic dv/dt immunity

Triacs Selection Notes

Select this component when a TO-220F package is required for thermal management alongside logic-level gate drive compatibility. Compare against Series E variants if higher dV/dt immunity is needed, or Series B variants if different gate trigger characteristics are preferred. Ensure the 600 V rating aligns with the peak line voltage plus transients in the target application circuit.

Triacs Part Context

This part belongs to the BTA204X family of three quadrant triacs from WeEn Semiconductors. The family includes variations such as the BTA204X-600B, BTA204X-600E, and BTA204X-800E, which differ primarily in gate trigger currents and dV/dt ratings while maintaining similar current and voltage capabilities. The Series D designation specifically denotes the balance between commutation performance and gate sensitivity for microcontroller interfacing.

Triacs Replacement Considerations

Direct replacements within the same package and specification range include the BTA204X-600B,127 and BTA204X-600E,127. Verify that the gate trigger current and dV/dt ratings of the substitute part meet the original circuit requirements before substitution.
