BTA206X-800ET/L03Q

Triacs Overview

The BTA206X-800ET/L03Q 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 800 V rated repetitive off-state voltage and an 8 A RMS on-state current capability, with a non-repetitive peak on-state current of 60 A. It supports a maximum junction operating temperature of 150 °C and operates within a temperature range of -40 °C to +150 °C. Key electrical parameters include a maximum gate trigger current of 10 mA across quadrants Q1, Q2, and Q3, and a dV/dt rating of 50 V/µs.

Triacs Feature Summary

• High commutation performance balanced with gate sensitivity for interfacing with low power drivers including microcontrollers.
• Planar passivated construction ensures robustness and reliability under industrial conditions.
• Three-quadrant operation provides flexibility in triggering configurations while maintaining stable switching characteristics.

Triacs Applications

• Industrial motor control systems requiring high junction temperature tolerance.
• Lighting applications utilizing low-power microcontroller-based dimming circuits.
• General purpose AC power switching where high commutation capability is required.

Triacs Procurement Notes

Verify the specific suffix L03Q against official WeEn Semiconductors documentation to confirm marking orientation and packaging details. Ensure compatibility with existing thermal management designs given the 150 °C junction limit. Confirm RoHS compliance status via the latest datasheet revision. Cross-reference the 12NC code for accurate ordering. Validate that the TO-220F package dimensions match the target PCB footprint requirements.

Triacs Selection Notes

Select this component when application demands exceed standard triac commutation capabilities or require operation near microcontroller logic levels. The 8 A RMS rating suits moderate power loads, while the 800 V blocking voltage provides adequate margin for standard AC lines. Consider the TO-220F package for superior heat dissipation compared to standard TO-220 variants. Evaluate gate drive strength to ensure reliable triggering within the 10 mA maximum specification across all quadrants.

Triacs Part Context

This part belongs to the BTA206X series of high commutation triacs from WeEn Semiconductors. The 'X' designation typically indicates the TO-220F insulated package variant, distinguishing it from the standard TO-220AB version. The 'ET' suffix denotes the specific electrical characteristics optimized for high commutation and gate sensitivity. This series is engineered for industrial environments demanding high reliability and thermal stability.

Triacs Replacement Considerations

Direct substitutes may include the BTA206-800ET for non-insulated applications or other 8 A/800 V triacs from manufacturers like STMicroelectronics or Littelfuse. Verify pinout compatibility and thermal resistance values before substitution. Ensure replacement parts meet the same 150 °C junction temperature rating and commutation specifications.
