BTA410Y-800CT,127

Triacs Overview

The BTA410Y-800CT,127 is a planar passivated high commutation three quadrant triac manufactured by WeEn Semiconductors. It is housed in a TO-220 plastic package and designed for circuits with high static and dynamic dV/dt and dI/dt. The device supports an RMS current of 10 A and a peak non-repetitive surge current of 100 A. It features a maximum repetitive peak off-state voltage of 800 V and a gate trigger current of 35 mA across quadrants Q1, Q2, and Q3. The component operates at a maximum junction temperature of 150 °C and offers a static dV/dt rating of 500 V/µs.

Triacs Feature Summary

• High commutation capability allows full RMS current commutation at maximum rated junction temperature without snubber assistance.
• Three quadrant operation provides reliable triggering and control across all gate polarities.
• Internally insulated mounting base enables direct heat sink attachment without external insulators.

Triacs Applications

• Industrial motor speed control systems
• Solid state relay designs
• High power lighting dimmers

Triacs Procurement Notes

Verify the complete orderable part number includes the suffix ,127 to ensure correct horizontal rail pack packaging. Confirm RoHS compliance and lead-free plating status against the latest chemical content documentation provided by the manufacturer before finalizing procurement specifications.

Triacs Selection Notes

Select this component when high junction operating temperature capability is required alongside robust commutation performance. Ensure the application circuit can handle the specified 500 V/µt static dV/dt rating. Verify that the 10 A RMS current rating meets the load requirements under worst-case thermal conditions.

Triacs Part Context

This part belongs to the BTA410 series of high commutation triacs from WeEn Semiconductors. It shares core electrical characteristics with variants like the BTA410-800CT but differs in packaging configuration. The CT designation specifically indicates the standard TO-220 plastic package suitable for through-hole mounting.

Triacs Replacement Considerations

Direct substitutes include other BTA410-800CT variants from the same manufacturer family. Cross-brand replacements must match the 10 A RMS current, 800 V blocking voltage, and TO-220 package dimensions while maintaining comparable dV/dt immunity.
