BTA410X-800ET,127

Triacs Overview

The BTA410X-800ET,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 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 110 A. It features a rated repetitive off-state voltage of 800 V and a maximum junction temperature capability of +150 °C. Key electrical parameters include a gate trigger current of 50 mA across quadrants Q1, Q2, and Q3, and a holding current maximum of 60 mA.

Triacs Feature Summary

• High commutation performance enabling full RMS current commutation at maximum rated junction temperature without snubber assistance
• Planar passivated construction optimized for environments with high static and dynamic dV/dt and dI/dt
• Three-quadrant operation providing balanced gate sensitivity for interfacing with low power drivers including microcontrollers

Triacs Applications

• Industrial motor control systems requiring high junction operating temperature capability
• Solid state relays operating under high commutation stress conditions
• Lighting control circuits interfacing with microcontroller-based logic drivers

Triacs Procurement Notes

Verify the specific suffix ET against official datasheets to confirm the TO-220F full pack package variant. Confirm RoHS compliance status and lead-free plating specifications directly from the manufacturer's documentation before procurement. Ensure the ordering part number matches the required industrial qualification level.

Triacs Selection Notes

Select this component when circuit designs demand high dV/dt immunity and reliable commutation at elevated temperatures up to 150 °C. The TO-220F package provides necessary thermal management for 10 A RMS applications. Verify that the 50 mA gate trigger current aligns with the driving circuit's output capabilities for all three quadrants.

Triacs Part Context

This triac belongs to the BTA410 series within the WeEn Semiconductors thyristor portfolio. It shares core electrical ratings with variants like the BTA410X-800BT but differs in packaging and specific commutation characteristics. The ET suffix denotes the TO-220F insulated package configuration intended for general industrial use.

Triacs Replacement Considerations

The BTA410X-800BT serves as a comparable alternative within the same family. Both share identical 10 A and 800 V ratings. However, verify package compatibility and specific dV/dt requirements, as the BT variant utilizes a standard TO-220F package rather than the internally insulated full pack design.
