BTA412Y-800ETQ

Triacs Overview

The BTA412Y-800ETQ is a planar passivated high commutation three-quadrant triac manufactured by WeEn Semiconductors. It is housed in an IITO-220 internally insulated plastic package designed for high junction operating temperature applications. The device balances commutation performance with gate sensitivity, making it suitable for interfacing with low-power drivers including microcontrollers. Key electrical parameters include a rated repetitive peak off-state voltage (VDRM) of 800 V and an on-state RMS current (IT(RMS)) of 12 A. The maximum non-repetitive peak on-state current (ITSM) is 140 A, while the maximum gate trigger current (IGT) across quadrants Q1, Q2, and Q3 is limited to 10 mA.

Triacs Feature Summary

• Features an internally insulated mounting base within the IITO-220 package for enhanced thermal management and safety isolation.
• Designed as a high commutation triac capable of handling high static and dynamic dV/dt and dI/dt conditions.
• Optimized gate sensitivity allows direct interfacing with low-power logic circuits and microcontrollers without additional driver stages.

Triacs Applications

• Industrial motor control systems requiring high commutation capability.
• Solid-state relays and contactor replacement circuits.
• High-temperature power switching applications utilizing microcontroller-based gate drive interfaces.

Triacs Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and marking configurations. Confirm that the requested variant matches the required industrial qualification standards and RoHS compliance status prior to procurement. Cross-reference the 12NC code with the supplier's catalog to avoid substitution errors during acquisition.

Triacs Selection Notes

Select this component when an internally isolated TO-220 style package is required for high-voltage AC switching. Ensure the application demands a 12 A RMS current rating with an 800 V blocking capability. Verify that the gate drive circuit can supply the specified 10 mA trigger current across all three operating quadrants for reliable turn-on.

Triacs Part Context

This part belongs to the BTA412Y series of planar passivated triacs from WeEn Semiconductors. The 'ET' designation typically indicates the specific internal insulation and pin configuration associated with the IITO-220 package family. The 'Q' suffix denotes the bulk or rail packing format used for volume production distribution.

Triacs Replacement Considerations

Direct replacements must match the 800 V voltage rating, 12 A current capacity, and IITO-220 package dimensions. Verify compatibility regarding the maximum junction temperature of 150°C and the specific gate trigger characteristics to ensure seamless integration into existing designs.
