BTA312G-600CTQ

Triacs Overview

The BTA312G-600CTQ is a planar passivated high commutation three-quadrant triac manufactured by WeEn Semiconductors. It is housed in a TO262 (SOT226A, I2PAK) plastic package and designed for circuits subject to high static and dynamic dV/dt and dI/dt conditions. The device supports an RMS current of 12 A with a non-repetitive peak on-state current of 100 A. It features a rated repetitive peak off-state voltage of 600 V and a maximum junction temperature of 150 °C. Key electrical parameters include a gate trigger current of 35 mA across quadrants Q1, Q2, and Q3, and a critical rate of rise of off-state voltage of 300 V/µs.

Triacs Feature Summary

• High commutation capability allows full RMS current commutation at maximum rated junction temperature without requiring a snubber circuit.
• Planar passivated construction provides robust performance in environments characterized by high static and dynamic dV/dt and dI/dt stress.
• Extended thermal rating enables reliable operation at elevated junction temperatures up to 150 °C.

Triacs Applications

• Industrial motor control systems
• High-power lighting dimmers
• Solid-state relays

Triacs Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm package type and compliance status. Ensure the orderable part number matches the required packing configuration, such as horizontal rail pack or reel formats, as specified in the product data sheet. Cross-reference the 12NC code for accurate chemical content and RoHS qualification details before finalizing procurement.

Triacs Selection Notes

Select this component when high commutation performance is required to eliminate external snubber networks. The 150 °C junction temperature rating makes it suitable for applications demanding higher thermal margins compared to standard 125 °C devices. Ensure the gate drive circuit can supply the specified 35 mA trigger current across all operating quadrants to guarantee reliable switching under load.

Triacs Part Context

This part belongs to the BTA312 series of three-quadrant triacs from WeEn Semiconductors. The 'CT' designation specifically indicates the high commutation variant optimized for high-temperature operation without snubbers. It serves as a surface-mount alternative to through-hole packages like the TO-220AB, offering similar electrical characteristics in a compact D2PAK-style form factor.

Triacs Replacement Considerations

Direct replacements within the same series include BTA312B-600CT for through-hole TO-220 packages or BTA312B-600CT for surface-mount TO-263 packages. Verify that substitute parts maintain the 150 °C junction temperature rating and 35 mA gate trigger current requirements to ensure compatibility with existing high-commutation designs.
