BTA312-600C,127

Triacs Overview

The BTA312-600C,127 is a planar passivated high commutation three-quadrant triac manufactured by WeEn Semiconductors. It is housed in a TO-220AB (SOT78) plastic package designed for through-hole mounting. The device features a rated repetitive off-state voltage of 600 V and an on-state RMS current of 12 A. It supports a non-repetitive peak on-state current of 100 A. Key electrical parameters include a maximum on-state voltage of 1.5 V, a holding current maximum of 50 mA, and a gate trigger current of 35 mA across quadrants Q1, Q2, and Q3. The component operates with a maximum junction temperature of 125 °C and exhibits 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 circuits.
• Planar passivated construction provides robustness against high static and dynamic dV/dt and high dI/dt conditions.
• Three-quadrant triggering ensures reliable gate activation in Q1, Q2, and Q3 operating modes.

Triacs Applications

• Industrial motor control systems requiring high commutation reliability.
• Solid-state relays operating under high dV/dt stress conditions.
• General purpose AC power switching applications.

Triacs Selection Notes

Select this component when circuit designs demand high commutation performance to eliminate external snubber networks. The TO-220AB package facilitates standard through-hole PCB assembly. Ensure the application voltage does not exceed the 600 V DRM rating and that thermal management supports the 125 °C maximum junction temperature limit during continuous 12 A operation.

Triacs Part Context

This part belongs to the BTA312 series of high commutation triacs from WeEn Semiconductors. The series includes variants with different voltage ratings such as the BTA312-800C and alternative package options like the surface-mountable BTA312B-600C in a D2PAK case. The BTA312-600C specifically targets industrial environments where robust switching and high dV/dt immunity are critical requirements.

Triacs Replacement Considerations

Direct substitutes within the same family include the BTA312-800C for higher voltage tolerance or the BTA312X-600C for a TO-220F package. Surface-mount equivalents include the BTA312B-600C. Verify pinout compatibility and thermal resistance differences when replacing with these variants.
