IXYS has announced the expansion of the 'Dual Thyristor –Triac' technology platform (DT-Triac) from 1,600V up to 1,800V. The DT-Triac technology distinguishes itself as a high performance solution in Triac related applications with superior ruggedness and better dV/dt and di/dt ratings when compared to state of the art triacs. The DT-Triac products use IXYS’ advanced planar thyristors that extend the current and voltage ratings of Triacs beyond the limitations of current triac technology.

Presently IXYS has offered a wide portfolio of 1,200V DT-Triac in several standard housings including the established ISOPLUS technology for in-package isolation. With these recent products the range is extended to 1,600V Triacs.

The first products are two 60A discrete devices in the TO-247 case style, the CMA60MT1600NHB with the standard TO-247 case and the CMA60MT1600NHR providing the same outline and pin compatibility but with a ceramic backside for a high performance isolation.

On the module side IXYS provides two power classes in two different packages. MCMA650MT1800NKD is a high reliable 1,800V Triac in the common housing Y1 (50mm). Next to this powerful AC-Controller, IXYS shows a special 700A phase-leg in its latest ComPack package outline. The MCMA700P1600NCA connected in an anti-parallel mode creates a 1,600A Power-Triac that combines all the advantages for a Triac application with the capability and high performance of singles thyristors in this current class.

“The IXYS DT-Triac is designed for line frequency applications and three quadrant operation, namely quadrants I to III,” said Dr. Elmar Wisotzki, Director of Technology, IXYS Germany. “With the unique advantages of the DT-Triac solutions IXYS is continuing to explore new ideas to enhance bipolar technology for power semiconductors to new dimensions.”

The target applications for these devices are solid state relays, soft start AC motor control, DC motor control, HVAC systems, UPS, AC power control, input power control for SMPSs, lighting and off line battery chargers.
