IXYS Announces 200V Ultra-Junction X3-Class Power MOSFETs with Fast Body Diodes and Lowest On-Resistances

Leiden, Netherlands and Milpitas, CA. December 12, 2017 – IXYS Corporation (NASDAQ: IXYS), a global manufacturer of power semiconductors and integrated circuits (ICs) for energy efficiency, power management, transportation, medical, and motor control applications, today announced a new power semiconductor product line: 200V Ultra-Junction X3-Class HiPerFET™ Power MOSFETs. The current ratings range from 36A to 300A; a broad selection of devices are available in a number of international standard packages.

Fabricated using a charge compensation principle and IXYS’ own process technology, these new MOSFETs exhibit the lowest on-state resistances in the industry (3.5 milliohms in the SOT-227 package and 4 milliohms in the TO-264, for example). Along with gate charges as low as 21 nanocoulombs, these devices enable highest power densities and energy efficiencies in a wide variety of high-speed power conversion applications.

The fast body diodes of the devices are optimized and have low reverse recovery charge and time, thereby suppressing transients and enabling low-noise, high-efficiency power switching. Their low reverse recovery charge and time also boost efficiencies. In addition, these new MOSFETs are avalanche capable and exhibit a superior dv/dt performance (up to 20V/ns).

Targeted applications include synchronous rectification, battery chargers for light electric vehicles (LEVs), motor control (48V-110V systems), DC-DC converters, uninterruptible power supplies, electric forklifts, inverters, power solid state relays, and Class-D audio amplifiers.

The new 250V X3-Class Power MOSFETs with HiPerFET™ body diodes are available in the following international standard size packages: TO-3P, TO-220 (overmolded or standard), TO-247, PLUS247, TO-252, TO-263, TO-264, TO-268HV, SOT-227. Some example part numbers include IXFP36N20X3, IXFA72N20X3, IXFH90N20X3 and IXFN300N20X3, with current ratings of 36A, 72A, 90A and 300A, respectively.
