IXYS Introduces New Power MOSFETs in Isolated High Current Package For 55V to 100V Applications
IXYS Corp. announced the release of a new line of High Current Power MOSFETs in versions ranging from 55 to 100V, utilizing IXYS’ unique MOSFET non-planar technology (Trench, suffix T), to provide high efficiency in power management circuits with ultra-low Rds(on) and optimized intrinsic reverse diode.
These IXYS MOSFETs provide for very low conduction and switching losses, and are avalanche rated for hard-switching applications. The principal feature of these products is the joining of IXYS’ Low-Voltage MOSFETs with the reliable, high power handling capability of the discrete ISOPLUS™ i4-Pak™ packaging technology. Silicon current handling has outpaced the ability of most traditional discrete packaging, which typically limits steady state current to 75A. The powerful ISOPLUS i4-Pak™ is used to full effect in this instance by combining its impressive isolation, thermal and power cycling capabilities. In this case, the ISOPLUS i4-Pak™ is configured with 5 heavy-gage leads to provide a high current drain and source paired lead set with joined copper webs and backside heat sinking, all of which conservatively improve the lead current rating to 160A. All IXYS ISOPLUS™ packages are manufactured with internal direct-copper-bonded (DCB) isolation, are UL certified and provide integral backside case isolation.
The IXTF280N055T (rated at 55V, Rds(on) of 0.0028Ωs with an Isolated Rth(jc) of 0.30K/W) and IXTF200N10T (rated at 100V, Rds(on) of 0.0054Ω with an Isolated Rth(jc) of 0.30K/W) are just some examples of High Current ISOPLUS i4-Pak™ Low-Voltage Power MOSFETs.
IXYS’ ISOPLUS™ packages provide high isolation capability (up to 2500V), improve creepage distance and dramatically reduce total thermal resistance. Additionally, the ceramic alumina substrates used also dramatically enhance device reliability due to their impressive thermal and power cycling. Kunze high performance phase change materials can be used to further enhance ISOPLUS package thermal performance.
Low-Voltage Power MOSFETS find homes in many applications. These devices are designed to withstand even the most robust switching conditions commonly required by the automotive market, as well as the industrial sector. Other applications include dc-dc converters, battery chargers, motor drives, inverters, solar panel pass switches, synchronous rectification and others. Additional products and package options are in process, including options for lower and higher voltages.
