Toshiba Debuts Next-Gen Low Voltage MOSFETs

March 16, 2015


40V U-MOS IX-H Delivers Industry-Leading Low RDS(ON)


CHAROLOTTE, N.C., — Toshiba America Electronic Components, Inc. (TAEC)*, a committed leader that collaborates with technology companies to create breakthrough designs, today announced the launch of its 40V power MOSFET U-MOS IX-H series. This family of low-voltage, ultra-efficient trench MOSFETs is based on Toshiba's next generation U-MOS IX-H semiconductor process.

The U-MOS IX-H process re alizes the lowest ON-resistance in the industry, compared to Toshiba's conventional U-MOS VI-H series1. The new MOSFETs also realize a low Qoss2 , for increased efficiency in switching-mode power supplies, including servers and telecom base stations, DC-DC converters, synchronous rectification and other power management circuitry where low-power operation, high-speed switching and minimum PCB real estate are needed. Initially available in a 40V version, the UMOS IX-H series will be extended in the coming months with devices offering ratings of 30V to 60V.

The first device in the series – a 40V version - has a typical RDS(ON) of only 0.7mΩ (max 0.85mΩ) and a typical output capacitance (Coss) of 1930pF. Rated for 40V, the TPHR8504PL is supplied in an ultra-miniature SOP-Advance package measuring just 5mm x 6mm. A current rating of 150A contributes to reliability.

"Better balance between output charge and RDS(ON) leads to increased efficiency," noted Hiroshi Takei, senior business development manager for TAEC. "As a result, our new MOSFETs can help designers to reduce both power consumption and equipment size."
