Toshiba Develops 40V N-channel Power MOSFETs with Improved Thermal Performance

July 31, 2018

Toshiba Electronic Devices & Storage Corporation

- New packaging provides double-sided cooling for improved heat dissipation

DSOP Advance(WF)

TOKYO—In August, Toshiba Electronic Devices & Storage Corporation (“Toshiba”) will start mass production and shipments of “TPWR7904PB” and “TPW1R104PB”, 40V N-channel power MOSFETs for automotive applications. They are housed in the DSOP Advance(WF) packages that deliver double-sided cooling, low resistance, and small size.

The new products secure high heat dissipation and low On-resistance characteristics by mounting a U-MOS IX-H series chip, a MOSFET with the latest trench structure, into a DSOP Advance(WF) package. Heat generated by conduction loss is effectively dissipated, improving the flexibility of thermal design.

The U-MOS IX-H series also delivers lower switching noise than Toshiba’s previous U-MOS IV series, contributing to lower EMI[1]. The DSOP Advance(WF) package has a wettable flank terminal structure[2].

Applications

  • Electric power steering
  • Load switches
  • Electric pumps

Features

  • Qualified for AEC-Q101, suitable for automotive applications
  • Double-sided cooling package with top plate[3] and drain
  • Improved AOI visibility due to wettable flank structure
  • U-MOS IX-H series featuring low On-resistance and low noise characteristics
