Product News 2023-02
Toshiba Electronic Devices & Storage Corporation ("Toshiba") has expanded the lineup of 150 V N-channel power MOSFETs with new products that adopt the new generation process “U-MOS X-H series.” Products in this series are suitable for the switching power supplies of communication equipment and so forth. They are “TPH1400CQH,” which has a drain-source On-resistance of 14.1 mΩ, and “TPN4800CQH,” which has a drain-source On-resistance of 48 mΩ. Both of them use surface mount packages.
The new products have reduced their drain-source On-resistance compared with the 150 V products using the current generation process U-MOS VIII-H series. In addition, by optimizing the device structure, the products have improved the tradeoff between the drain-source On-resistance and output charge[1], featuring industry-leading[2] low power loss. Moreover, the products have reduced the spike voltage generated between the drain and the source when switching, helping lower the EMI of switching power supplies.
Notes :
[1] Reduced the drain-source On-resistance (typ.) × output charge (typ.), a figure of merit for switching applications.
TPH1400CQH: About 41 % reduction compared to the current product TPH1500CNH (U-MOS VIII-H series)
TPN4800CQH: About 20 % reduction compared to the current product TPN5900CNH (U-MOS VIII-H series)
