Toshiba 's 80V N-channel silicon MOSFETs are aimed at switching power supplies in industrial equipment in data centres and communication base stations.

Toshiba has added 80V N-channel power MOSFETs to its U-MOS X-H range for switching power supplies in data centres and communication base stations. The range includes the TPH2R408QM in a small outline SOP Advance surface mount package and the TPN19008QM in a TSON Advance package.

The drain-source on resistance (RDSon) in the 80V U-MOS X-H products is approximately 40 per cent lower than that of 80V products in the current generation process U-MOS VIII-H series products. The trade-off between the drain-source On-resistance and the gate charge characteristics has also been improved by optimising the device structure. As a result, the devices have a power dissipation of 210W for both devices.

Compared with TPH4R008NH (U-MOS VIII-H series), the TPH2R408QM has improved its drain-source On-resistance x total gate charge by approximately 15 per cent, drain-source On-resistance x gate switch charge by approximately 10 per cent, and driain-source On-resistance x output charge by approximately 31 per cent. The RDSon of the MOSFETs is 2.43mΩ (max) @VGS=10V for the TPH2R40QM and 19mΩ (max) @VGS=10V for the TPN19008QM.
