New 60V – 120V family of MOSFETs for synchronous rectification

Use of Toshiba’s eighth generation N-channel U-MOSVIII-H process has allowed the company to reduce the RDS(ON) * Ciss ‘figure of merit’ compared to previous generations by up to 42%. This improves overall efficiency by driving down both conduction and drive losses at the same time as significantly improving switching speeds. The new process technology also helps to minimise radiated noise.

Among the first devices to be launched in the new family are the TK100E08N1 and TK100E10N1 in TO-220 packages and the TK100A08N1 and TK100A10N1 in TO-220SIS ‘smart isolation’ package formats. These ‘best-in-class’ devices have VDSS ratings of 80V (TK100E08N1 and TK100A08N1) and 100V (TK100E10N1 and TK100A10N1). Target applications range from AC/DC adaptor and industrial equipment to servers and telecom power designs.

For the TK100*08 MOSFETs typical on resistance (@ VGS = 10V) is rated at 2.6mΩ and typical Ciss is just 9100pF. In the case of the TK100*10 devices, RDS(ON) (@ VGS = 10V) is 2.8mΩ for the TO-220 package and 3.2mΩ for the TO-220SIS package. For both MOSFETs typical Ciss is only 8800pF.

Toshiba’s full range of 80V and 100V MOSFETs based on the U-MOSVIII-H process features 18 devices offering a range of RDS(ON) * Ciss ratings to match the needs of a broad variety of synchronous rectification applications. In the coming months Toshiba will launch a number of additional 60V and 120V devices based on the same technology.
