Ultra-Efficient, High-Speed, Low Voltage MOSFETS
(Power Electronics Technology Via Acquire Media NewsEdge) Toshiba
America Electronic Components, Inc., (TAEC), announced a new
family of ultra-high-efficiency, high-speed MOSFETs that deliver
significant improvements in trade-off characteristics between low
on resistance (RDS(ON)) and low input capacitance (Ciss). The new
trench MOSFET series will have voltage ratings from 60V to 120V and
will allow designers to reduce the size and improve the efficiency
and performance of secondary synchronous rectification in switch
mode power supplies.
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 percent. 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 minimize 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 voltage ratings of 80V (TK100E08N1
and TK100A08N1) and 100V (TK100E10N1 and TK100A10N1). Target
applications range from AC/DC adapters and industrial equipment to
servers and telecom power designs.
For the TK100*08 MOSFETs, typical RDS(ON) (@ VGS = 10V) is rated
at 2.6m? and typical Ciss is just 9100pF. In the case of the
TK100*10 devices, RDS(ON) (@ VGS = 10V) is 2.8m? for the
TO-220 package and 3.2m? 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.
Samples of these latest additions to the Toshiba MOSFETs lineup
are available now, with mass production beginning to ramp.
