Thanks to versions in the SO-8,SOT-
223, DPAK and TO-220 packages,
this technology has now become
well established on a global scale.
This series was followed by
20V/30V products for low-voltage
applications. A transistor in a TO-
220 package allows a switch to be
implemented with a resistance of
less than 6 m
for switching cur-
rents up to 80 A.
Thanks to the continuous develop-
ment of the S-FET technology, tran-
sistors for 24V and 48V applications
are now available with a breakdown
voltage of 100 V (Fig. 1).
New 100-V transistors in
S-FET technology
The new 100-V transistors from In-
fineon Technologies allow forward
100-V MOS transistors in S-FET technology
MOSFETs for the next
millennium
The latest 100-V MOS transis-
tors from Infineon Technologies
are setting new standards for
low-resistance switches:thanks
to their S-FET technology,a 35%
lower R
DS(on)
and up to 30%
higher nominal currents can be
achieved than for competitor
products. The benefits for the
user are a reduced power dissi-
pation and hence the option of
implementing more compact
designs. In addition, the out-
standing ruggedness of these
transistors obviates the need for
protection circuits.
Siemens Semiconductors introduced
the S-FET technology for power
MOSFET transistors in 1996. The
55/60-V transistors which were the
first products of this development
have proved highly successful.

losses to be significantly reduced
and higher currents to be switched
than before. They are also distin-
guished by their great ruggedness
with respect to avalanches and short
circuits. In addition forward resis-
tors can now be implemented in
more compact packages. Thus a
TO-247 package can be replaced by
a TO-220 version with smaller di-
mensions, giving the user greater
flexibility in design and reduced in-
sertion volumes.
The 16-m
switch in the TO-220
package sets new standards in terms
of R

drain current and
avalanche stability. This is clearly il-
lustrated by a comparison of the SPP

(Figs. 2 to 4).
