A New Fast and Rugged 100 V Power MOSFET

A new, rugged 100 V power MOSFET of the OptiMOStrade 2-family is described. By applying compensation principles, a device technology was developed that combines low on-state resistance R
_ON
with outstanding switching properties. The technology also offers a small gate charge Q
_G
and a small gate resistance R
_G
. In addition, the internal body diode, when acting as freewheeling diode, reveals a soft reverse-recovery with a small reverse-recovery charge Q
_RR
. Therefore, the technology is particularly suitable for a variety of applications, including highly efficient DC-DC and AC-DC converters, telecommunication and server topologies, Class-D amplifiers, and motor control
