Description
AI
Power MOS 8™ is a family of high speed, high voltage (500-1200 V) N-channel
switch-mode power transistors with lower EMI characteristics and lower cost
compared to previous generation devices. These MOSFETs / FREDFETs have been
optimized for both hard and soft switching in high frequency, high voltage
applications rated above 500 W.
The Power MOS 8™ series is a result of extensive research into quiet switching.
Input and reverse transfer capacitance values as well as their ratio were set
at specific values to achieve quiet switching with minimal switching loss. The
Power MOS 8™ series of devices are inherently quiet switching, stable when
connected in parallel, very efficient, and lower cost than previous
generations.
Power MOS 7® is a family of low loss, high voltage, N-Channel enhancement
mode power MOSFETS. Both conduction and switching losses are addressed with
Power MOS 7® by significantly lowering RDS(ON)and Qg. Power MOS 7® combines
lower conduction and switching losses along with exceptionally fast switching
speeds.
Power MOS V® can still provide the best trade-off between performance and
cost in some applications. Power MOS V® utilizes a low resistance aluminum
metal gate structure. This allows for faster gate signal propagation than is
possible with conventional polysilicon gate structures. The result is extremely
low internal chip equivalent gate resistances (EGR) that are up to an order of
magnitude lower than competitive devices which enables uniform high speed
switching across the entire chip.
Body Diode Options
MOSFETs and FREDFETs are available in all voltage ratings. A FREDFET is a
MOSFET with a faster recovery intrinsic body diode. This results in improved
reliability in ZVS circuits due to shorter minority carrier lifetime and
increased commutation dv/dt ruggedness. If a fast recovery body diode is not
needed, MOSFET versions are available.
