TMOS Single P-Channel
Field Effect Transistors
WaveFET
devices are an advanced series of power MOSFETs
which utilize Motorola’s High Cell Density HDTMOS process. These
miniature surface mount MOSFETs feature ultra low RDS(on) and true
logic level performance. They are capable of withstanding high energy in
the avalanche and commutation modes and the drain–to–source diode
has a very low reverse recovery time. WaveFET
devices are designed
for use in low voltage, high speed switching applications where power
efficiency is important. Typical applications are dc–dc converters, and
power management in portable and battery powered products such as
computers, printers, cellular and cordless phones. They can also be
used for low voltage motor controls in mass storage products such as
disk drives and tape drives. The avalanche energy is specified to
eliminate the guesswork in designs where inductive loads are switched
and offer additional safety margin against unexpected voltage transients.
