Motorola TMOS Power MOSFET Transistor Device Data
Medium Power Surface Mount Products
WaveFET devices are an advanced series of power MOSFETs which utilize Motorola’s
latest MOSFET technology process to achieve the lowest possible on–resistance per silicon
area. 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.
