Field Effect Transistors

MiniMOS

™ 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.

MiniMOS 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.
