Motorola Preferred Device
SINGLE TMOS POWER MOSFET
Mini MOS devices are an advanced series of power MOSFETs
8.0 AMPERES
which utilize Motorola’s High Cell Density HDTMOS process.
30 VOLTS
These miniature surface mount MOSFETs feature ultra low RDS(on)
RDS(on) = 0.028 OHM
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. Mini MOS 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
