Medium Power Surface Mount Products
Motorola Preferred Device
SINGLE TMOS EZFETs are an advanced series of power MOSFETs which utilize POWER MOSFET Motorola’s High Cell Density TMOS process and contain monolithic 10 AMPERES back–to–back zener diodes. These zener diodes provide protection 30 VOLTS against ESD and unexpected transients. These miniature surface mount RDS(on) = 13 m
MOSFETs feature ultra low RDS(on) and true logic level performance. They are capable of withstanding high energy in the avalanche and commuta- tion modes and the drain–to–source diode has a very low reverse recovery time. EZFET 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
