MOTOROLA Order this document SEMICONDUCTOR TECHNICAL DATA by MMSF3P02Z/D Advance Information MMSF3P02Z Medium Power Surface Mount Products Motorola Preferred Device TMOS Single P-Channel with Monolithic Zener ESD SINGLE TMOS Protected Gate POWER MOSFET EZFETs? are an advanced series of power MOSFETs which utilize 3.0 AMPERES Motorola’s High Cell Density TMOS process and contain monolithic 20 VOLTS back–to–back zener diodes. These zener diodes provide protection RDS(on) = 0.060 OHM against ESD and unexpected transients. These miniature surface ? mount MOSFETs feature ultra low RDS(on) amd 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
