MOTOROLA Order this document SEMICONDUCTOR TECHNICAL DATA by MMDF2N05ZR2/D Designer's? Data Sheet MMDF2N05ZR2 Medium Power Surface Mount Products Motorola Preferred Device TMOS Dual N-Channel with Monolithic Zener ESD DUAL TMOS POWER MOSFET Protected Gate 2.0 AMPERES 50 VOLTS EZFETs? are an advanced series of power MOSFETs which RDS(on) = 0.300 OHM utilize Motorola’s High Cell Density TMOS process and contain monolithic back–to–back zener diodes. These zener diodes ? provide protection against ESD and unexpected transients. These miniature surface mount MOSFETs feature ultra low RDS(on) and true logic level performance. They are capable of withstanding high D energy in the avalanche and commutation modes and the drain–to–source diode has a very low reverse recovery
