MOTOROLA Order this document SEMICONDUCTOR TECHNICAL DATA by MMDF2N05ZR2/D Advance Information 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 EZFETs? are an advanced series of power MOSFETs which 50 VOLTS utilize Motorola’s High Cell Density TMOS process and contain RDS(on) = 0.300 OHM 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 t
