FDB38N30U — N-Channel UniFETTM Ultra FRFETTM MOSFET November 2013 FDB38N30U Features •R DS(on) = N-Channel UniFETTM Ultra FRFETTM MOSFET 300 V, 38 A, 120 mΩ Description UniFETTM MOSFET is Fairchild Semicondu ctor’s hig h voltage MOSFET family based on planar stripe and DMOS techn ology. This MOSFET is tailored to r educe on-state r esistance, and to provide be tter switching performance and higher avalanche energy streng th. UniFET Ultra F RFETTM MOSFET has much superior body diode reverse recovery performance. Its trr is less than 50nsec and the r everse dv/dt immunity is 20V/nsec while normal planar MOSF ETs have over 200 nsec and 4 .5V/nsec respectively.
