SWITCHMODE™ Power
Dual Schottky Rectifier
. . . using Schottky Barrier technology with a platinum barrier metal. This
state–of–the–art device is designed for use in high frequency switching power
supplies and converters with up to 48 volt outputs. They block up to 200 volts
and offer improved Schottky performance at frequencies from 250 kHz to
5.0 MHz.
