DESCRIPTION
SOT-93
STPS4045CP
TO-247
STPS4045CW
Dual center tap Schottky rectifier suited for
switchmode power supply and high frequency DC
to DC converters.
Packaged either in SOT-93 or TO-247 this device
is intended for use in low voltage, high frequency
inverters, free wheeling and polarity protection
applications.
