LOW DROP POWER SCHOTTKY RECTIFIER
STPS30L45CG/CR/CT/CW/CFPJanuary 2002- Ed:2B
LOW DROP POWER SCHOTTKY RECTIFIER
Dual center tap schottky rectifiers suited for
Switched Mode Power Supplies and high
frequency DCto DC converters.
Packagedin TO-247, TO-220AB, TO-220FPAB,2 PAK andI2 PAK these devices are intendedfor
use in low voltage, high frequency inverters,
free-wheeling and polarity protection applications.
DESCRIPTION Low forward voltage drop meaning very small
conduction losses Low switching losses allowing high frequency
operation Low thermal resistance Avalanche rated Insulated package: TO-220FPAB
Insulating voltage: 2000V DC
Capacitance= 45pF
