LOW DROP POWER SCHOTTKY RECTIFIER
STPS2030CT/CG/CRJanuary 2003-Ed:2A
LOW DROP POWER SCHOTTKY RECTIFIER
Dual Schottky rectifier suitedfor switch Mode
Power Supply and high frequency DCto DC
converters.
Packagedin TO-220AB,D2 PAK andI2 PAK, this
deviceis intendedfor usein low voltage high
frequency inverters, free wheeling and polarity
protection applications.
DESCRIPTION Very small conduction losses Negligible switching losses Extremely fast switching Low forward voltage dropfor higher efficiency Low thermal resistance
