| (R) STTH806TTI TURBOSWITCHTM Tandem 600V ULTRA-FAST BOOST DIODE MAJOR PRODUCTS CHARACTERISTICS IF(AV) VRRM Tj (max) VF (max) IRM (typ.) 8A 600 V (in series) 150 C 2.6 V 4A 1 2 3 1 2 3 Insulated TO-220AB FEATURES AND BENEFITS ESPECIALLY SUITED AS BOOST DIODE IN CONTINUOUS MODE POWER FACTOR CORRECTORS AND HARD SWITCHING CONDITIONS. DESIGNED FOR HIGH DI/DT OPERATION. ULTRA-FAST RECOVERY CURRENT TO COMPETE WITH GaAs DEVICES. SIZE DIMINUTION OF MOSFET AND HEATSINKS ALLOWED. INTERNAL CERAMIC INSULATED PACKAGE ALLOWS FLEXIBLE HEATSINKING ON COMMON OR SEPARATE HEATSINK. MATCHED DIODES FOR TYPICAL PFC APPLICATION WITHOUT VOLTAGE BALANCE NETWORK. INSULATED VERSION: : Insulated voltage = 2500 V(RMS) Capacitance = 7 pF DESCRIPTION The TURBOSWITCH "H" is an ultra high performance diode composed of two 300V dice in series. TURBOSWITCH "H" family drastically cuts losses in the associated MOSFET when run at high dIF/dt.
