STTH506TTI ® Tandem 600V HYPERFAST RECTIFIER MAJOR PRODUCTS CHARACTERISTICS IF(AV) 5A VRRM 600 V (in series) Tj (max) 150 °C VF (max) 2.6 V IRM (typ.) 3.6 A 1 2 3 1 FEATURES AND BENEFITS ESPECIALLY SUITED AS BOOST DIODE IN CONTINUOUS MODE POWER FACTOR CORRECTORS AND HARD SWITCHING CONDITIONS DESIGNED FOR HIGH dIF/dt OPERATION. HYPERFAST RECOVERY CURRENT TO COMPETE WITH SiC DEVICES. ALLOWS DOWNSIZING OF MOSFET AND HEATSINKS INTERNAL CERAMIC INSULATED DEVICES WITH EQUAL THERMAL CONDITIONS FOR BOTH 300V DIODES INSULATION (2500VRMS) ALLOWS PLACEMENT ON SAME HEATSINK AS MOSFET FLEXIBLE HEATSINKING ON COMMON OR SEPARATE HEATSINK. MATCHED DIODES FOR TYPICAL PFC APPLICATION WITHOUT NEED FOR VOLTAGE BALANCE NETWORK Package Capacitance: C=7pF 2 3 Insulated TO-220AB ■ 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. ■ ■ ■ ■ ■ ABSOLUTE RATINGS (limiting values, for both diodes) Symbol Parameter Value Unit VRRM Repetitive peak reverse voltage 600 V IF(RMS) RMS forward current 14 A 60 A -65 +150 °C + 150 °C IFSM Surge non repetitive forward current Tstg Storage temperature range Tj tp = 10 ms sinusoidal Maximum operating junction temperature TM: TURBOSWITCH is a trademark of STMicroelectronics June 2003 - Ed: 1A 1/5 STTH506TTI THERMAL AND POWER DATA Symbol Parameter Rth (j-c) Junction to case thermal resistance Conduction power dissipation for both diodes P Test conditions Value Unit Total 3.0 °C/W IF(AV) = 5 A δ = 0.5 Tc = 100°C 17 W STATIC ELECTRICAL CHARACTERISTICS (for both diodes) Symbol Parameter Tests Conditions IR * Reverse leakage current VR = VRRM Min.
