1/5 STTH806Dti october 2003 - ed: 2a tandem 600v hyperfast boost diode ? 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 di f /dt. description n especially suited as boost diode in continuous mode power factor correctors and hard switching conditions n designed for high di/dt operation. hyperfast recovery current to compete with sic devices. allows downsizing of mosfet and heatsinks n internal ceramic insulated devices with equal thermal conditions for both 300v diodes n insulation (2500v rms ) allows placement on same heatsink as mosfet and flexible heatsinking on common or separate heatsink n static and dynamic equilibrium of internal diodes are warranted by design n package capacitance: c=7pf features and benefits symbol parameter value unit v rrm repetitive peak reverse voltage 600 v i f(rms) rms forward current 14 a i fsm surge non repetitive forward current tp = 10 ms sinusoidal 80 a ipeak peak current waveform d = 0.15 tc = 130c 17 a t stg storage temperature range -65 +150 c tj maximum operating junction temperature + 150 c absolute ratings (limiting values) i f(av) 8a v rrm 600 v tj (max) 150 c v f (max) 2.4 v i rm (typ.) 4 a t rr (typ.) 13 ns major products characteristics 1 2 12 insulated to-220ab
