1/6 stth8r03g/d february 2001 - ed: 1h 300v hyperfast rectifier ? the turboswitch "r" is an ultra high performance diode. this turboswitch family, which drastically cuts losses in associated mosfet when run at high dif/dt, is suited for hf off-line smps and dc/dc converters. description n designed for high frequency applications. n hyperfast recovery competes with gaas devices. n allows size decrease of snubbers and heatsinks. features and benefits symbol parameter value unit v rrm repetitive peak reverse voltage 300 v i f(rms) rms forward current 20 a i f(av) average forward current tc = 140c d = 0.5 8a i fsm surge non repetitive forward current tp = 10 ms sinusoidal 80 a t stg storage temperature range - 65 + 175 c tj maximum operating junction temperature + 175 c absolute ratings (limiting values, per diode) i f(av) 8a v rrm 300 v i rm (typ.) 4a tj (max) 175 c v f (max) 1.3 v trr (max) 30 ns major product characteristics k k a to-220ac STTH8R03D k nc a d 2 pak stth8r03g
