8/21/01 ? reduced rfi and emi reduced snubbing extensive characterization of recovery parameters hermetic ceramic eyelets features description these ultrafast, soft recovery diodes are optimized to reduce losses and emi/rfi in high frequency power conditioning systems. an extensive characterization of the recovery behavior for different values of current, temperature and di/dt simplifies the calculations of losses in the operating conditions. the softness of the recovery eliminates the need for a snubber in most applications. these devices are ideally suited for power converters, motors drives and other applications where switching losses are significant portion of the total losses. ultrafast, soft recovery diode fred v r = 200v i f(av) = 16a t rr = 30ns note: d.c. = 50% rect. wave 1/2 sine wave, 60 hz , p.w. = 8.33 ms HFB16HY20CC www.irf.com 1 parameter max. units v r cathode to anode voltage ( per leg ) 200 v i f(av) continuous forward current, t c = 132c 16 i fsm single pulse forward current, t c = 25c ( per leg ) 130 p d @ t c = 25c maximum power dissipation 84 w t j, t stg operating junction and storage temperature range -55 to +150 c a absolute maximum ratings case style to-257aa (isolated base) anode common anode cathode pd - 94223a
