| ? reduced rfi and emi ? reduced snubbing ? extensive characterization of recovery parameters ? hermetic ? electrically isolated ? ceramic eyelets 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 = 600v v f = 1.7v q rr = 375nc HFA45HI60C www.irf.com 1 parameter max. units v r cathode to anode voltage (per leg) 600 v i f(av) continuous forward current, t c =100 c 45 * i fsm single pulse forward current, t c = 25c (per leg) 225 p d @ t c = 25c maximum power dissipation 104 w t j, t stg operating junction and storage temperature range -55 to +150 c case style to-259aa (isolated base) anode common anode cathode !
