pd -2.459 rev. b 01/99 ? reduced rfi and emi ? reduced snubbing ? extensive characterization of recovery parameters features description hexfred tm 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 hexfred tm HFA70NC60CSM absolute maximum ratings (per leg) smd-61-8 note: ? limited by junction temperature ? l = 100h, duty cycle limited by max t j thermal - mechanical characteristics v r = 600v v f (typ.) ? = 1.2v i f(av) = 70a q rr (typ.) = 210nc i rrm (typ.) = 6a t rr (typ.) = 30ns di (rec)m /dt (typ.) ? = 180a/s ? 125c w parameter max. units v r cathode-to-anode voltage 600 v i f @ t c = 25c continuous forward current 56 i f @ t c = 100c continuous forward current 27 a i fsm single pulse forward current ? 200 e as non-repetitive avalanche energy ? 220 j p d @ t c = 25c maximum power dissipation 150 p d @ t c = 100c maximum power dissipation 59 t j operating junction and t stg storage temperature range soldering temperature, for 10 sec. 300 (0.063 in.
