| ? reduced rfi and emi ? reduced snubbing ? extensive characterization of recovery parameters ? hermetic ? 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 = 1200v i f(av) = 15a q rr = 370ns hfa35hb120c www.irf.com 1 parameter max. units v r cathode to anode voltage (per leg) 1200 v i f(av) continuous forward current, t c =100c 15 i fsm single pulse forward current, t c = 25c (per leg) 80 p d @t c = 25c maximum power dissipation 63 w t j, t stg operating junction and storage temperature range -55 to +150 c a case style to-254aa (isolated base) anode common anode cathode pd-20371e 2 www.irf.com hfa35hb120c thermal - mechanical characteristics parameter typ. max. units r thjc junction-to-case, single leg conducting ? 2.0 wt weight 9.3 ? g c/w dynamic recovery characteristics (per leg) @ t j = 25c (unless otherwise specified) parameter min. typ. max. units test conditions t rr1 reverse recovery time ? 58 100 ns t j = 25c see fig. t rr2 ? 110 165 t j = 125c 5 i f = 7a i rrm1 peak recovery current ? 5.4 8.1 t j = 25c see fig. i rrm2 ? 7.2 10.8 t j = 125c 6 v r = 200v q rr1 reverse recovery charge ? 185 370 t j = 25c see fig. q rr2 ? 395 590 t j = 125c 7 di f /dt = 200a/s di (rec)m /dt1 peak rate of fall of recovery current ? 255 380 t j = 25c see fig. di (rec)m /dt2 during t b ? 160 240 t j = 125c 8 electrical characteristics (per leg) @ t j = 25c (unless otherwise specified) parameter min. typ. max. units test conditions v br cathode anode breakdown voltage 1200 ? ? v i r = 250a v f forward voltage ? ? 3.1 i f = 7.0a, t j = -55c see fig. 1 ? ? 3.3 v i f = 7.0a ? ? 4.4 i f = 15a ? ? 2.8 i f = 7.0a, t j = 125c i r max reverse leakage current ? ? 10 a v r = v r rated see fig. 2 ? ? 1.0 ma v r = 960v, t j = 125c c t junction capacitance, see fig. 3 ? 10 15 pf v r = 200v l s series inductance ? 8.7 ? nh measured from anode lead to cathode lead, 6mm (0.025 in) from package www.irf.com 3 hfa35hb120c fig. 4 - maximum thermal impedance z thjc characteristics (per leg) fig. 2 - typical reverse current vs. reverse voltage (per leg) fig. 3 - typical junction capacitance vs. reverse voltage (per leg) fig. 1 - typical forward voltage drop vs. instantaneous forward current (per leg) 0.001 0.01 0.1 1 10 100 1000 0 300 600 900 1200 r r reverse voltage - v (v) reverse current - i (a) t = 125c j t = 25c j t = 150c j 1 10 100 1 10 100 1000 reverse voltage - v (v) r t junction capacitance - c (pf) a t = 25c j 0.01 0.1 1 10 0.00001 0.0001 0.001 0.01 0.1 1 notes: 1. duty factor d = t / t 2. peak t = p x z + t 1 2 j dm thjc c p t t dm 1 2 t , rectangular pulse duration (sec) thermal response (z ) 1 thjc 0.01 0.02 0.05 0.10 0.20 d = 0.50 single pulse (thermal response) 0 1.0 2.0 3.0 4.0 5.0 6.0 forward voltage drop - v f (v) 1 10 100 i n s t a n t a n e o u s f o r w a r d c u r r e n t - i f ( a ) tj = -55c tj = 125c tj = 25c 4 www.irf.com hfa35hb120c fig. 7 - typical stored charge vs. di f /dt fig. 8 - typical di (rec)m /dt vs. di f /dt fig. 5 - typical reverse recovery vs. di f /dt fig. 6 - typical recovery current vs. di f /dt 0 30 60 90 120 150 100 1000 trr - (ns) f di /dt - (a/s) i = 14a i = 7a i = 3.5a f f f v = 200v t = 125c t = 25c r j j 1 10 100 100 1000 f di /dt - (a/s) rrm i - (a) i = 14a i = 7a i = 3.5a f f f v = 200v t = 125c t = 25c r j j 10 100 1000 100 1000 f di /dt - (a/s) rr q - (nc) i = 14a i = 7a i = 3.5a f f f v = 200v t = 125c t = 25c r j j 10 100 1000 10000 100 1000 f di /dt - (a/s) di(rec)m/dt - (a/s) v = 200v t = 125c t = 25c r j j i = 7a f i = 14a f i = 3.5a f !
