Soft reverse recovery and fast trr can benefit: lower switching losses Better EMI performance MUR460 trr =48ns Reduced 33%! NUR460 trr =36ns IFSM comparison Inrush current The higher IFSM , the more reliability! Outstanding Performance In Application Greener Cleaner More reliable Typical Application- Power Factor Correction The PFC block create a 380V ~ 400V (DC) supply voltage using a high performance axial leaded NUR460 designated D1 in the circuit diagram. Cleaner and Greener (1/2) CH1 (Yellow) CH2 (Blue) voltage across D1; current across D1; waveforms of MUR460 @full load. waveforms of NUR460 @full load. The blip in the highlighted area shows the reverse recovery current of D1 at the moment when the voltage on it rises rapidly. At this point the MOSFET voltage is still significant, and the blip in the diode current appears as an additional turn-transient in the MOSFET. Needless to say, the smaller blip of NUR460 leads to less heat dissipated into MOSFET. Cleaner and Greener (2/2) thermal picture of NUR460@ full load thermal picture of MUR460@ full load Efficiency MUR460 NXP NUR460 0.906 0.9062 0.9064 0.9066 0.9068 0.907 0.9072 0.9074 0.9076 0.9078 The thermal pictures indicate that temperature rises of D1 and MOSFETs S1/S2 are lower when using the NUR460 than using the MUR460. This is in accordance with the efficiency results. NUR460 is well suited for 90W active boost PFC circuit and gives better performance than that of MUR460 in terms of efficiency and temperature rise. The faster trr accounts for its better performance.
