To use these curves, it 1s necessary to know the forward current level just before commutation, the circuit commutation di/dt, and the operating junction temperature The reverse re- covery test current waveform for all Motorola fast recovery rectifiers is shown. From stored charge curves versus di/dt, recovery time (tyr) and peak reverse recovery current (IRi(REC}) can be closely approximated using the fotlowing formulas 1/2 OR ter = 141 x} a [23] IRMIREC) = 14t x {aR x dude] We 3-21
