For any gtven rectifier, recovery time is very circuit depend- ent Typical and maximum recovery time of alt Motorola fast 'RM(RECIF recovery power rectifiers are rated under a fixed set of conditions using Ie = 1.0 A, VQ = 30 V. In order to cover all circuit conditions, curves are given for typical recovered stored charge versus commutation di/dt for various tevels of forward current and for junction temperatures of 25C, 75C, 100C, and 150C. 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 1s shown. From stored charge curves versus di/dt, recovery time (tyr) and peak reverse recovery current (iqn(REC)) can be closely approximated using the following formulas. 1/2 141 (ae. difdt J?
