COMMUTATING SAFE OPERATING AREA (CSOA)
The Commutating Safe Operating Area (CSOA) of
Figure 14 defines the limits of safe operation for
commutated source−drain current versus re−applied drain
voltage when the source−drain diode has undergone
forward bias. The curve shows the limitations of I_FM and
peak V_DS for a given rate of change of source current. It is
applicable when waveforms similar to those of Figure 11 are
present. Full or half−bridge PWM DC motor controllers are
common applications requiring CSOA data.
Stray inductances in Motorola’s test circuit are assumed
to be practical minimums. dV_DS/dt in excess of 10 V/ns was
att1a5iVned with dI_s/dt of 400 A/μs.

t_rr
Device stresses increase with increasing rate of change
of source current so dI_s/dt is specified with a maximum
value. Higher values of dI_s/dt require an appropriate
derating of I_FM, peak V_DS or both. Ultimately dI_s/dt is limited
primarily by device, package, and circuit impedances.
Maximum device stress occurs during t_rr as the diode goes
from conduction to reverse blocking.
V_DS(pk) is the peak drain−to−source voltage that the
device must sustain during commutation; I_FM is the
maximum forward source−drain diode current just prior to
