COMMUTATING SAFE OPERATING AREA (CSOA)

The Commutating Safe Operating Area (CSOA) of Figure

12 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 IFM and peak VDS 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.

Device stresses increase with increasing rate of change of

source current so dIs/dt is specified with a maximum value.

Higher values of dIs/dt require an appropriate derating of

IFM, peak VDS or both. Ultimately dIs/dt is limited primarily

by device, package, and circuit impedances. Maximum

device stress occurs during trr as the diode goes from

conduction to reverse blocking.

VDS(pk) is the peak drain–to–source voltage that the

device must sustain during commutation; IFM is the

maximum forward source-drain diode current just prior to

the onset of commutation.

VR is specified at 80% of V(BR)DSS to ensure that the

CSOA stress is maximized as IS decays from IRM to zero.

RGS should be minimized during commutation. TJ has

only a second order effect on CSOA.

Stray inductances in ON Semiconductor’s test circuit are

assumed to be practical minimums. dVDS/dt in excess of 10

V/ns was attained with dIs/dt of 400 A/µs.
