FORWARD BIASED SAFE OPERATING AREA
The FBSOA curves define the maximum drain–to–source
voltage and drain current that a device can safely handle
when it is forward biased, or when it is on, or being turned on.
Because these curves include the limitations of simultaneous
high voltage and high current, up to the rating of the device,
they are especially useful to designers of linear systems. The
curves are based on a case temperature of 25°C and a maxi-
mum junction temperature of 150°C. Limitations for repetitive
pulses at various case temperatures can be determined by
using the thermal response curves. Motorola Application
Note, AN569, “Transient Thermal Resistance–General Data
and Its Use” provides detailed instructions.
SWITCHING SAFE OPERATING AREA
The switching safe operating area (SOA) of Figure 9 is the
boundary that the load line may traverse without incurring
damage to the MOSFET. The fundamental limits are the
peak current, IDM and the breakdown voltage, V(BR)DSS. The
switching SOA shown in Figure 8 is applicable for both turn–
on and turn–off of the devices for switching times less than
one microsecond.
The power averaged over a complete switching cycle must
be less than:
