FORWARD BIASED SAFE OPERATING AREA
The FBSOA curves define the maximum draintosource
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 ambient temperature of
25°C and a maximum junction temperature of 150°C.
Limitations for repetitive pulses at various ambient
temperatures can be determined by using the thermal
response curves. ON Semiconductor Application Note,
AN569, “Transient Thermal ResistanceGeneral Data and
Its Use” provides detailed instructions.
SWITCHING SAFE OPERATING AREA
The switching safe operating area (SOA) 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, BVDSS. The switching
SOA is applicable for both turnon and turnoff of the
devices for switching times less than one microsecond.
