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

Data and Its Use” provides detailed instructions.
MAXIMUM DC VOLTAGE CONSIDERATIONS
The maximum drain–to–source voltage that can be contin-
uously applied across the MLP1N06CL when it is in current
limit is a function of the power that must be dissipated. This
power is determined by the maximum current limit at maxi-
mum rated operating temperature (1.8 A at 150°C) and not
the RDS(on). The maximum voltage can be calculated by the
following equation:
Vsupply
=
(150 – TA)
ID(lim) (R_θJC + R_θCA)
where the value of R_θCA is determined by the heatsink that is
being used in the application.
DUTY CYCLE OPERATION
When operating in the duty cycle mode, the maximum
drain voltage can be increased. The maximum operating
temperature is related to the duty cycle (DC) by the following
equation:
TC = (VDS x ID x DC x R_θCA) + TA
The maximum value of VDS applied when operating in a
duty cycle mode can be approximated by:
VDS
=
150 – TC
ID(lim) x DC x R_θJC
