MLD2N06CL
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 maximum junction temperature of 150°C. Limitations
for repetitive pulses at various case temperatures can be
determined by using the thermal response curves.
ON Semiconductor Application Note, AN569, “Transient
Thermal Resistance − General Data and Its Use” provides
detailed instructions.
MAXIMUM DC VOLTAGE CONSIDERATIONS
The maximum drain−to−source voltage that can be
continuously applied across the MLD2N06CL 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 maximum 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) (RqJC + RqCA)
where the value of RqCA 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 RqCA) + TA
The maximum value of VDS applied when operating in a
duty cycle mode can be approximated by:
VDS =
150 − TC
