MLD2N06CL
Preferred Device
SMARTDISCRETESt MOSFET
2 Amp, 62 Volts, Logic Level
N−Channel DPAK
The MLD2N06CL is designed for applications that require a rugged
power switching device with short circuit protection that can be
directly interfaced to a microcontrol unit (MCU). Ideal applications
include automotive fuel injector driver, incandescent lamp driver or
other applications where a high in−rush current or a shorted load
condition could occur.
This Logic Level Power MOSFET features current limiting for
short circuit protection, integrated Gate−Source clamping for ESD
protection and integral Gate−Drain clamping for over−voltage
protection and SENSEFETt technology for low on−resistance. No
additional gate series resistance is required when interfacing to the
output of a MCU, but a 40 kW gate pulldown resistor is recommended
to avoid a floating gate condition.
The internal Gate−Source and Gate−Drain clamps allow the device
to be applied without use of external transient suppression
components. The Gate−Source clamp protects the MOSFET input
from electrostatic voltage stress up to 2.0 kV. The Gate−Drain clamp
protects the MOSFET drain from the avalanche stress that occurs with
inductive loads. Their unique design provides voltage clamping that is
essentially independent of operating temperature.

MLD2N06CL
THE SMARTDISCRETES CONCEPT
SHORT CIRCUIT PROTECTION AND THE EFFECT OF
TEMPERATURE
From a standard power MOSFET process, several active
and passive elements can be obtained that provide on−chip
protection to the basic power device. Such elements require
only a small increase in silicon area and/or the addition of one
masking layer to the process. The resulting device exhibits
significant improvements in ruggedness and reliability as
well as system cost reduction. The SMARTDISCRETES
device functions can now provide an economical alternative
to smart power ICs for power applications requiring low
on−resistance, high voltage and high current.
These devices are designed for applications that require a
rugged power switching device with short circuit protection
that can be directly interfaced to a microcontroller unit
(MCU). Ideal applications include automotive fuel injector
driver, incandescent lamp driver or other applications where
a high in−rush current or a shorted load condition could occur.
The on−chip circuitry of the MLD2N06CL offers an
integrated means of protecting the MOSFET component
from high in−rush current or a shorted load. As shown in the
schematic diagram, the current limiting feature is provided
by an NPN transistor and integral resistors R1 and R2. R2
senses the current through the MOSFET and forward biases
the NPN transistor’s base as the current increases. As the
NPN turns on, it begins to pull gate drive current through R1,
dropping the gate drive voltage across it, and thus lowering
the voltage across the gate−to−source of the power
MOSFET and limiting the current. The current limit is
temperature dependent as shown in Figure 3, and decreases
from about 2.3 amps at 25°C to about 1.3 A at 150°C.
Since the MLD2N06CL continues to conduct current and
dissipate power during a shorted load condition, it is
important to provide sufficient heatsinking to limit the
device junction temperature to a maximum of 150°C.
The metal current sense resistor R2 adds about 0.4 ohms
to the power MOSFET’s on−resistance, but the effect of
temperature on the combination is less than on a standard
MOSFET due to the lower temperature coefficient of R2.
The on−resistance variation with temperature for gate
voltages of 4 and 5 V is shown in Figure 5.
Back−to−back polysilicon diodes between gate and
source provide ESD protection to greater than 2 kV, HBM.
This on−chip protection feature eliminates the need for an
external Zener diode for systems with potentially heavy line
transients.
OPERATION IN THE CURRENT LIMIT MODE
The amount of time that an unprotected device can
withstand the current stress resulting from a shorted load
before its maximum junction temperature is exceeded is
dependent upon a number of factors that include the amount
of heatsinking that is provided, the size or rating of the
device, its initial junction temperature, and the supply
voltage. Without some form of current limiting, a shorted
load can raise a device’s junction temperature beyond the
maximum rated operating temperature in only a few
milliseconds.
Even with no heatsink, the MLD2N06CL can withstand
a shorted load powered by an automotive battery (10 to 14
V) for almost a second if its initial operating temperature is
under 100°C. For longer periods of operation in the
current−limited mode, device heatsinking can extend
operation from several seconds to indefinitely depending on
the amount of heatsinking provided.

FORWARD BIASED SAFE OPERATING AREA
(1.8 A at 150°C) and not the RDS(on). The maximum
voltage can be calculated by the following equation:
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.

where the value of RqCA is determined by the heatsink that

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
MAXIMUM DC VOLTAGE CONSIDERATIONS
The maximum value of VDS applied when operating in a
duty cycle mode can be approximated by:
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

ACTIVE CLAMPING
MLD2N06CL, the integrated gate−to−source voltage
elements provide greater than 2.0 kV electrostatic voltage
protection.
The avalanche voltage of the gate−to−drain voltage clamp
is set less than that of the power MOSFET device. As soon
as the drain−to−source voltage exceeds this avalanche
voltage, the resulting gate−to−drain Zener current builds a
gate voltage across the gate−to−source impedance, turning
on the power device which then conducts the current. Since
virtually all of the current is carried by the power device, the
gate−to−drain voltage clamp element may be small in size.
This technique of establishing a temperature compensated
drain−to−source sustaining voltage (Figure 7) effectively
removes the possibility of drain−to−source avalanche in the
power device.
The gate−to−drain voltage clamp technique is particularly
useful for snubbing loads where the inductive energy would
otherwise avalanche the power device. An improvement in
ruggedness of at least four times has been observed when
inductive energy is dissipated in the gate−to−drain clamped
conduction mode rather than in the more stressful
gate−to−source avalanche mode.
SMARTDISCRETES technology can provide on−chip
realization of the popular gate−to−source and gate−to−drain
Zener diode clamp elements. Until recently, such features
have been implemented only with discrete components
which consume board space and add system cost. The
SMARTDISCRETES technology approach economically
melds these features and the power chip with only a slight
increase in chip area.
In practice, back−to−back diode elements are formed in a
polysilicon region monolithicly integrated with, but
electrically isolated from, the main device structure. Each
back−to−back diode element provides a temperature
compensated voltage element of about 7.2 V. As the
polysilicon region is formed on top of silicon dioxide, the
diode elements are free from direct interaction with the
conduction regions of the power device, thus eliminating
parasitic electrical effects while maintaining excellent
thermal coupling.
To achieve high gate−to−drain clamp voltages, several
voltage elements are strung together; the MLD2N06CL uses
8 such elements. Customarily, two voltage elements are used
to provide a 14.4 volt gate−to−source voltage clamp. For the
TYPICAL APPLICATIONS: INJECTOR DRIVER, SOLENOIDS, LAMPS, RELAY COILS
The MLD2N06CL has been designed to allow direct
interface to the output of a microcontrol unit to control an
isolated load. No additional series gate resistance is required,
but a 40 kW gate pulldown resistor is recommended to avoid
a floating gate condition in the event of an MCU failure. The
internal clamps allow the device to be used without any
external transistent suppressing components.
