Preferred Device

Power MOSFET
3 Amps, 20 Volts

N−Channel SO−8, Dual

These miniature surface mount MOSFET s feature ultra low R
and true logic level performance. They are capable of withstanding
high energy in the avalanche and commutation modes and the
drain−to−source diode has a very low reverse recovery time.
MiniMOSt devices are designed for use in low voltage, high speed
switching applications where power efficiency is important. Typical
applications are dc−dc converters, and power management in portable
and battery powered products such as computers, printers, cellular and
cordless phones. They can also be used for low voltage motor controls
in mass storage products such as disk drives and tape drives. The
avalanche energy is specified to eliminate the guesswork in designs
where inductive loads are switched and offer additional safety margin
against unexpected voltage transients.

POWER MOSFET SWITCHING

Switching behavior is most easily modeled and predicted
by recognizing that the power MOSFET is charge
controlled. The lengths of various switching intervals (Dt)
are determined by how fast the FET input capacitance can
be charged by current from the generator.

The published capacitance data is difficult to use for
calculating rise and fall because drain−gate capacitance
varies greatly with applied voltage. Accordingly, gate
charge data is used. In most cases, a satisfactory estimate of
average input current (I

) can be made from a

G(AV)

rudimentary analysis of the drive circuit so that
t = Q/I

G(AV)

During the rise and fall time interval when switching a
resistive load, V
known as the plateau voltage, V

remains virtually constant at a level

GS

. Therefore, rise and fall

SGP

times may be approximated by the following:

= Q2 x RG/(VGG − V

where

RG = the gate drive resistance
and Q

and V

are read from the gate charge curve.

During the turn−on and turn−off delay times, gate current is
not constant. The simplest calculation uses appropriate
values from the capacitance curves in a standard equation for
voltage change in an RC network. The equations are:

calculating t

and is read at a voltage corresponding to the

d(on)

.

d(off)

At high switching speeds, parasitic circuit elements
complicate the analysis. The inductance of the MOSFET
source lead, inside the package and in the circuit wiring
which is common to both the drain and gate current paths,
produces a voltage at the source which reduces the gate drive
current. The voltage is determined by Ldi/dt, but since di/dt
is a function of drain current, the mathematical solution is
complex. The MOSFET output capacitance also
complicates the mathematics. And finally, MOSFETs have
finite internal gate resistance which effectively adds to the
resistance of the driving source, but the internal resistance
is difficult to measure and, consequently, is not specified.

The resistive switching time variation versus gate
resistance (Figure 9) shows how typical switching
performance is affected by the parasitic circuit elements. If
the parasitics were not present, the slope of the curves would
maintain a value of unity regardless of the switching speed.
The circuit used to obtain the data is constructed to minimize
common inductance in the drain and gate circuit loops and
is believed readily achievable with board mounted
components. Most power electronic loads are inductive; the
data in the figure is taken with a resistive load, which
approximates an optimally snubbed inductive load. Power
MOSFETs may be safely operated into an inductive load;
however, snubbing reduces switching losses.

DRAIN−TO−SOURCE DIODE CHARACTERISTICS

The switching characteristics of a MOSFET body diode
are very important in systems using it as a freewheeling or
commutating diode. Of particular interest are the reverse
recovery characteristics which play a major role in
determining switching losses, radiated noise, EMI and RFI.

System switching losses are largely due to the nature of
the body diode itself. The body diode is a minority carrier
device, therefore it has a finite reverse recovery time, t
to the storage of minority carrier charge, Q

, as shown in

RR

, due

rr

the typical reverse recovery wave form of Figure 15. It is this
stored charge that, when cleared from the diode, passes
through a potential and defines an energy loss. Obviously,
repeatedly forcing the diode through reverse recovery
further increases switching losses. Therefore, one would
like a diode with short t

and low QRR specifications to

rr

minimize these losses.

The abruptness of diode reverse recovery effects the
amount of radiated noise, voltage spikes, and current
ringing. The mechanisms at work are finite irremovable
circuit parasitic inductances and capacitances acted upon by

However, the positive di/dt during t

is an uncontrollable

diode characteristic and is usually the culprit that induces
current ringing. Therefore, when comparing diodes, the
ratio of t

serves as a good indicator of recovery

b/ta

abruptness and thus gives a comparative estimate of
probable noise generated. A ratio of 1 is considered ideal and
values less than 0.5 are considered snappy.

Compared to ON Semiconductor standard cell density
low voltage MOSFETs, high cell density MOSFET diodes
are faster (shorter t

), have less stored charge and a softer

rr

reverse recovery characteristic. The softness advantage of
the high cell density diode means they can be forced through
reverse recovery at a higher di/dt than a standard cell
MOSFET diode without increasing the current ringing or the
noise generated. In addition, power dissipation incurred
from switching the diode will be less due to the shorter
recovery time and lower switching losses.

SAFE OPERATING AREA

The Forward Biased Safe Operating Area curves define
the maximum simultaneous drain−to−source voltage and
drain current that a transistor can handle safely when it is
forward biased. Curves are based upon maximum peak
junction temperature and a case temperature (T

) of 25°C.

C

Peak repetitive pulsed power limits are determined by using
the thermal response data in conjunction with the procedures
discussed in AN569, “Transient Thermal Resistance −
General Data and Its Use.”

Switching between the off−state and the on−state may
traverse any load line provided neither rated peak current

practice is to rate in terms of energy, avalanche energy

non−linearly with an increase of peak current in avalanche
