MTD20P03HDL
Preferred Device
Power MOSFET
20 Amps, 30 Volts, Logic Level
P−Channel DPAK
This Power MOSFET is designed to withstand high energy in the
avalanche and commutation modes. This energy efficient design also
offers a drain−to−source diode with a fast recovery time. Designed for
low voltage, high speed switching applications in power supplies,
converters and PWM motor controls, these devices are particularly
well suited for bridge circuits where diode speed and commutating
safe operating areas are critical and offer additional safety margin
against unexpected voltage transients.
Features
• Avalanche Energy Specified
• Source−to−Drain Diode Recovery Time Comparable to a Discrete
Fast Recovery Diode
• Diode is Characterized for Use in Bridge Circuits
• IDSS and VDS(on) Specified at Elevated Temperature
• Pb−Free Packages are Available

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, trr, due
to the storage of minority carrier charge, QRR, as shown in
the typical reverse recovery wave form of Figure 12. 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 trr and low QRR specifications to
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
high di/dts. The diode’s negative di/dt during ta is directly
controlled by the device clearing the stored charge.
However, the positive di/dt during tb is an uncontrollable
diode characteristic and is usually the culprit that induces
current ringing. Therefore, when comparing diodes, the
ratio of tb/ta serves as a good indicator of recovery
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 trr), have less stored charge and a softer
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.
