Power Field Effect Transistor
TO-247 with Isolated Mounting Hole
N–Channel Enhancement–Mode Silicon Gate
This high voltage MOSFET uses an advanced termination
scheme to provide enhanced voltage–blocking capability without
degrading performance over time. In addition, this advanced TMOS
E–FET is designed to withstand high energy in the avalanche and
commutation modes. The new energy efficient design also offers a
drain–to–source diode with a fast recovery time. Designed for high
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.
• Robust High Voltage Termination
• 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
• Isolated Mounting Hole Reduces Mounting Hardware

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 for-
ward biased. Curves are based upon maximum peak junc-
tion temperature and a case temperature (TC) of 25°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 tra-
verse any load line provided neither rated peak current (IDM)
nor rated voltage (VDSS) is exceeded and the transition time
(tr,tf) do not exceed 10 µs. In addition the total power aver-
aged over a complete switching cycle must not exceed
(TJ(MAX) – TC)/(RθJC).
A Power MOSFET designated E–FET can be safely used
in switching circuits with unclamped inductive loads. For reli-
able operation, the stored energy from circuit inductance dis-
sipated in the transistor while in avalanche must be less than
the rated limit and adjusted for operating conditions differing
from those specified. Although industry practice is to rate in
terms of energy, avalanche energy capability is not a con-
stant. The energy rating decreases non–linearly with an in-
crease of peak current in avalanche and peak junction
temperature.
Although many E–FETs can withstand the stress of drain–
to–source avalanche at currents up to rated pulsed current
(IDM), the energy rating is specified at rated continuous cur-
rent (ID), in accordance with industry custom. The energy rat-
ing must be derated for temperature as shown in the
accompanying graph (Figure 12). Maximum energy at cur-
rents below rated continuous ID can safely be assumed to
equal the values indicated.
