Description
The SMA6823MP inverter power module (IPM) device
provides a robust, highly-integrated solution for optimally
controlling 3-phase motor power inverter systems and variable
speed control systems used in energy-conserving designs to
drive motors of residential and commercial appliances. These
ICs take 230 VAC input voltage, and 2.5 A (continuous) output
current. They can withstand voltages of up to 500 V (MOSFET
breakdown voltage).
The SMA6820MP power package includes an IC with all of
the necessary power elements (six MOSFETs) and pre-driver
ICs (two) needed to configure the main circuit of an inverter.
This enables the main circuit of the inverter to be configured
with fewer external components than traditional designs.
Applications include residential white goods (home
applications) and commercial appliance motor control:
• Air conditioner fan
• Refrigerator compressor
• Dishwasher pump

High Voltage 3-Phase Motor Driver
WARNING — These devices are designed to be operated at lethal voltages and energy levels. Circuit designs
that embody these components must conform with applicable safety requirements. Precautions must be
taken to prevent accidental contact with power-line potentials. Do not connect grounded test equipment.
The use of an isolation transformer is recommended during circuit development and breadboarding.
Because reliability can be affected adversely by improper storage
environments and handling methods, please observe the following
cautions.
Cautions for Storage
• Ensure that storage conditions comply with the standard
temperature (5°C to 35°C) and the standard relative humidity
(around 40 to 75%); avoid storage locations that experience
extreme changes in temperature or humidity.
• Avoid locations where dust or harmful gases are present and
avoid direct sunlight.
• Reinspect for rust on leads and solderability of products that have
been stored for a long time.
Cautions for Testing and Handling
When tests are carried out during inspection testing and other
standard test periods, protect the products from power surges
from the testing device, shorts between adjacent products, and
shorts to the heatsink.
Remarks About Using Silicone Grease with a Heatsink
• When silicone grease is used in mounting this product on a
heatsink, it shall be applied evenly and thinly. If more silicone
grease than required is applied, it may produce stress.
• Volatile-type silicone greases may permeate the product and
produce cracks after long periods of time, resulting in reduced
heat radiation effect, and possibly shortening the lifetime of the
product.
• Our recommended silicone greases for heat radiation purposes,
which will not cause any adverse effect on the product life, are
indicated below:
Type
Suppliers
G746
Shin-Etsu Chemical Co., Ltd.
YG6260
Momentive Performance Materials, Inc.
SC102
Dow Corning Toray Silicone Co., Ltd.
Soldering
• When soldering the products, please be sure to minimize the
working time, within the following limits:
260±5°C 10 s
380±10°C 5 s
• Soldering iron should be at a distance of at least 1.5 mm from the
body of the products
Electrostatic Discharge
• When handling the products, operator must be grounded.
Grounded wrist straps worn should have at least 1 MΩ of
resistance to ground to prevent shock hazard.
• Workbenches where the products are handled should be
grounded and be provided with conductive table and floor mats.
• When using measuring equipment such as a curve tracer, the
equipment should be grounded.
• When soldering the products, the head of soldering irons or the
solder bath must be grounded in other to prevent leak voltages
generated by them from being applied to the products.
• The products should always be stored and transported in our
shipping containers or conductive containers, or be wrapped in
aluminum foil.
