Description
The SCM1103M 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 85 to 253 VAC input voltage, and 10 A (continuous) output
current. They can withstand voltages of up to 600 V (IGBT
breakdown voltage).
The SCM1100M series employs a new, small-footprint
proprietary DIP package. The IC itself consists of all of the
necessary power elements (six IGBTs), pre-drive ICs (three),
and flyback diodes (six), needed to configure the main circuit of
an inverter, as well as a bootstrap circuit (three bootstrap diodes
and three boot resistors) as a high-side drive power supply. This
enables the main circuit of the inverter to be configured with
fewer external components than traditional designs.
Applications include residential white goods (home appliances)
and commercial appliance motor control, such as:
▪ Air conditioner fan motor
▪ Refrigerator compressor motor
▪ Washing machine main motor
▪ Air conditioner compressor motor

NOTE:
▪ All of the input pins are connected to GND with internal pull-down resistors rated at 100 kΩ, however, an external pull-down
resistor may be required to secure stable condition of the inputs if high impedance conditions are applied to them.
▪ To use the OCP circuit, an external shunt resistor, RS, is needed. The RS value can be obtained from the formula:
RS(Ω) = 0.5 V / Overcurrent Detection Set Current (A) .
▪ A blanking timer is built-in to mask the noise generated on RS at turn-on.
▪ The external electrolytic capacitors should be placed as close to the IC as possible, in order to avoid malfunctions from
external noise interference. Put a ceramic capacitor in parallel with the electrolytic capacitor if further reduction of noise
susceptibility is necessary.

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. Pre cau tions must be
taken to prevent accidental contact with power-line potentials. Do not connect ground ed 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 GE Toshiba Silicone Co., Ltd.
SC102 Dow Corning Toray Silicone Co., Ltd.
Heatsink Mounting Method
Torque When Tightening Mounting Screws. The recommended tightening
torque for this product package type is: 58.8 to 78.4 N•cm (6.0 to
8.0 kgf•cm).
Soldering
• When soldering the products, please be sure to minimize the
working time, within the following limits:
260±5°C 10 s
380±5°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.
