PRECAUTION
(1)
Voltage compensate capacitors are expected to be located as close as possible to the Hybrid IC.
(2)
Minimize the area of closed circuit of gate circuit so as not to be affected by induction noise.
(3)
D1 requires approximately the same voltage of power modules.
(4)
When recovery current flow in D1 , pin 30 is applied high voltage .
In that case , counterplan for protection which insert a zener diode between pin 21,22 and 30 are necessary like above diagram.
(5)
When the built in short-circuit protection circuit is not necessary to be used, please connect resistor of 4.7k ohm between pin 30 and 20.
(D1 and Dz1 are not required.)

FOR SAFETY USING
Great detail and careful attention are given to the production activity of Hics, such as the development, the quality of production, and
in it’s reliability.
However the reliability of Hics depends not only on their own factors but also in their condition of usage. When
handling Hics, please note the following cautions.
CAUTIONS
Packing
The materials used in packing Hics can only withstand normal external conditions.
When exposed to outside shocks, rain and certain environmental contaminators, the packing materials
will deteriorates. Please take care in handling.
Carrying
Storage
1)
Don’t stack boxes too high. Avoid placing heavy materials on boxes.
2)
Boxes must be positioned correctly during transportation to avoid breakage.
3)
Don't throw or drop boxes.
4)
Keep boxes dry. Avoid rain or snow.
5)
Minimal vibration and shock during transportation is desirable.
When storing Hics, please observe the following notices or possible deterioration of their electrical
characteristics, risk of solder ability, and external damage may occur.
1)
Devices must be stored where fluctuation of temperature and humidity is minimal, and must not
be exposed to direct sunlight. Store at the normal temperature of 5 to 30 degrees Celsius with
humidity at 40 to 60%.
2)
Extended storage
Avoid locations where corrosive gasses are generated or where much dust accumulates.
3)
Storage cases must be static proof.
4)
Avoid putting weight on boxes.
When extended storage is necessary, Hics must be kept non-processed. When using Hics which
have been stored for more than one year or under severe conditions, be sure to check that the exterior
is free from flaw and other damages.
Maximum ratings
To prevent any electrical damages, use Hics within the maximum ratings. The temperature, current,
voltage, etc. must not exceed these conditions.
Polarity
To protect Hics from destruction and deterioration due to wrong insertion, make sure of polarity in
inserting leads into the board holes, conforming to the external view for the terminal arrangement.
