PRECAUTION
(1)
(2)
(3)
(4)

Voltage compensate capacitors are expected to be located as close as possible to the Hybrid IC.
Minimize the area of closed circuit of gate circuit so as not to be affected by induction noise.
D1 requires approximately the same voltage of IGBT modules.
When recovery current flow in D1, pin 30 is applied high voltage.
In that case, counterplan for protection which insert a zener diode between pin21 and 30 are necessary like above diagram.
(5) When you make late speed of reverse bias at the time of short circuit protection operation,please adjust and connect a capacitor between pin 21 and 27.
(6) When the built in short-circuit protection circuit need not be used, please connect resistance of 4.7k ohm between pin 30 and 20.
(D1 and Dz1 are not required.)(7) When the collector clamp circuit operates repeatedly, it may be destroied for heat. That is why the confirmation of calorific value
is necessary for zener diode by actual inverter test.

HYBRID IC

VLA554-01R
DRIVER FOR IGBT MODULESFOR SAFETY USINGGreat detail and careful attention are given to the production activity of Hics, such as the development, the quality of production, andin its 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

Carrying

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.
1)
2)
3)
4)
5)

Don’t stack boxes too high. Avoid placing heavy materials on boxes.
Boxes must be positioned correctly during transportation to avoid breakage.
Don't throw or drop boxes.
Keep boxes dry. Avoid rain or snow.
Minimal vibration and shock during transportation is desirable.

Storage

When storing Hics, please observe the following notices or possible deterioration of their electricalcharacteristics, 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 withhumidity at 40 to 60%.
2) 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.

Extended storage

When extended storage is necessary, Hics must be kept non-processed. When using Hics whichhave 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 ininserting leads into the board holes, conforming to the external view for the terminal arrangement.
