OPERATION OF PROTECTION CIRCUIT(1)

APPLICATION CIRCUIT EXAMPLE

In case the gate voltage is “H” and the collector voltage ishigh, this hybrid IC will recognize the circuit as short

4.7k

circuit and immediately reduce the gate voltage.
Besides, put out an error signal (”L”) which inform that8

PRECAUTION

START(1)Voltage compensate capacitors are expected to be locatedas close as possible from the hybrid IC.
(2)D1 requires approximately the same voltage of power modules.
DETECTION OF
SHORT CIRCUIT(3)If reverse recovery time of D1 is long, pin1 is applied high voltage.
In that case, counterplan for protection which insert a zener
diode between pin 1 and 6 is necessary like above diagram.
(4)In case pin 2 is operating, the Ctrip is expected to be wired
as close as possible from pin 2 and pin 4.

FOR SAFETY USINGGreat detail and careful attention are given to the production activity of Hics, such as the development, the quality of production, andin it’s reliability. However the reliability of Hics depends not only on their own factors but also in their condition of usage. When handlingHics, 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.

CarryingStorage

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 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)

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 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.
