THE WAY TO CALCULATE GATE RESISTANCE VALUE OF PARALLEL CONNECTION
RG_ON/1elem. = Gate ON resistance value per one element = Rb + (N x Rg_on)
RG_OFF/1elem. = Gate OFF resistance value per one element = Rb + (N x Rg_off)
Rb: 2.35Ω (Compound value of 4 chip resistors on VLB521-01R)
N: Parallel number of modules
Rg_on : Gate ON resistance value on gate drive unit
Rg_off : Gate OFF resistance value on gate drive unit

FOR SAFETY USINGGreat detail and careful attention are given to the production activity of Hics, such as the development, the quality ofproduction, and in itʼs reliability. However the reliability of Hics depends not only on their own factors but also intheir 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, thepacking materials will deteriorates. Please take care in handling.
1)
2)
3)
4)
5)

Donʼt 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 electrical characteristics, risk of solder ability, and external damage may occur.
1)
Devices must be stored where fluctuation of temperature and humidity isminimal, 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)
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.

Extendedstorage

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, besure to check that the exterior is free from flaw and other damages.

Maximumratings

To prevent any electrical damages, use Hics within the maximum ratings. Thetemperature, current, voltage, etc. must not exceed these conditions.

Polarity

To protect Hics from destruction and deterioration due to wrong insertion, make sureof polarity in inserting leads into the board holes, conforming to the external view for
the terminal arrangement.
