5.2 Handling Precautions

Transportation · Put package boxes in the correct direction. Putting them upside down, leaning them or
giving them uneven stress might cause electrode terminals to be deformed or resin case to
be damaged.
· Throwing or dropping the packaging boxes might cause the devices to be damaged.
· Wetting the packaging boxes might cause the breakdown of devices when operating. Pay
attention not to wet them when transporting on a rainy or a snowy day.
Storage · We recommend temperature and humidity in the ranges 5-35°C and 45-75%, respectively,
for the storage of modules. The quality or reliability of the modules might decline if the
storage conditions are much different from the above.
Long storage · When storing modules for a long time (more than one year), keep them dry. Also, when
using them after long storage, make sure that there is no visible flaw, stain or rust, etc. on
their exterior.
· Keep modules away from places where water or organic solvent may attach to them directly
Surroundings
or where corrosive gas, explosive gas, fine dust or salt, etc. may exist. They might cause
serious problems.
· The epoxy resin and the case materials are flame-resistant type (UL standard 94-V0), but
Flame
resistance they are not noninflammable.
· ICs and power chips with MOS gate structure are used for the DIPIPM power modules.
Static electricity
Please keep the following notices to prevent modules from being damaged by static
electricity.
(1)Precautions against the device destruction caused by the ESD
(2)Notice when the control terminals are open
Publication Date: September 2016
Cautions
！
The ESD of human bodies and packaging and/or excessive voltage applied across the
gate to emitter may damage and destroy devices. The basis of anti-electrostatic is to
inhibit generating static electricity possibly and quick dissipation of the charged electricity.
·Containers that charge static electricity easily should not be used for transit and for
storage.
·Terminals should be always shorted with a carbon cloth or the like until just before using
the module. Never touch terminals with bare hands.
·Should not be taking out DIPIPM from tubes until just before using DIPIPM and never
touch terminals with bare hands.
·During assembly and after taking out DIPIPM from tubes, always earth the equipment
and your body. It is recommended to cover the work bench and its surrounding floor
with earthed conductive mats.
·When the terminals are open on the printed circuit board with mounted modules, the
modules might be damaged by static electricity on the printed circuit board.
·If using a soldering iron, earth its tip.
·When the control terminals are open, do not apply voltage between the collector and
emitter. It might cause malfunction.
·Short the terminals before taking a module off.
