Storage, characteristic inspection, and handling precautions
Inappropriate storage, characteristic inspection, or
5. Soldering temperature
handling may impair the reliability of the device. To ensure
high reliability, observe the following precautions:
If soldering is necessary, take care to keep the applica-
tion of heat as brief as possible, and within the following
limits:
1. Storage precautions
260±5ºC for 10 s max
It is recommended to store the device at room temper-
•
350ºC for 3 s max (soldering iron)
ature (between 5 and 35°C) and relative humidity at 40 to
75%. Avoid storing the device in a place where the
temperature or humidity is high or changes greatly.
6. Heatsink
Store the device in a clean place that is not exposed to
A large contact area between the device and the
heatsink for effective heat radiation is required. To ensure
a large contact area, minimize mounting holes and select a
heatsink with a sufficiently smooth surface and that is free
from burring or metal debris.
•
direct sunlight, and is free from corrosive or harmful
gases.
If the device is stored for a long time, check the solder-
•
ability and lead condition before using the device.
2. Precautions on characteristic inspections
7. Handling precautions to protect power
MOS FET from static damage
When carrying out characteristic inspections on re-
ceiving products or other occasions, take care to avoid
applying a surge voltage from the measuring equipment
and check the terminals of the measuring equipment for a
short circuit or wiring errors. Measure the device within the
range of its rated values.
When handling the device, physical grounding is neces-
•
sary. Wear a wrist strap with a 1 MΩ resistor close to the
body in the wrist strap to prevent electric shock.
Use a conductive table mat or floor mat at the device
•
handling workbench and to ensure grounding.
When using a curve tracer or other measuring equip-
•
ment, ground the equipment as well.
3. Silicone Grease
When soldering, ground the bit of the soldering iron and
•
When attaching heatsink, apply a small amount of
silicone evenly to the back of the device and both sides of
the insulator to reduce the thermal resistance between the
device and heatsink.
the dip tank to prevent a leakage voltage from damaging
the device.
Store the device in the shipping container or a conduc-
•
tive container or use aluminum foil to protect the device
from static electricity.

8. Load on Leads
SC102 DOW CORNING TORAY SILICONE CO., LTD.
When excessive load is exerted on leads, internal
connections may be break. Load exerted in each of the
following directions should be limited to below 1 kg for
TO-220F and 2.5 kg for TO-3PF.
Please select a silicone grease carefully since the oil in
some grease can penetrate the product, which will
result in an extremely short product life.
4. Screw tightening torque
If screws are not tightened with sufficient torque, this
can increase the thermal resistance and reduce the
radiation effect. Tightening screws with too great a torque
damage the screw thread, deform the heatsink, or twist the
device frame until it is damaged. There, tighten screws with
a torque as shown below (Table 1).

0.490 to 0.686 N•m (5 to 7 kgf•cm)
0.686 to 0.822 N•m (7 to 9 kgf•cm)
We make several types of lead forming available, please
consult with our personnel when necessary.
