OPERATING PRECAUTIONS
In the case that you use Sanken products or design your products by using Sanken products, the reliability largely
depends on the degree of derating to be made to the rated values. Derating may be interpreted as a case that an operation
range is set by derating the load from each rated value or surge voltage or noise is considered for derating in order to
assure or improve the reliability. In general, derating factors include electric stresses such as electric voltage, electric
current, electric power etc., environmental stresses such as ambient temperature, humidity etc. and thermal stress caused
due to self-heating of semiconductor products. For these stresses, instantaneous values, maximum values and minimum
values must be taken into consideration. In addition, it should be noted that since power devices or IC’s including power
devices have large self-heating value, the degree of derating of junction temperature affects the reliability significantly.
Because reliability can be affected adversely by improper storage environments and handling methods, please
observe the following cautions.
Cautions for Storage
 Ensure that storage conditions comply with the standard temperature (5 to 35°C) and the standard relative humidity
(around 40 to 75%); avoid storage locations that experience extreme changes in temperature or humidity.
 Avoid locations where dust or harmful gases are present and avoid direct sunlight.
 Reinspect for rust on leads and solderability of the products that have been stored for a long time.
Cautions for Testing and Handling
When tests are carried out during inspection testing and other standard test periods, protect the products from power
surges from the testing device, shorts between the product pins, and wrong connections. Ensure all test parameters are
within the ratings specified by Sanken for the products.
Remarks About Using Thermal Silicone Grease
 When thermal silicone grease is used, it shall be applied evenly and thinly. If more silicone grease than required is
applied, it may produce excess stress.
 The thermal silicone grease that has been stored for a long period of time may cause cracks of the greases, and it
cause low radiation performance. In addition, the old grease may cause cracks in the resin mold when screwing the
products to a heatsink.
 Fully consider preventing foreign materials from entering into the thermal silicone grease. When foreign material
is immixed, radiation performance may be degraded or an insulation failure may occur due to a damaged insulating
plate.
 The thermal silicone greases that are recommended for the resin molded semiconductor should be used.
Our recommended thermal silicone grease is the following, and equivalent of these.

Cautions for Mounting to a Heatsink
 When the flatness around the screw hole is insufficient, such as when mounting the products to a heatsink that has
an extruded (burred) screw hole, the products can be damaged, even with a lower than recommended screw torque.
For mounting the products, the mounting surface flatness should be 0.05mm or less.
 Please select suitable screws for the product shape. Do not use a flat-head machine screw because of the stress to
the products. Self-tapping screws are not recommended. When using self-tapping screws, the screw may enter the
hole diagonally, not vertically, depending on the conditions of hole before threading or the work situation. That
may stress the products and may cause failures.
 Recommended screw torque:
Package
Recommended Screw Torque
TO-220, TO-220F
0.490 to 0.686 N・m (5 to 7 kgf・cm)
TO-3P, TO-3PF, TO-247
0.686 to 0.882 N・m (7 to 9 kgf・cm)
SLA
0.588 to 0.784 N・m (6 to 8 kgf・cm)

 For tightening screws, if a tightening tool (such as a driver) hits the products, the package may crack, and internal
stress fractures may occur, which shorten the lifetime of the electrical elements and can cause catastrophic failure.
Tightening with an air driver makes a substantial impact. In addition, a screw torque higher than the set torque can
be applied and the package may be damaged. Therefore, an electric driver is recommended.
When the package is tightened at two or more places, first pre-tighten with a lower torque at all places, then tighten
with the specified torque. When using a power driver, torque control is mandatory.
 Please pay special attention about the slack of the press mold. In case that the hole diameter of the heatsink is less
than 4 mm, it may cause the resin crack at tightening.
Soldering
 When soldering the products, please be sure to minimize the working time, within the following limits:
• 260 ± 5 °C
10 ± 1 s (Flow, 2 times)
• 380 ± 10 °C 3.5 ± 0.5 s (Soldering iron, 1 time)
 Soldering should be at a distance of at least 1.5 mm from the body of the products.
