･ Improper handling may cause isolation breakdown leading to a critical accident.
･ We recommend the use of thermal compound to optimize the efficiency of heat radiation.
Storage
･ The MOSFETs must be stored at a standard temperature of 5 to 35 ｰ C and relative
･ If the storage area is very dry, a humidifier may be required. In such a case, use only
･ The MOSFETs should not be subjected to rapid changes in temperature to avoid
･ The MOSFETs should not be stored on top of each other, since this may cause
･ The MOSFETs should be stored with the lead terminals remaining unprocessed. Rust
･ The MOSFETs should be stored in antistatic containers or shipping bags.
applied to the mounting screw causes damage to the device and weak torque will increase the
thermal resistance, both of which conditions may destroy the device.
keep the tightening torque within the limits of this specification.

It is important to evenly apply the compound and to eliminate any air voids.
humidity of 45 to 75%.
deionized water or boiled water, since the chlorine in tap water may corrode the leads.
condensation on the surface of the MOSFETs. Therefore store the MOSFETs in a place
where the temperature is steady.
