Installation
Storage
・Soldering involves temperatures which exceed the device storage temperature rating. To avoid
・The immersion depth of the lead should basically be up to the lead stopper and the distance
・When flow-soldering, be careful to avoid immersing the package in the solder bath.
・Refer to the following torque reference When mounting the device on a heat sink. Excess torque
・The heat sink should have a flatness within ±30μm and roughness within 10μm. Also, keep
・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. It is
・The Diodes must be stored at a standard temperature of 5 to 35℃ and relative humidity of 45 to
・The Diodes should not be subjected to rapid changes in temperature to avoid condensation on
・The Diodes should not be stored on top of each other, since this may cause excessive external
・The Diodes should not be stored with the lead terminals remaining unprocessed. Rust may cause
・The Diodes should be stored in antistatic containers or shipping bags.
