Circuit designs that embody these components must conform with applicable safety requirements. Precautions must be taken to prevent accidental contact with power-line potentials. Do not connect grounded test equipment. The use of an isolation transformer is recommended during circuit development and breadboarding. 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 (5C to 35C) 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 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 adjacent products, and shorts to the heatsink. Remarks About Using Silicone Grease with a Heatsink * When silicone grease is used in mounting this product on a heatsink, it shall be applied evenly and thinly. If more silicone grease than required is applied, it may produce stress. * Coat the back surface of the product and both surfaces of the insulating plate to improve heat transfer between the product and the heatsink. * Volatile-type silicone greases may permeate the product and produce cracks after long periods of time, resulting in reduced heat radiation effect, and possibly shortening the lifetime of the product. * Our recommended silicone greases for heat radiation purposes, which will not cause any adverse effect on the product life, are indicated below: Type Suppliers G746 Shin-Etsu Chemical Co., Ltd. YG6260 Momentive Performance Materials SC102 Dow Corning Toray Silicone Co., Ltd. Heatsink Mounting Method * Torque When Tightening Mounting Screws. Thermal resistance increases when tightening torque is low, and radiation effects are decreased. When the torque is too high, the screw can strip, the heatsink can be deformed, and distortion can arise in the product frame. To avoid these problems, observe the recommended tightening torques for this product package type 0.686 to 0.882 N*m (7 to 9 kgf*cm). * For effective heat transfer, the contact area between the product and the heatsink should be free from burrs and metal fragments, and the heatsink should be flat and large enough to contact over the entire side of the product, including mounting flange and exposed thermal pad. * The mounting hole in customer-supplied heatsink must be less than O4 mm; this includes the diameter of any dimple around punched holes. This is to prevent possible deflection and cracking of the product case when fastened to the heatsink. Soldering * When soldering the products, please be sure to minimize the working time, within the following limits: 2605C 10 s 3505C 3 s * Soldering iron should be at a distance of at least 1.5 mm from the body of the products Electrostatic Discharge * When handling the products, operator must be grounded. Grounded wrist straps worn should have at least 1 M of resistance to ground to prevent shock hazard. * Workbenches where the products are handled should be grounded and be provided with conductive table and floor mats. * When using measuring equipment such as a curve tracer, the equipment should be grounded. * When soldering the products, the head of soldering irons or the solder bath must be grounded in other to prevent leak voltages generated by them from being applied to the products. * The products should always be stored and transported in our shipping containers or conductive containers, or be wrapped in aluminum foil.
