Recommended that space is 2.0 to 3.0 mm typical. (2) Recommended torque strength of the screw is 59 to 78 Ncm. (3) Form the ground pattern as wide as possible to minimize ground impedance. (to prevent undesired oscillation) All the ground pins must be connected together with wide ground pattern to decrease impedance difference. RECOMMENDED SOLDERING CONDITIONS This product should be soldered and mounted under the following recommended conditions. For soldering methods and conditions other than those recommended below, contact your nearby sales office. Soldering Method Partial Heating Soldering Conditions Peak temperature (pin temperature) : 350°C or below Soldering time (per pin of device) Recommended Condition Symbol Note : 3 seconds or less Note The point of pin part heating must be kept more than 1.2 mm distance from the root of lead. 4 Data Sheet PG10313EJ01V0DS − MC-7881 • The information in this document is current as of January, 2003.

To minimize risks of damage to property or injury (including death) to persons arising from defects in NEC semiconductor products, customers must incorporate sufficient safety measures in their design, such as redundancy, fire-containment, and anti-failure features. • NEC semiconductor products are classified into the following three quality grades: "Standard", "Special" and "Specific". The "Specific" quality grade applies only to semiconductor products developed based on a customer-designated "quality assurance program" for a specific application. The recommended applications of a semiconductor product depend on its quality grade, as indicated below. Customers must check the quality grade of each semiconductor product before using it in a particular application. "Standard": Computers, office equipment, communications equipment, test and measurement equipment, audio and visual equipment, home electronic appliances, machine tools, personal electronic equipment and industrial robots "Special": Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster systems, anti-crime systems, safety equipment and medical equipment (not specifically designed for life support) "Specific": Aircraft, aerospace equipment, submersible repeaters, nuclear reactor control systems, life support systems and medical equipment for life support, etc. The quality grade of NEC semiconductor products is "Standard" unless otherwise expressly specified in NEC's data sheets or data books, etc. If customers wish to use NEC semiconductor products in applications not intended by NEC, they must contact an NEC sales representative in advance to determine NEC's willingness to support a given application. (Note) (1) "NEC" as used in this statement means NEC Corporation, NEC Compound Semiconductor Devices, Ltd. and also includes its majority-owned subsidiaries. (2) "NEC semiconductor products" means any semiconductor product developed or manufactured by or for NEC (as defined above).
