Notes

• The rated dissipation applies only if the permitted film temperature is not exceeded. Furthermore, a high level of ambient temperature or of

power dissipation may raise the temperature of the solder joint, hence special solder alloys or board materials may be required to maintain

the reliability of the assembly. Specified power rating above standard operation mode requires dedicated heat-sink pads, which to a great

extend depend on board materials and design. The given solder pad dimensions reflect the considerations for board design and assembly as

as these are also strongly influenced by many other parameters.



Please note however that applications for "power operation mode" require special considerations for the design of solder pads and adjacent

conductor areas.
