Description
Description
With the introduction of smaller surface mount (SMT) packages, it is becoming increasingly important to know their maximum power handling capability in specific applications. The power dissipation capability is directly proportional to size. As the size decreases, the amount of power that the package can dissipate decreases. Also, with the development of new high performance packages such as MSOPs, MLPs and SC70s, it is important to know how much power the package can reliably dissipate. Data sheets and package manufactures provide power handling data for packages using industry standard test setups. It is impossible to specify the capability for specific applications. The actual power handling capability can vary significantly depending on many application specific variables.
