APPLICATION INFORMATION (CONT.)
6.) Heat dissipation
Make the copper pattern as large as possible to provide
good heat dissipation (pin 5 is the heatsink).
Maximum power dissipation = 400 mW (When mounted as
recommended) See Figure C.

7.) Handling molded resin packages
All plastic molded packages absorb some moisture from
the air. If moisture absorption occurs prior to soldering the
devise into the printed circuit board, increased separation
of the lead from the plastic molding may occur, degrading
the moisture barrier characteristics of the device. This
property of plastic molding compounds should not be
overlooked, particularly in the case of very small packages,
where the plastic is very thin. In order to preserve the
original moisture barrier properties of the package, devices
are stored and shipped in moisture proof bags, filled with
dry air. The bags should not be opened or damaged prior
to the actual use of the devices. If this is unavoidable, the
devices should be stored in a low relative humidity environ-
ment (40 to 65%) or in an enclosed environment with
desiccant.
