L78M00T Series
The allowable power dissipation (Pd max) is 1.0W (Ta=25°C) with no fin attached. When the L78M00T series are
surface-mounted on a hybrid IC board or printed circuit board, a high allowable power dissipation can be obtained,
though they are placed in a small-sized package.
Shown below is the relationship between the Cu-foiled area and the allowable power dissipation when the L78M00T
series are surface-mounted on a glass epoxy board (50✕50✕0.8mm3).

Specifications of any and all SANYO products described or contained herein stipulate the performance,
characteristics, and functions of the described products in the independent state, and are not guarantees
of the performance, characteristics, and functions of the described products as mounted in the customer’s
products or equipment. To verify symptoms and states that cannot be evaluated in an independent device,
the customer should always evaluate and test devices mounted in the customer’s products or equipment.
SANYO Electric Co., Ltd. strives to supply high-quality high-reliability products. However, any and all
semiconductor products fail with some probability. It is possible that these probabilistic failures could
give rise to accidents or events that could endanger human lives, that could give rise to smoke or fire,
or that could cause damage to other property. When designing equipment, adopt safety measures so
that these kinds of accidents or events cannot occur. Such measures include but are not limited to protective
circuits and error prevention circuits for safe design, redundant design, and structural design.
