*1: The characteristic shall not exceed the package permissible loss (Pd).
SOP-8 (E-Pad)
When Ta is 25°C, the permissible loss is the level when a 4-layer board (50 mm x 40 mm) is mounted and
the exposed pad connected by solder.
When Ta is more than 25°C, the load is rated at light SOP-8 (E-Pad) of (θj-a = 32°C/W). At such time, let θj-c
= 17°C/W.
DIP-8
When Ta is 25°, the permissible loss is the level when a 2-layer board (50 mm x 4 DIP-8) is mounted.
If Ta is more than 25°C, the Pd is derated at a load reduction rate of (θj-a = 95°C/W).
At such time, let θj-c = 55°C/W.
Note: To use this IC, do so within the heat characteristic range indicated above when Tj is 150°C or less.
When actually using this IC, measure the case temperature or take some other measure to ensure that Tj is
150°C or less.
