*1 At Ta＝25°C or higher, this value is decreased to 5.5mW/°C. Thermal resistance

ja = 181.8 (°C/W).

*2 At Ta＝25°C or higher, this value is decreased to 6.0mW/°C. Thermal resistance

ja = 166.7 (°C/W).

When Rohm standard board is mounted.

Rohm standard board:

size: 70×70×1.6 (mm

material: FR4 glass-epoxy substrate (copper foil area: not more than 3%).

*3 As long as voltage stays within operating voltage range, certain circuit operation is guaranteed in the

operating temperature range.

Allowable loss conditions are related to temperature, to which care must be taken.

In addition though the standard value of its electrical characteristics cannot be guaranteed under the

conditions other than those specified, original functions are maintained.
