NOTES:
1. All voltage values are with respect to the network ground terminal.
2. For operation above 25
°
C free-air temperature, derate linearly at the rate of 16.6 mW/
°
C.
3. For operation above 25
°
C case temperature, derate linearly at the rate of 71.4 mW/
°
C. Due to variations in individual device electrical
characteristics and thermal resistance, the built-in thermal overload protection may be activated at power levels slightly above or
below the rated dissipation.
