Input voltage
Continuous total dissipation (see Note 1)
Operating free-air, case, or virtual junction temperature range
Storage temperature range
Lead temperature 1,6 mm (1/16 inch) from case for 10 seconds
NOTE 1: To avoid exceeding the design maximum virtual junction temperature, these ratings should not be exceeded. 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.
