CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
+150°C max junction temperature is intended for short periods of time to prevent shortening the lifetime. Constantly operated at 150°C may shorten the life of the part.
NOTES:
1. θ_JA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features.
2. θ_JC, “case temperature” location is at the center of the package underside exposed pad. See Tech Brief TB379 for details.
Electrical Specifications These specifications apply for T_A = 0°C to +70°C, unless otherwise noted
