CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product reliability and
result in failures not covered by warranty.
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. See
Tech Brief TB379.
2. For θ_JC, the “case temp” location is the center of the exposed metal pad on the package underside.
Electrical Specifications
These specifications apply for T_A = -10°C to +100°C, unless otherwise noted. Typical values are at T_A = +25°C,
V_IN = 12V; Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified.
Temperature limits established by characterization and are not production tested.
