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.

θJA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.

2.

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.

3. For

θJC, the “case temp” location is the center of the exposed metal pad on the package underside.

4. Limits should be considered typical and are not production tested.

Electrical Specifications

Recommended Operating Conditions. 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
