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 with the component mounted on a high effective thermal conductivity test board in free air, with “direct attach” features. See
Tech Brief TB379 for details.
2. For θ JC , the “case temp” location is the center of the exposed metal pad on the package underside.
Electrical Specifications
Test Conditions: V CC = 12V, T J = 0°C to +85°C, Unless Otherwise Noted. 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.
