reliability and result in failures not covered by warranty.
NOTES:
5. θ_JA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
6. 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.
7. For θ_JC, the “case temp” location is the center of the exposed metal pad on the package underside.
8. For θ_JC, the “case temp” location is taken at the package top center
Electrical Specifications V_CC = BIAS = 12V, unless otherwise stated. T_A = +25°C to +85°C. Boldface limits apply over the operating
temperature range, -40°C to +125°C.
