Data Sheet

The second step is to multiply the power dissipated by the

thermal impedance to determine the maximum power

gradient. For this example, a thermal impedance of θJA =

20.1°C/W was used.

Example 1

(703 mW × 20.1°C/W) = 14.1°C

With an ambient temperature of 85°C, the junction temperature is

TJ = 85°C + 14.1°C = 99°C

This junction temperature is below the maximum allowable.

Example 2

(1223 mW × 20.1°C/W) = 24.6°C

With an ambient temperature of 85°C, the junction temperature is

TJ = 85°C + 24.6°C = 109°C

This junction temperature is below the maximum allowable.
