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

(966 mW × 20.1°C/W) = 19.4°C

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

TJ = 85°C + 19.4°C = 104°C

This junction temperature is below the maximum allowable.

Example 2

(2500 mW × 20.1°C/W) = 50.2°C

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

TJ = 85°C + 50°C = 135°C

This junction temperature is above the maximum allowable. The

ambient temperature must be lowered by 20°C to operate in the

condition of Example 2.

GUIDELINES

Refer to the AN-772 Application Note, A Design and

Manufacturing Guide for the Lead Frame Chip Scale Package

(LFCSP), for more information about mounting devices with

an exposed paddle.
