The footprint for the semiconductor packages must be the correct size to ensure proper solder connection interface between the board and the package. The minimum recommended footprint for the SOD-123 is shown at the right. The SOD-123 package can be used on existing surface mount boards which have been designed for the leadless 34 package style. The footprint compatibility makes conversion from leadless 34 to SOD-123 straightforward. 0.91 0.036 2.36 0.093 4.19 0.165 Figure 11. Minimum Recommended Footprint SOD-123 POWER DISSIPATION The power dissipation of the SOD-123 is a function of the pad size. This can vary from the minimum pad size for soldering to a pad size given for maximum power dissipation. Power dissipation for a surface mount device is determined by TJ(max), the maximum rated junction temperature of the die, RθJA, the thermal resistance from the device junction to ambient; and the operating temperature, TA. Using the values provided on the data sheet for the SOD-123 package, PD can be calculated as follows: TJ(max) – TA RθJA ratings table on the data sheet. Substituting these values into the equation for an ambient temperature TA of 25°C, one can calculate the power dissipation of the device which in this case is 0.37 watts. PD = 150°C – 25°C = 0.37 watts 340°C/W PD = The values for the equation are found in the maximum The 340°C/W for the SOD-123 package assumes using r
