Application Information (continued)

TR(max) is calculated by the using to formula:

TR(max) = TJ(max) – TA(max)

Where: TJ(max) is the maximum allowable junction

temperature, which is 125

oC for commercial

grade parts.TA(max) is the maximum ambient

temperature which will be encountered in the

application.

Using the calculated values for TR(max) and PD, the

maximum allowable value for the junction to ambient

thermal resistance,

θja, can now be found:

θja = TR(max) / PD

IMPORTANT:

if the maximum allowable value for is

found to be ≥60

oC/W for the TO-220 package, ≥80

oC/W for the TO-263 package, ≥150 oC/W for the

TO-252 package, or ≥170

oC/W for the SOT-223

package, no heatsink is needed since the package

alone will dissipate enough heat to satisfy these

requirements. If the calculated value for

θja falls below

these limits, a heatsink is required.
